Re: Stus-List C 30 Shoal Draft

[Michael Brown via CnC-List]

PHRF-LO lists the 30-1 draft at 5', and the shoal draft version at 4' 2".

Though the manufacture's displacement specs are usually optimistic,
the shoal draft version is claimed to be 500 or 600 pounds heavier.
I would guess that the extra weight, possibly extra waterline, is not as
much of a handicap downwind as upwind.

In light air there is not much leeway, the deep keel should be better
than a shoal draft keel but there may not be much difference.

In moderate air the deep keel is suppose to generate more lift with
less leeway, but also has more drag.

It appears that there are differing reports from the literature.  
Sailboatdata.com has the draft at 4.2' for shoal and 5.00' for standard.  In 
any case, it appears that the shoal is somewhere between 4'3" and 4'6" and that 
theory holds a bit in practice of the owners, but the shoal still points well 
enough (although not as good as standard as would be expected) and sails to its 
handicap.

Re: Stus-List C 30 Shoal Draft

[Antoine Rose via CnC-List]

Hi Graham,
I do have the shoal draft version (4’ 3") and race it every Wednesday in our 
club where there is another C 30 with std draft. Yes, he does point higher 
than me for two reasons : deeper keel and his boat is more recent with the 
shorter mainsail and a track for the genoa block sheets. My sheet blocks are 
hooked on the rail, meaning the sail is not trimmed inside as close as his, 
decreasing the ability to point. That said, despite the fact he has a 150% 
genoa while mine is a 135%, I’m always faster than he is on downward legs, 
thanks to shallower draft (less wetted surface) and thanks to the larger 
mainsail.

Antoine (C 30 Cousin)

Stus-List C 30 Shoal Draft

[Graham Young via CnC-List]

Good morning fellow C owners,
I'm looking for input from those who have sailed the shoal draft version of the 
C 30 (draft of 4'2") in comparison to the standard draft version (5').  
Theoretically, the standard version should point a little better, but in 
practice is there much difference in performance and sailing characteristics?
In terms of base handicap on Lake Erie, there is a 6 second difference (183 for 
shoal draft versus 177 for standard).

Also, does anyone know whether C ever made a deeper draft version of the C 
30?  There was a 1976 C 30 for sail in the boatyard next to my boat this 
spring and the keep was deep and definitely not the 5' swept back keel 
characteristic of the 30.  Sitting next to my 32 on the cradle, it appeared 
every bit as tall and I kept looking at it in puzzlement.  The ad for this boat 
on yachtworld said it had a draft of 5'10".
Thanks,
Graham
