[frers-list]Fairing keel and rudder

[Rod Stright]

If you don find out who modified it sail it, I assume it will be fine, you
may have to reef earlier that the rest of us but if you are cruising you
would want to anyway.

Art,

My boat IS -->  #54,   but has no horizontal "wing", just the bulb, 
which does have "some" horizontal aspect to it, but not what I'd call a
wing. But maybe Frers or Carroll Marine, through testing, felt that the
33 was adequate without a pronounced wing aspect. Dunno. My boat is the only
one of which I'm aware with the factory built shallow draft but would sure
like to hear from anyone else that has this keel.

The 40" measurement I previously gave was not from the waterline, but rather
from the keel-front-hull-entry-point to the keel's bulb bottom,
so....perhaps mine would measure about 4' 11" from the waterline. I'll make
a rough measurement next time at the boat. So....maybe I'm not in 
as dire straits as feared  :-)   I assumed the draft was from the 
waterline but was not sure from what points others were measuring their
keel/rudder lengths.

I wanted the shallower draft but, as I said, am not sure if it has been
altered and even improperly so.

I have assumed that since less keel depth produces a shortened lever arm,
that, my boat (#54) would have required a serious bulb for ballast
compensation for the lost keel mass, (as opposed to Oz's picture of the
unadorned Relentless keel); as well as a more winglike profile than #54
has... for enhancing lateral stability, but I'm no NA.

Wonder if Carroll himself would remember this boat's keel construction,
since it was possibly one of a kind............

Most gratefully,

Courtney

with fairly large wings. It does sound like yours was an after-market
modification.

Bill Thompson did it the right way engaging Mars Keels and adding more

to go back to the owner who made the modification to find out what was
really done.
