Speed dating the deep hull

When first developed, these boats had large keels to support them when sitting on the mud flats, causing them to be slow in light airs due to excessive wetted surface.

They quickly acquired a reputation as good cruisers as their shallow draft and seaworthiness are features at the top of any cruising man's list.

Too far forward or too far aft and the resistance will dramatically increase. The deep plunging of an ordinary hull is avoided by the stabilizing action of the fins which are also very effective in dampening out rolling motions.

The fins also provide a certain amount of lift to the stern at speed when the hull is upright.

here has been a growing interest in twin keel boats in North America.
