Philippe, a few questions...
Philippe, you are so kind to share your experience. As far as I can tell, you are the only person fearless enough to make these additions for heavy air sailing and push this boat to it's limits. I'm still trying to understand exactly what you did so I can try to be as brave as you. A few clarifications would be most appreciated.Regarding the hiking straps:1) You attached the foreward end on each side to the eyestrap for the sheet bag. I would assume these eyestraps were not intended to take a load so probably are not backed with wood or plates. Have you found that they are study enough attachment points or did you have to reinforce them? How much do you weigh? I assume you connected to them using a shackle?2) Could you instead have used the chainplate on each side for the forward attachment? The advantage is that these will take tremendous loads. Also, when I'm singlehanding, I'm always sitting aft of these.3) I'm not clear on aft attachemnt - are you saying you attached to the rear cleats on each side? The rounded seat back just in front of the cleats is in the way - do your straps pass above this or in front of this (ie, to the midline of the boat)? Do you have two separate straps or did I understand you to say that you have one strap which loops around the aft cockit through the aft cleat on each side? What is the advantage to looping it rather than having two independent straps? 4) When you say "hook in" do you mean with your feet or do you use a harness? Do you use the hiking strap alone when single-handing the boat?Regarding the trapeze:1) Do you attach to the tangs just below the spreaders or did you add new tangs for the trapeze? If you used the existing tangs, did you do this by adding a shackle between the tang and the existing wire stay and then hooking the trapeze wire to this shackle?2) How long is the trapeze wire - does it terminate well above the level of the chainplate or does it get close to the chainplate?3) Are you saying you've hooked the two trapeze wires together via bungee cord through the line-pocket eyestraps? If so, why so far forward; why not use the chainplates instead?4) In heavy winds, are you able to use the trapeze alone single-handing the boat or is it used only by a crew member? If you can single-hand with it, did you find the filler extension long enough? Regarding the mast rake:The forestay is fixed length. Did you rake the mast back by adding a shackle above or below the roller furling and/or by tensioning the upper wire stays? If you added a shackle, was one shackle enough to get 10-15 degrees of rake?Regarding sail trim in heavy air:I'm going to add a cunningham as you suggest. However, I'm curious how you trim your vang for heavy air. Do you ease the vang to add twist to depower the sail or do you keep the vang tight to minimize twist and fight the gusts and a powered up sail just by easing the mainsheet?If you have any pictures or a drawing I would love to see what you've done in better detail. I appreciate very much your sharing your experience with me and others. Good sailing!
