Ugh!
I remember when that boat came out and attaching the forestay in the anchor well left me cussing.  One evening, I tied a rope,oops I should have called it a line and went down into the woods to partake of the local finest water from my next door neighbor.  Customer sneaked up on me the next day and I had some explanation but with a sever impairment frrom the night before sippinon moonshine, I had some tall explaining.Peter, on the serious side, You might want to do some changes for the forestay.  Purchase two stainless tangs or long metal straps and secure them to the base in the anchor well.  They need to be long enough to protrude just above the anchor well. To keep them seperated a little, use a pin or bolt just below the top clevis pin attachmentand use several washers between the tangs and tighten.  shorten your forestay and use for example a norsemanswagless terminal fitting which will fit onto the turnbucle.  The bottom of the stud of the turnbuckle should be attached to the top of the two tangs just protruding above the anchor well.On the 240,23.5, 260, etc., there are no backstays which make it alot easier to pull the mast forward using a block and tackle for example the mainsheet.Jerry mentioned using a quick release shroud lever on the split backstay which would release tension and that is a good idea. I realize it may cost a little but hopefully, these suggestions might help you.   Good luck and thank you for your imput in the past.One other thing, check the wheel bearings and fender attachements if you have a KWS or Ken's Welding trailer.  Also, if you do or do not have brakes, do not go over 55 or you will feel the trailer swaying if only one axle.  If for any reason should the trailer start to whip, speed up a little to stop the swaying and then back down slowly if there are no brakes.Happy sailing my friend from Crazy Dave
