Mark,

Thank you for your careful reply.

Not being familiar with rod rigging, how do I know if its OK or needs 
replacing ? I know I can ask but that still leaves me in the dark and 
unsatisfied  :-)  Besides, there are no other boats with rod
rigging where I am hauled, its uncommon down here, and I might be taking 
advice from someone who has a hidden agenda, as in sales  :-)

On page 6 of 7 of the 1990 Carroll Marine Sales Brochure and Spec Sheet, 
which is on the frers33 website, wing keel is listed as 4' 11" and the 
draft as 6' 3", which I assume means that the wing keel
was an option and reduced the draft by 16", which appealed to me in that 
my primary intended sail area is the Caribbean, though I must say I'm a 
bit dismayed at the prospect of being the only wing
pilot  :-)

Anyway, if you could provide the referenced "keel offsets", I'd be most 
grateful as I may decide to later go that route, if not now.

Cordially,

Courtney
