Re: [Amel] going to weather

Kent, save yourself the trouble, you will reach the same conclusion as we did when we tried “inside the shroud” sheeting of a blade type 100% jib.



I used three boom vangs and connected the bottom parts to the kick strap shackle at the base of the main mast, the u-shaped tack point for the mizzen staysail/ballooner, and the “ear” weldment on the vertical stanchion that you tack the main boom preventer to. I joined the three vangs at “the top” onto a snatch block with the sheet from the headsail in it. This way I could triangulate the lead to put the block where it allowed the most efficient shape for the headsail when pinching up to weather.

Maybe a couple degrees better windward performance in mill pond flat water, but the previously mentioned beautiful big fat keel would then abruptly stall and all was for naught. It chop, the boat would stop and fall off, albeit with a perfectly trimmed but abused headsail!

The bottom was clean, the leading edge of the keel was fair and smooth, but this keel quits ‘flying’ dramatically and suddenly when pushed where it doesn’t like to go.



All the best,

Thanks, Dave. If I was to try the barber-hauler, where would I attach it inboard? I'm guessing that the idea is to get a better shape to the jib by bringing the clew in and easing the sheet a bit?

Kent,

Bringing the sheet inboard on a masthead rig like ours is not going to hurt the performance of the main. You may get a bit of a bubble but the boat will still be sailing higher and faster. Joel brings up an excellent point about the keel being a limiting factor. You definitely don't confuse the Amel with a Farr 40.

One of the issues with the smaller headsail is what do you do for downwind if you're using the twin poles. Obviously performance would suffer a bit with the smaller genoa. The best answer in my opinion is to join the balooners together with a common luff and fly them from a foil-less furler.

You guys ought to change the subject line when you change the subject…

Lots of experimentation has shown that, after a point, the limiting factor in squeezing up to weather is the keel. That big fat beautiful keel that contains all the fresh water and the bilge sump (and is much stronger in a grounding than more performance oriented “skinny” keels that intersect the boats bottom at 90 degrees) is not very efficient and stalls quite quickly when pinching to weather. The 110% Caribbean Blaster blade jib from Super Sailmakers and similar sails like the good one Dave’s company makes really help as they provide better lift without pushing the bow down with too much raw power. The high clew is easier to see under as you steer while listening to your crew scream bloody murder from the increased angle of heel and ‘boom-splash’ as you bang your way to your destination. You can use barber-haulers to bring the sheet lead inboard and this will discourage one from mounting permanent hardware as the cost/complexity/leak
potential is frankly not worth it.

By contrast, the new AMEL 55 has a much more performance oriented keel with a thinner genuine lifting foil section and more of a bulb than the wings we are used to. It has no room to carry the fresh water as before but the boat points higher and foots much better. You can feel the stall approach, like on a Lazer dinghy, and play the stall sweetly with the much more efficient rudder that is mounted much further aft than ever before. The difference was startling to me after having sailed every AMEL big boat from the Meltem to the Mango, Super Maramu, and the 54. Much better performance on every point of sail but I’ll also miss that water tank…

The young guys at AMEL are starting to refer to me as ‘The Geezer’ for my reverence with what came before.

All the best,

Joel
