If i want to get more rake in my mast is it class legal to get another chain plate or do I need to get an extended forestay? If so how long does it need to be and where would I purchase one?

I used a 10 hole adjuster up front, which allowed me to use the bottom hole on the side shrouds, that allowed more than enough rake to go block to block.

It seems all the stay wires are of various lengths.., never know what they were smoking out there in California when they were putting them together.

I use a 10-hole chainplate adjuster. In doing so I had to take off the side adjusters and just use shackles. Otherwise the rig was too loose.
I can go block to block, but rarely do. Also,my Calvert mainsail has four holes to select from, so I can put the hook into one of the upper holes.

First I have heard that the wires vary (production can vary slightly)... would have to be referencing similar model and year of production of course. SE and Club and years of production could vary.

I am more inclined to look at the differences in hulls. These are plastic and do deform under loads. Bows at varying widths / height at the tang point would result in differing bridle / forestay / rake outcomes.

BTW... we don't allow smoking in the metal shop.

Just kidding, Matt, although that has been a on-going comment ever since I started sailing Hobies in 1980 when I got off the Tornadoes.., thanks to Carter.
