    DESIGN AND DEVELOPMENT OF ARCTIC TRADING VESSELS

            Arctic trading vessels, as a distinct class or commercial type, were of

    comparatively recent origin. Excluding the early whalers and sealers, who

    usually carried on some trading with the Eskimos during the winter months when

    opportunity offered, the arctic trading vessels were employed by either the

    established fur-trading companies or by independents, usually trading as in–

    dividuals. With respect to the fur companies, they did not engage in exten–

    sive arctic trading until well toward the end of the 19th century, by which

    time they had begun to establish trading posts in the Arctic. Once the posts

    were in operation, it was a short step to the employment of trading craft work–

    ing out of some of the posts or acting as carriers and supply vessels to isolated

    stations. Most of these craft were primarily supply ships and so, in general,

    the fur company craft were large. In the Eastern Arctic, particularly Hudson

    Bay, some of the companies operated small craft between their large distributing

    posts and the small outlying stations. In the Western Arctic trade was perhaps

    more closely related withwhaling, as many whaling ships established permanent

    posts ashore which not only carried on trade with the Eskimos for furs but also

    employed these people in an extensive and, for a long period, a very prosperous

    shore whaling industry. Following closely these whaling establishments, indiv–

    idual traders from the American and Canadian Pacific coasts entered the Arctic;

    these appeared in large numbers in the 1890's. In periods of gold-rush excite–

    ment in Alaska and western Canada, the arctic trade underwent rapid expansion;

    most of the trading vessels not only carried trade goods to the Arctic but

    also engaged in passenger and freight carrying along the Alaskan coast. These

    vessels operated out of the Pacific ports, particularly from Seattle and Van–

    couver.

            In the east the independent traders developed less rapidly; the fur com–

    panies controlled most of the area and their establishments were made very

    early, many of them coming into existence soon after the Greenland whaling

    and sealing vessels first pushed into Hudson Bay. Some independent traders

    succeeded in establishing themselves, however, but most of these used small

    vessels hailing from Nova Scotia, Quebec, and Newfoundland ports. These east–

    ern traders were never very numberous and cannot be said to have been as pros–

    perous as the traders in the Western Arctic. The eastern traders not only suf–

    fered from competition with the fur companies but also from the trading active–

    ties of the European sealers and whalers. The eastern trade was at its height

    about 1880 and declined thereafter.

            To establish a distinct class of arctic trading vessel, it is necessary

    to confine the discussion to the vessels of the independent traders to a great

    extent. These craft were small and were used in daring voyages into uncharted

    and often unexplored waters in search of trade untouched by the big fur compan–

    ies. These independent traders rarely had a permanent post ashore and usually

    operated as individuals, their only employees being their crews. The method

    of operating this type of arctic trade and the economic limitations involved

    produced some very interesting small craft. The large vessels of the fur com–

    panies and some of the whalers, on the other hand, were either closely related

    to the large whaling and sealing ships in both model and basic requirements or

    were no more than well-built cargo ships carrying freight out of some of the

    003      |      Vol_IX-0139                                                                                                                  
    EA-Transportation. Chapelle: Design and Development of Arctic Trading Vessels

    more important and accessible posts during periods of open navigation; these

    could not be classed as arctic ships in most cases.

            The earliest eastern traders employed small sloops and schooners, first

    along the coast of Labrador and in Hudson Strait, then in Hudson Bay. Some

    trading efforts were made as early as 1750 but what records are available in–

    dicate this trade was a by-product of whaling rather than a wholly independent

    business. In 1830, however, small Canadian fishing schooners were trading in

    north Hudson Bay; this was done only during summer months and the vessels tried

    to return to the Atlantic before ice closed the Strait. From this time on, the

    eastern traders usually employed schooners of the fisherman type in their trad–

    ing ventures and, after about 1850, many of them wintered in the Arctic, par–

    ticularly near Southampton Island, Baffin Island, and on the western side of

    Hudson Bay.

            Nothing is known about the methods [ of ?] these traders used to fit their small

    craft for the ice but it is logical to suppose they followed the well-established

    practices of the sealers and whalers in this matter. During the early 19th cen–

    tury, their trading schooners were not greatly dissimilar to the New London seal–

    ing schooners in appearance but were narrower and deeper, and less heavily rigged.

    As the models of the Nova Scotia fishing schooners changed, so did those of the

    traders, for the practice of building traders on the lines of fisherman became

    very common. During the first years of the 20th century, the gasoline engine

    became common in the small traders; auxiliary power sufficiently compact for a

    small vessel had not been available in steam, though arctic navigation placed a

    premium on a combination of mechanical and sail propulsion.

            Figure 1 shows one of the relatively recent designs for small trading ves–

    sels built for the Eastern Arctic. This small schooner was designed and built

    004      |      Vol_IX-0140                                                                                                                  
    EA-Transportation. Chapelle: Design and Development of Arctic Trading Vessels

    under the supervision of her master, a man with wide experience in arctic trade

    and so may be accepted as a vessel suited for the work. The design of the hull

    is in no way dissimilar to that of a small fishing schooner; the compact and

    easily handled rig is the only departure. The short "schooner" bow has been

    a matter of disagreement among the traders, however; some prefer less overhang.

    The small size of the traders generally makes any tendency to ride up onto the ice

    useless, as the small weight of these boats is usually in- sufficient to break ice

    of any great thickeness and so the cutaway stem profile might cause the boat to

    get "hung up" on an ice floe.

            But while a design such as used in Nansen's Fram, to allow riding-up under

    pressure, was not of much advantage except to fairly large craft, a slightly

    analogous method for escaping ice pressure was sometimes used by small trading

    vessels. One such was the power schooner North Star , built on the Pacific coast

    around 1910 for Martin Andreasen, and experienced and successful trapper-trader,

    to draw only about three feet forward when fully loaded, a foot more aft. Stef–

    ansson's The Friendly Arctic , pages 102-103, has an account of this vessel, of

    Captain Andreasen's theories about her, and of his method for escaping ice pres–

    sure, which explains the method, as follows:

            ". . . Matt Andreasen and the North Star had a system . . . . The basic

    idea is that on most of the north coast of Alaska and north coast of Canada the

    ocean is shallow inshore, with a number of rivers in the spring bringing warm

    water from the land to melt away the inshore ice. It happens frequently that

    while the heavy ice still lies offshore so strong that no ice breaker yet con–

    structed could possibly get through it, there is a lane of thaw water along the

    land through which a boat of very small draft can worm her way, following the

    beach. Andreasen had purposely built the North Star to draw only four feet two

    005      |      Vol_IX-0141                                                                                                                  
    EA-Transportation. Chapelle: Design and Development of Arctic Trading Vessels

    inches of water, loaded, and in place of a keep l a centerboard that could be with–

    drawn into the body of the ship. He had demonstrated through several seasons

    that he could wriggle along faster than strong whalers could bunt and break their

    way eastward.

            "Andreasen had made no attempt to build the North Star strong, for he had a

    method of which he may have been the inventor, of dealing with the closing in of

    the ice around her. The ship was only about fifty feet long and could turn a–

    round almost in her own length. When he saw the ice closing in and there seemed

    to be no chance of getting out of the way entirely, he would select in the neigh–

    borhood some big ice cake that sloped down to the water's edge on one side. He

    would then steam full speed against this floe. The bow of the North Star was so

    shaped that instead of hitting the ice a hard blow, she would slide up on it,

    standing level because she had a flat bottom. Thus by her own power she was

    able to put herself half-way on top of the ice. The crew were prepared to jump

    out, fasten an ice anchor, and with blocks and tackle to haul the ship entirely

    up on the floe, so that when the ice cakes closed in and began to crowd each

    other their pressure did not come upon the ship but merely upon the ice on which

    she was standing. If this was a solid piece it was likely not to break, and as

    a matter of fact, on the one or two occasions when Captain Andreasen had been

    compelled to use this method the ice selected had stood the test. Later when

    it slackened out and there was a chance to continue navigation, a small charge

    of powder placed in an augur hole in the ice would shatter the cake and let the

    ship down into the water again."

            Recently eastern traders have been experimenting with small double-ended

    diesel-powered freighters, of the Nova Scotia-New Brunswick model. These have

    slightly cutaway bows and canoe sterns; they are single-screw and most of them

    006      |      Vol_IX-0142                                                                                                                  
    EA-Transportation. Chapelle: Design and Development of Arctic Trading Vessels

    carry small steadying sails in either a ketch or schooner rig. The most re–

    cent vessel of this class was about 120 feet in length and was without rig;

    she was built for a fur company to serve as a supply and freight boat. For

    this reason, she does not represent a type that most of the independent traders

    consider useful. Generally, these men appear to look upon a boat of less than

    80 feet in length as best in a schooner, 100 feet in a diesel double-ender.

    The availability of fuel at Hudson and James Bay ports have allowed the use of

    powerboats in the Eastern Arctic trade to a steadily increasing degree. Never–

    theless, many traders prefer some sail power to the out-and-out powerboat, when

    working far from a shore base.

            The Western Arctic traders followed the trend seen in the east; the early

    trading vessels were in the main on fishing schooner models. In the '80's and

    '90's the Alaskan schooner was a sharp, deep fisherman-type hull, rigged as a

    two-master but carrying a leg-of-mutton mainsail. Some of these vessels had

    yacht-like hulls and were built to sail fast. Some three-masted schooners were

    employed but there are indications that the large schooners were found unsatis–

    factory in the ice and uneconomical in the trade. The schooners trading in

    Bering Strait in the '70's and '80's were rarely over 65 feet in length. The

    leg-of-mutton mainsail with a peculiar topsail, triangulare in shape with its

    short side secured to the topmast and its clew sheeted to the mainboom end, was

    very popular and, in fact, did not alter much until the gasoline auxilliary en–

    gine came into use around 1905.

            By the early years of the present century, the Alaskan traders had develop–

    ed two types of trading schooners, usually fitted with auxiliary engines and

    a single screw. One type, the most common among the larger trading vessels,

    was the keel schooner on the model of the Pacific halibut fishermen. This type

    007      |      Vol_IX-0143                                                                                                                  
    EA-Transportation. Chapelle: Design and Development of Arctic Trading Vessels

    first fitted with a bowsprit, came into use in the '90's and had the round

    bow in place of the earlier clipper stem. The noted arctic trader Teddy Bear

    was on this model. Because of trouble with it in maneuvering among heavy ice,

    the bowsprit was omitted after 1905 or thereabouts, and the "knockabout" rig

    (becoming popular in the east) was adopted. Figure 2 shows the lines of a

    typical arctic trader of about 1909; this vessel was built at Seattle, Washing–

    ton. It will be seen that the Western Arctic trader differed in details from

    the model used in the east; these were the type of stern, rudder and aperture

    employed, the deck arrangement and cargo capacity in proportion to dimensions.

    The round stern was very popular in the western boats, though the transom was

    occasionally employed.

            The specifications of the vessel shown in Figure 2 called for a 75 h.p.

    gasoline engine, and accommodations for five men in the forecastle and six men

    aft, two in the pilothouse. Taking fresh water from ponds on the drifting sea

    ice was customary but 250 gallons of fresh water were carried in tanks for use

    outside icy seas. Two large fuel tanks abreast the engine allowed 2,500 gallons

    of gasoline to be carried, giving a cruising radius under power of about 4,000

    miles. The anchor windlass forward was power-driven by a shaft and chain drive,

    operated by the main engine. The vessel had sawn frames and 3-1/2-inch planking,

    all fir, and was sheathed from keel to deck with greenheart, about 1-1/2 inches

    thick. The bow and stern were iron sheathed and there was a plate-strake along

    the load waterline about 30 inches wide. The metalling was with 1/2 inch gal–

    vanized plate. Sails were of No. 6 canvas. A crow's-nest, fully enclosed, 5

    feet high and 5 feet by 6 feet on the floor, was located at the head of the

    foremast. Heavy towing bitts were fitted against the after end of the trunk

    abaft the pilothouse. The deck structures were built very strongly and, in fact,

    008      |      Vol_IX-0144                                                                                                                  
    EA-Transportation. Chapelle: Design and Development of Arctic Trading Vessels

    the whole construction was very massive. Both a hand and a power-driven winch

    were fitted; the latter was driven by the main engine. A small gasoline-driven

    generator was also installed. Heating was done by stoves. The propeller was

    about 45 inches in diameter and 30-inch pitch, three-bladed, made of bronze;

    the shaft was very heavy and oversize for the engine power (3-1/2 inches). The

    rudder post and heel fitting were bronze. Shoe on keel was greenheart. Shrouds

    were 3/4-inch wire rope, set up with turnbuckles. The sail plan was without

    light sails of any kind, no topmasts being fitted.

            Since the vessel shown in Figure 2 was designed, the ketch rig has become

    popular but this entails reduction in sail area and increased reliance on power.

    The introduction of the diesel has increased cruising radius under power and

    reduced the explosion hazards. With more complete dependence upon engines,

    traders have reduced the draft and dead rise and altered the stern somewhat but,

    in general, the model shown has remained popular.

            The deep-draft trader, such as represented by Figure 2, operated in the

    same manner as the whalers, seeking a safe harbor before ice imperiled the

    vessel. If the vessel were caught in floe ice, she was usually abandoned and

    an establishment set up ashore. During the winter months trading vessels in

    winter quarters often had additional deck houses built up, usually enclosing a

    large portion of the deck amidships; these structures were sometimes carried

    during the voyage in the Arctic and not removed until the vessel was ready to

    sail for home. Obviously, the necessity of obtaining a reasonably safe harbor

    before navigation closed was a serious limitation on operations and some traders

    sought to overcome this to the maximum extent.

            It was apparent that more could be accomplished in arctic trade if the

    trading vessel (like the already-mentioned North Star ) were built very shoal

    009      |      Vol_IX-0145                                                                                                                  
    EA-Transportation. Chapelle: Design and Development of Arctic Trading Vessels

    and small enough to be hauled out on a beach. As a result a number of small

    schooners were built, fitted with centerboards and sometimes with small auxil–

    iary engines; these vessels were not only very light in draft and weight but

    also could be operated by a very small crew. When operating in the Arctic they

    carried portable ways and winches that enabled them to be hauled ashore and

    carried up beyond danger from the sea ice. Hence, these small traders did not

    have to seek a safe harbor early in the season but could continue cruising until

    there was actual danger of being frozen in; then only a good beach with safety

    from the shore ice, need be sought, for the boat could be quickly drawn up on

    shore. This class of trader was not particularly well fitted for the long sea

    voyage to the Arctic, so when she once reached the Arctic she remained there

    and operated from shore establishments, or from nearby bases in Alaska.

            These light-draft and small craft were very cheap to build and maintain,

    compared to the regular trader. As a result, Eskimo traders acquired these small

    boats in large numbers and they have gradually replaced the whaleboats once owned

    extensively by the well-to-do Eskimos. Figure 3 is probably typical of the so–

    called "Eskimo schooners;" the boats were light in build and usually lap-strake

    planked with small closely spaced steambent frames. The boats carried but three

    sails, usually schooner rigged, and the minimum of rigging. As can be seen,

    these traders were really no more than large decked boats. With the introduction

    of gasoline engines into the Arctic, these craft have slowly been converted into

    motor launches, many without any vestige of sail power being retained. The usual

    model employed in these boats, when fitted with sail, was one that would work

    very well as a motor boat of moderate power. The shape of the stem shown in the

    plans, Figure 3, the straight keel, the raking square stern and the lap-strake

    construction was to be found in the majority of these boats; sometimes they had

    010      |      Vol_IX-0146                                                                                                                  
    EA-Transportation. Chapelle: Design and Development of Arctic Trading Vessels

    a raised deck forward. With motor power, stability was no longer an important

    matter and the houses were then lengthened and raised to give more comfortable

    quarters. The boats varied a great deal in detail and dimensions but the pop–

    ular size was between 40 and 50 feet in length. Except for occasional use of

    some metal sheathing at the bow, and along the waterline, little attempt was

    ever made to protect these boats from floating ice. Their light weight and

    the care of their crew was considered adequate in navigating under sail among

    ice floes. With the introduction of motors, ice sheathing has become common

    as the speed of the boat under power became a factor in increasing the dangers

    of ramming ice.

            The changes in the design of traders and particularly the trend from auxil–

    iaries to powerboats can be accounted for by the alterations in operating con–

    ditions on the northern coasts of Alaska and Canada. Where, in early days,

    the trader had to be independent of bases ashore for long periods and so almost

    entirely self-contained, now the increasing number of shore establishments be–

    longing to the fur companies and United States and Canadian governments make

    obtaining fuel and supplies in arctic waters possible and so permits the use of

    craft that are not self-contained in all respects. To a great extent, therefore,

    the modern trading boat is a small power vessel or launch, of light draft and

    strong construction, fitted for a very moderate cruising range and with more

    space given to the comfort of the men manning her than was to be found in earlier

    traders. However, where operations are still carried on far from shore bases,

    the small auxiliary trading vessel is in use; the need for low fuel consumption

    under such a condition make the employment of some sail power almost mandatory,

    even today.

            The arctic trader, like other commercial vessels operating under dangerous

    011      |      Vol_IX-0147                                                                                                                  
    EA-Transportation. Chapelle: Design and Development of Arctic Trading Vessels

    conditions of navigation, must be a compromise between the factors of economy

    of build and operation and those of safety in the area of performance. The

    problem, then, is not of producing the best and most complete boat or vessel

    for arctic operations alone; rather it is to produce an economical craft, to

    build and operate, that will be reasonably safe in the arctic seas. To do this,

    there could not be reliance upon any system of maintenance and repair establish–

    ments ashore, for these would be too expensive to maintain and operate within

    the economic limitation of the trade. While making many concessions to the use

    of mechanization in these vessels, the traders preferred to rely upon strong,

    simple, and reliable engines and gear in preference to the use of complete, or

    automatic, operating machinery. The aim was to employ only fittings and gear

    that would be good enough for the work, and no more, in order to keep costs

    within the firmly established financial limitations of arctic trade. During

    a trading voyage, it would be fatal to a profitable venture to have to spend

    time in repairing or replacing machinery not absolutely necessary in the primary

    functions of a trading vessel or boat. This is made apparent when the modest

    size of the craft best suited to the trade is considered, as well as the simple

    organization and small financial returns characteristic of the independent trad–

    ers. Even the well-established fur companies must operate along these lines,

    though their trading posts may permit the use of one or two large supply ships

    or freighters, as well as some small craft.

            Until engines and machinery can be built that will be low in cost and cap–

    able of operating over long periods without constant care and attention under

    the most severe conditions, mechanization in small trading craft in the Arctic

    must be relatively modest. The manner of life of an arctic trader makes him

    unusually self-reliant and this element in his character undoubtedly influences

    012      |      Vol_IX-0148                                                                                                                  
    EA-Transportation. Chapelle: Design and Development of Arctic Trading Vessels

    his choice of vessel and fittings toward simplicity, reliability, and primary

    usefulness rather than placing emphasis on "labor-saving" devoices, such as

    automatic operation supposes, or upon matters of engineering efficiency alone.

    His idea is to obtain a vessel that will transport his crew and goods without

    the need of special attention and without breakdown, wholly reliable, reason–

    ably self-contained if that is a factor in his operations, and low in cost,

    yet suited to arctic conditions. This ideal has yet to be attained in full

    but was probably approached by some of the older trading craft, which makes

    their study worthwhile in an examination of arctic shipping.
