Paul,

indeed best way to reduce forward pull is to length the bungee attached to the trap wire.

In my experience it is best to have the bungee go underneath the tramp then run to the other side, run over a small block that is attached to the underside of the tramp then back to the first side, run over a small block under the tramp there and only then go to the trap line on lee.

This increases the bungee length from about 2.5 mtr to roughly 4.25 mtr. The pull on the line is now much more constant, meaning you have more pull on the trap line when it is not in use while having less pull when the trap line is used.

The next step is using 4 mm bungee line instead of 5 mm. This seemed to have solved the remainder of the issues.

Attaching the small blocks to the underside of the tramp can be done by stitching small loops to it (sailmaker) and then using a tie wrap to attach the block to the loop.
