Especially "Pylons are now different too. A seperate extrusion. A teardrop shaped tube with no luff track slot in the back."
That is one less place to have to seal shut with silicone or expanding foam.
By the way- I may have mentioned this on earlier posts: we used to fill our side and crossbars with expanding foam, and pull the corner castings and fill the pylons too. This added very little weight and kept water out. Think about how much water can slosh around in the tramp frame. I think it aided in righting the boat too because the entire trampoline frame and supports had floatation in them. I learned the trick from a Worrell 1000 participant- which is where my 16 earned it's sea-legs.
If you do this, be careful how much expanding foam you use. Use a 4 foot length of clear tubing fitted to the nozzle. Insert as far as possible in one end and squeeze the trigger while withdrawing the tube at a fairly quick pace- repeat on the other end of the bar. Stand back and watch the foam profile of your rails grow out of each end.
Cut off excess when dry. Reassemble and enjoy.
Um- this isn't like not class legal or anything is it Matt?
