:shock: I have H17 and I am thinking to make it stiffer by adding the jib spreader (even I don’t have jib). Any idea how to fix it between hulls?
Presumably you have some concerns about the overall rigidity (?) of your boat, and thinking a forward spreader might help. Am I right?
There is some discussion of stiffness on this forum. Much of it centres around the connection of the hulls and cross beams. I don't recall mention of a spreader in that context, mostly it's about castings, beam ends and "goodness of fit" between the boat, beams and castings. My school-boy physics tells me that the spreader will hold the bows apart, but won't do much to stop the boat twisting, if that is your concern.
I have yet to pull my 17 apart, so I don't feel qualified to make too many suggestion. But there is a lot in the forums -do a search and see if that might be helpful.
