A 20' 11" Auxiliary Banks Dory
By William & John Atkin
A Banks Dory with Motor and Sail
The dory, for its size, requires the minimum amount of lumber, fastenings and fittings and has very few (in comparison to the usual steam bent or sawn framed battened seam hull) separate parts. It is a strong structure, reasonably light in weight and long-lived. At speeds in the neighborhood of 8 m.p.h. or less a dory is an easily propelled boat, and with most modest power. In view of the fact that most Banks dories are pulled (and often pushed) by oars, the model has been developed to a wonderful degree of efficiency, and the ease with which they move through the water is astonishing. From the viewpoint of seaworthiness the old fashioned narrow stern dory rates exceptionally high. This is not to suggest that other types than the above are not well worth while; they are, but it depends upon the use to which the boat is to be put that decides its suitability. And so it must be remembered that there are, what one of my old clients calls "sissy" boats -- and what I call wholesome practical boats. In the latter class I list the dory, the Seabright skiff and the double-ender. And now we come to this month's design -- Pemaquid, a Banks dory with motor and sail.
She is laid out in the most simple manner and rigged with a single mast and standing-lug sail; no stay, no shrouds, a single halyard, and what might be named a rope traveller -- a piece of running rigging made fast to the yard above the point of attachment of the halyard and leading around the mast, thence to a cringle made fast to the yard well below the point of attachment of the halyard. This piece of rigging extends to the thwart and when hauled taut holds the yard against the mast. In lowering the sail this line is cast off. With a rig of this character it is easy to unship the mast and carry the whole thing ashore. The sail area, by the way, is 78 square feet and the sail should be made of canvas no heavier than 4 ounce.
The overall length of the dory Pemaquid is 20 feet 11 inches; the length of the bottom 16 feet; the breadth 5 feet 7 1/2 inches; and the draft 1 foot 5 inches. The freeboard at the bow is 3 feet 1/4 inch; least freeboard 1 foot 7 inches; and freeboard at the stern 2 feet 8 1/2 inches. Therefore she is a sizable boat. Unlike most dories this one is fitted with a long straight shallow keel and carries on this 225 pounds of lead ballast. It will therefore take a lot of bad weather to bother her stability. The sections above the bottom are all straight; the keel is straight athwartships and carries little curvature fore and aft. Therefore there are no compound curves or other difficult curves to contend with. The lively sheer line coupled with the wide flare of the topsides is a well worth while feature and a great saver of lumber as well as of time required for the shaping and laying of the four topside strakes.
For power the plans show a single cylinder 6 h.p. Baby Huskie Palmer motor. This is installed at a point slightly forward of amidships and will be covered by the center thwart and the box, or housing, as indicated. The speed under power of the little packet will be a good 7 1/2 miles an hour.
