What a Dilemma!!

Dan, do you have a pic from Blonde Starnger's keel??? There are only 13 boat
from Renata to Blonde Starnger, and both are 1981 models..



Renata's keel with skeg is the most different one that I have seen.I've been
collecting pics from C38's for sale, because Estancia was such in bad shape
and modified when I bought it, that I needed lots of pics in order to tell
what was original and what wasn't, and of course to get tips from other
 boats..

Tom, I'm going to put a production change on the table for the following
reason:

The  silhouette on the original brochure does shows a slightly larger keel
trunk, and one of the most notable differences is the back edge of the keel
(just forgot the technical name!) is perpendicular to the water line. Let's
call it straight!!!!  The deep keel version is angled, even if the keel
draft has been reduced, you'll be able to tell because of this, but if you
look at the attached pic from Chute the Breeze or the other one I sent a
couple of days a go, it looks just like the shoal keel on the brochure,
straight down! without an angle, that's why I always tought that I had these
pics from shoal draft versions!


One more thing, Estancia is 1982, and came with the 1982 brochure (which is
older than the one on the C38 web), and shows no  skeg either.

My opinion, evidence shows two shoal draft versions, so who will be able to
confirm a production change???????????
Just found another  shoal draft pic on Calatlinaowners.com, has been
attached also..

Tom, there is  a known cure for the loss of a C38, but it requires lot's of
money in order to get a newer and bigger boat!!!! Just make sure that this
boat is faster than a C38, other wise, not worth it....LOL

Max
