Ctrich (and the group):
You're asking three different questions...but first, for your boat (CT 41) don't overlook the fact that the genoa track attachment needs to be at least as strong as the mizzen's gooseneck if indeed you are worried about 'extreme sailing conditions'. Typically, this means the gooseneck assembly needs to be welded substantially onto a car that rides on the track, which in turn is mounted to the spar. In my case, my mizzen is only 100 sq. ft., perhaps 65 sq. ft. when reefed. That can generate a lot of 'umph!' in a heavy blow but in reality it doesn't require a massive gooseneck nor track attachment. Your boat is I believe different, with more sail area in the mizzen...so look carefully at the track attachment issue if you really do anticipate heavy weather
Re: your first Q, I'm assuming you will lose about 10 sq. ft. of sail area if raising the boom...and on a sail that you may not even use on certain points of sail. (I multiplied 13" x 10' of mizzen boom; if the boom is 12', it would be 12 sq. ft. - in truth, not much). Change in CE would be irrelevant. So...how significant is losing 10+ sq. ft. of a sail back aft, when the whole sail gives you zero drive to weather
, little drive on a close reach, and where you should be looking to sail changes (adding a mizzen staysail) in light-medium winds from a beam reach on up? Can we not assume it matters little? Can we give up on the idea of a new $$$ main with a fuller roach? Given your boat's HUGE wetted surface, you are not going to miss 10 sq. ft. from that mizzen, IMO - save the dinner & beer
for your sweetie, not the sailmaker
Q2: Should you be concerned about increasing the distance between deck & boom. I sure would think so, as that CT 41 cockpit
has you out there working without a net, dancing around in a blow while trying to tie in a reef. The last thing you want to do is impersonate a ballet dancer, on your tippy toes, while tying in a reef while a big swell is running. If you can't comfortably, securely reef the mizzen at the boom's new, higher height, then release tension on the halyard
, pull the pin in the track on which the boom rides, and drop the boom so you can better reef the sail. You want to insure you have stout fixed stop at the bottom of the track (not one of those plastic track stops); in heavy conditions, this would be harder to do than to describe.
Q3: Added pumping in heavy seas? I doubt you'll find any meaningful changes from a *smaller* sail that you then raised 13" but otherwise made no changes to? It sounds like your expecting substantial change to result from a relatively miniscule change in sail plan.
Where is this heavy weather going to be found? Where are you and what are your sailing plans?
