Try not to lash anyting to tramps, if the wind picks up and you need to roll the tramps up, you won't be able too.
If you have gear on the windward tramp you shouldn't have to roll the tramps up. The TI is much more forgiving than the AI regarding the tramps. We have been out in 30+ knots and haven't felt the need to roll up the tramps. Furling the sail to prevent a capsize is much more effective when the wind picks up.
We don't lash to the tramps but we do carry drybags on them, leashed back to the hull and swapped on tacks.
My experience is that on high wind days on an AI the tramps can trap wind underneath them when the windward ama rides up over a wave causing the blow-over. I am sure that furling could help but not necessarily stop the blow-over that happens in an instant.
Having said that I spent this afternoon setting up my custom skirt/half tramps on the new dune model. I have it now so I can roll the tramps and just use the skirt, or both skirt and tramps, or safely rolled away around the from akas. I will report on my success or otherwise when I test the rig out in the near future...Pirate
