I'm about to glue my Hobie 16 so I'm taking some measurements before I take it apart. When I measure port bow to starboard transom it’s 2 inches shorter than starboard bow to port transom. How to I square them up? It’s not moving easily.

Loosen the tramp completely. Use a 2:1 line system to pull the long measurement.

Bob,are you glueing just the pylons or are you also gluing your side bars.Check out this site.

Jan Gougeon (West System) was up here in Thunder Bay racing Dn's at the North American,s.He would be a good guy to talk to.

DO NOT GLUE THE SIDEBARS. The sidebars are not structural.

Talked to a couple of guys at the N.A's and apparerntly they glued there side bars,seem to stiffen up the frame.My boat is very squeaky from the side bars corner castingings connection.

Just because other people do it doesn't mean it's right or good for the boat.

By gluing the sidebars, hard points are created that focus stress on the weakest part of the castings (the sidebar sockets). Eventually, they'll break. Ever try replacing a broken casting that's been glued in all three sockets? Not fun.

Besides, any "gains" achieved by gluing the sidebars are easily lost by bad boat handling (missed tacks, bad surfing techniques, over steering) or poor tactics and strategy.

I have suggested that a softer adhesive might work to limit the squeaky sidebar issue. Maybe try a bit of 3M 5200 rather than epoxy. I would inject somehow after the tramp in tightened. This would dampen the motion that causes the squeak.

Good sugestion Matt M.Any suggestions on how to get the 5200 in there while tramp is still together.

Not looking at one now, but there is a bit of gap you could likely stuff material into. I don't think it would need to be filled to dampen the sound / vibration.

You mean like racing it in 20+ knts of wind and 3-4' waves.

I plan to do the sidebars. I think they should help hold the platform square (vs parallelogram).

I think gluing the sidebars is problematic. The angle of entry into the corner castings changes with tramp tension and weight on the side rail when sailing. They will flex and if the ends are held rigid in the castings?

I think it went well. I did glue the side bars and I didn’t lace the tramp until the glue dried. The result is that the side bars don’t bend as much when the tramp is tightened.
I did not drill out the rivets on the cross beams. I did use a syringe to get some glue in there but I didn’t use and filler for this part. I’ll have to go racing to see if it all works out.

Oh yea and I didn’t pull on the bow and transom to straighten the boat. I thought there was too much risk of just flexing the bow. Instead I went across the platform from casting to casting and pulled the boat square that way.

Never heard of anyone doing it that way before, maybe it's the new cool way. The best way is from pylon to pylon, that way you don't 'square' your boat with one bow forward of the other, which is the point of squaring in the boat in he first place. Is the tramp frame square now?
