So much so that I had to support both legs on a coaming, sitting sideways on the cockpit seat, and pull with both hands on the tiller like I was deadlifting weights any time a puff came along. It was always known for being hard to steer with an amazing amount of weather helm when beating in a breeze. Our boat has a longish keel with an attached rudder. However, for anyone contemplating giving up and just going with poor tune, I would like to share some encouragement: That’s what it felt like the first time I did it too. Seeing this whole process written down in an article does make it seem very laborious indeed. Also make absolutely sure you have rake and prebend right since you say the aft port side of the partners is the problem, therefore less rake, or more prebend, might also have a positive effect by moving the mast forward at the partners. That said, before doing anything, I would recheck everything you have done so far, starting with the first chapter of this guide, to make sure there was not an error in levelling the boat or setting up the mast. Far from ideal, but I think the best of the three options. I guess, if it were me, and I did not want to take on fixing the boat, I would lean the mast a bit more to starboard to produce at least 1/4″ of clearance to port for the spartite with the mast straight athwartships and rake and prebend where you want them. (Carbon masts require at least 1/2″ of spartite cushioning at the partners) Also, I don’t like the idea of having the mast hard up against the partners, although I guess it’s the lesser of too evils, as long as it is not carbon. This is a highly loaded part of the mast and I think there is a risk of stress cracking if you do that. I really don’t like the idea of inducing a bend at the partners to compensate. The right way to fix this is to determine whether it’s the step or the partners and then fix the core problem. The only other thing I can think of is that there is a big wow in the mast low down, which is throwing things off, but I assume you have checked for that? Yikes, it seems that either the step or partners are badly out of true. This is why it is common to see performance multihulls beating in heavy air with a small jib hauled out slightly to maintain slot, eased traveller, and a tight mainsheet. A small jib upwind is also a common solution, since it is hard to maintain a tight forestay. Thus, playing the traveller or reefing are better alternatives than a loose, twisted main. Ease the main in a gust and the jib instantly becomes more full due to forestay sag, defeating part of what you were trying to accomplish. Forestay tension comes almost entirely from mainsheet tension. Thus, it is common to over rotate off the wind and under rotate beating in heavy air.ģ. Second, rotating the mast pushes cloth into the center of the sail (prebend pulls it out, but a rotated mast is straight), increasing draft. First the cord of the mast section is added to the draft. If the mast rotates, this can have major impact on draft for two reasons. Mainsheet tension may have some effect on fractional rigs, but it is minor.Ģ. Mast bend comes primarily from raked diamond wires. My experience has been mostly with mutihulls, which like B&R rigs, have no backstay and generally no vang. A few thoughts that may have been in there, but I missed them.
