Kenjamin, I've tried to be supportive about your boat. . . . .
. . .but you've got serious delusions of grandeur if you think you've just invented the new ultimate sailing rig with that curvy mast! One test sail in "just perfect" conditions does not answer all of the questions and issues that remain with this experimental rig before somebody starts mass producing them! And writing you royalty checks?!? There are a whole bunch of things about this rig in contrast to the conventional CY rig that have yet to be answered to my satisfaction before I could allow that this is anything other than an idiosyncratic, custom answer to your personal requirements of a) keeping your stowed mast out of the way of your fishing buddy and b) being unconventional. I maintain that the original and conventional CY rig is simply better and certainly more user friendly than your custom rig--even, or in fact especially, for a boat that is going to regularly hoist and strike her rig while afloat.
Mast structure:
How much heavier is that complex and noticably taller mast than a simple straight birdsmouth spar? How much harder is it to step in a seaway while afloat, rather than at the dock, than that shorter, lighter mast? When you pick up the curved mast doesn't it want to rotate in your hands to put the unbalanced, heavier side down? A straight spar doesn't do that. How much longer did it take to build and how much more does it cost than the proven spar? How easy will it be to get a replacement if you break it? Isn't there a stress riser where the boom intersects the spar right where the curved section goes straight again, and how well will this hold up over time in other than "just perfect" conditions?
Mainsail issues:
The luff of the sail fits in a luff slot in the back of the mast--how easily does it slide up and down? Will it come down on its own, or do you have to pull it down past the curve? How long does it take to feed the luff up into the slot when hoisting sail? Is this something you can do with only your own two hands, or do you need one person to feed the luff while the other hauls on the halliard? (And then who is steering?) Is this something you can do while seated, keeping your weight down low and centered, or do you need to stand up to reach it? How well will this work when the conditions get rough, when the sail is flogging around partially hoisted. How much longer does it take to do all this than the literal 45 seconds it takes to haul up a lugsail, tighten the downhaul,and sheet home? Furthermore, how quick and easy is it to tie in a reef--and can you properly flatten your sail out when you do this? Will your sail come all the way down while you are fiddling with reef points and clew outhauls and such, or will it be mostly still up there, flogging in the wind and driving you to leeward. How easy is it to stow and unstow all this stuff-- your bundle of sail with its battens and little gunter yard, your boom, your curvy mast--and how long does it take to go from everything down in the boat to everything up and drawing? I guarantee it takes substantially longer than setting up the balance lug.
Jib issues:
Being able to change sizes of jibs can be useful to adapt for the conditions in larger boats--but going out all the way to the bow to change the tack isn't so friendly on a small boat. Two extra sheets to tangle up and stow--per jib--unless you're also going to change over the sheets when you change the jib--taking even longer to set up a sail change--and you'll still have to change your sheet leads for the different size sails. How well does your curved mast take the pressure from the jib's luff tension and how much will the luff sag off as the wind builds? Are you going to add backstays to counter this? Backstays also take a while to untangle and set up for a rig you are setting and striking regularly.
Performance issues:
You say that your boat pointed higher than Patina. This may be--though I'd like some independent verification of this. (Owner of the lovely Patina, where are you? Come post on our forum, please!) Were you actually sailing side by side, or is this your memory of first sailing in one and then the other? If you were sailing side by side, who was faster? Who was handier in stays? Who was first around that buoy? It is certainly possible that Patina did not point as high as Xena, she may not be set up optimally yet--she could have an inefficient CB shape, or sails that weren't cut right, or tweaked properly. It could be that her helmsman was relatively new to sailing, or to the rig itself. The thing is, I myself, and other performance oriented sailors with racing backgrounds and experience like our friend Boatmik have been able to get very good performance out of lug rigs, upwind and down. I can point as high in Rowan as any sloop with a jib set flying, and the windier it gets, the higher I'll point in proportion as that jib luff sags away. (Pinching super high isn't always the fastest way to get somewhere uphill, by the way--sometimes it is better to fall off a little bit to make up in increased boat speed what you lose in heading--but I digress.) Again, I would say that one sail in "just perfect" conditions doesn't tell you all that much about the performance of the rig overall unless you are going to restrict your sailing time to "just perfect" conditions.
Aesthetics:
Not my cup of tea--though I will be first to admit that beauty is in the eye of the beholder.
Kenjamin, I'm glad if your boat pleases you, but I think you are steering people down an errant path by promoting your rig over the conventional CY rigs for most people/most conditions. The ease of building and set-up and performance characteristics of the conventional rigs are tremendous. Yours is complicated and cumbersome and has yet to have sea trials in a wide range of conditions. I would love to see an evaluation of my questions and issues from an independent source, someone else with lots of sailing experience in small, open boats--but until they are resolved I must protest!
Good decisions are gained with experience, which is gained through bad decisions. . . . . .
