Re: CS36T - Deep vs Shoal Keel Questions From Potential Buyer
I also have the shoal draft (4'92) and have recently sailed her in fairly steep 5-7 meter waves. This is definitely a boat where you'll feel very safe in nasty weather due to the heavy displacement but also how she handles those waves.
In fair weather I can do 5-6 knots reaching even in 7-10 knot winds, 4 knots in 5 knot winds, (although I do have a VERY lightweight 150% Genoa which helps). She doesn't start heeling beyond 5 degrees until 23 knot winds even with full main and 150% Genoa, only reaching 30 degrees heel at 30-35 knots with everything up at which at which point the helm starts getting difficult. You want to start reefing/changing sails between 25 and 30 knots. I find I rarely switch out the 150%, it's ridiculous.
She's slightly slower on runs where she prefers to keep the wind/waves on the quarter and the stern is beautifully angled for that.
Waves under 3 meters seem to be irrelevant, she just slices through them slowing only slightly at crests, it's very easy to keep up momentum - which makes jib trimming/backstay adjustment easy or unnecessary unless maybe you're racing.
Best point of sail is definitely close hauled. Sails are super easy to balance and she sails so straight even on a beam reach, even with 2 meter waves you can sit back and relax and you won't be using the autohelm/vane except on runs. Makes it easy to cook or go to the head.
Hope that helps!
