Re: Full or fin keel?

Wolf,

Curious, is your B/D only using the "lead" in you keel? if so, you probably have a higher % than that, as one "should" IMHO include the rest of the keel as ballast per say. A swag would then be 4500lbs/15K = 30%. As you really have what is a precursor to todays T keels, but do to materials and knowledge of some material strength, many things were designs heavier than need be. With what is probably a 5'long, 6"wide, 1'high chunk of lead at the bottom of your keel, it behaves like a heavier fin keel from a stability point of view.

my 01 on the subject.
