Re: Full or fin keel?

Still, there have been modifications applied to full keel boats that improved function such as those using Henry Sheel's work or the keels with a gap in the middle which I recall were done by an englishman who's name escapes me. Unlike the Brewer's bite or cutaway forefoot the basic integrity of the design element was intact. In some respects it's unfortunate improving full keels was not further pursued.One can think of a vessel employing what we now know about attached flow/parasitic drag, tip vortexes but still having an true full keel with attached rudder. With current materials might be easier to build a very strong boat with little deformation from rig loads and reasonably shoal draft given the basic form.
