Ok, was out doing some more spinny practice yesterday when the sheet block pulled out the tramp webbing strap. Here is the setup prior to the webbing failure:

Should I just get new webbing and re-attach it or is there a better solution out there?

Hi,

I have seen two different solutions to the problem:

(1) Attach the block directly to the trampoline hook.

If you do not trust the small hook to carry the load,
you may also

(2) drill a hole into the hull right inbetween two of those small hooks and fix a larger hook using some epoxy glue.

Regards,

Hi Mike

I have the same aussie tramp that you have. I just had the loops on the tramp replaced with a heavier grade of loop material because they were wearing out. (The spin loops were taking the worst of it though). The new loops are far superior with respect to tensioning the tramp.

Marstrom used two sizes of hooks in the boats. The older boats had smaller hooks and they can break. (been there... done that always keep the tramp tensioned so that the loads don't push down on one particular hook when you stand) By attaching to the loops you distribute the spin load to several hooks.

My solution was to put grommets in with a backing sheet running just inside the tramp edge. My old Ulman chute looks good quite a bit farther aft then my (new to me) Gran segal chute. I don't know about the new Ulman's (which are supposed to be great)

I don't think the small move inboard is that detrimental. Enough flexibility fore aft is very important.

Hopefully you can get the tramp off the front beam easily... Its a real pain for the sail maker to work on the tramp with the front beam attached.

Good luck
Mark
