"The Amphi-Craft was to be an all-purpose boat having wider appeal and a more affordable price than most Herreshoff Mfg. Co. boats. Although the design was aggressively advertised ..., only fifteen boats were built. They were elegant and, for what they were, rather expensive.
Two of the boats are known to have been preserved (#1276 at the Herreshoff Marine Museum and another at Mystic Seaport [#1388s]), and they show some features worth knowing about. For example, the mast is in two piece so that it will store inside the boat, the wishboom rig holds the sail in its most efficient shape, and the rudder is pivoted to kick up in shallow water.
Although the Amphi-Craft hulls were built upside down, as was the Herreshoff custom, the shop's method, used for the larger craft, of bending the frames directly over the molds gave way in these and certain other small craft to ... a jig-type setup in which the boat's frames are bent over ribbands sprung around and fastened to widely spaced molds. This system requires less lofting and allows the intact jig to be left undisturbed, boat after boat; it has long been a favored method among other builders.
Except at the bow, this boat's frames run continuously side to side across the keel and are held at each end by turnbuttons at the sheer. ...
Sidney Herreshoff designed not only the Amphi-Craft but also a special trailer to go with it. The Herreshoff Mfg. Co. built the trailer as well as the boat, using running gear purchased from the Indian Motorcycle Co. and a steam-bent, varnished oak frame complete with the Herreshoff Mfg. Co. logo hand-lettered in red paint. ..." (Source: Bray, Maynard and Carlton Pinheiro. Herreshoff of Bristol. Brooklin, Maine, 1989, p. 190.)

• Note: The vessel index cards comprise two sets of a total of some 3200 cards about vessels built by HMCo, with dimensions and information regarding drawings, later or former vessel names, and owners. They were compiled from HMCo's early days until 1920 and added to in later decades, apparently by Hart Nautical curator William A. Baker and his successors. While HMCo seems to have used only one set of index cards, all sorted by name and, where no name was available, by number, later users at MIT apparently divided them into two sets of cards, one sorted by vessel name, the other by vessel number and greatly expanded the number of cards. Original HMCo cards are usually lined and almost always punched with a hole at bottom center while later cards usually have no hole, are unlined, and often carry substantially less information. All cards are held by the Francis Russell Hart Nautical Collections of the MIT Museum in Cambridge, Mass.

A comparison of the two transcriptions can be particularly useful in those many cases where the handwriting in the Construction Record is difficult to decipher.
