My '77 Nacra 5.2 has a single trapeze (I guess original). Can I install the double tramp setup on this mast/boat safely? Is anybody double trap'ing on a 5.2?
I double trapped on mine when the wind warranted it the last two summers. It's an absolute blast, but stresses the boat. I wouldn't pass up any opportunities to do it again except that I got another boat that's more suitable for 2-up, so I'll leave the 5.2 for solo from now on.
I installed a double trap on my 1982 without a problem. If your rigging is new and your hulls/chain plates attached to the hulls are in good conditions it should be able to take the load of a couple of light weights (150 lbs or less). Just remember that your boat is 30+ years old so go slow at first until you are sure that nothing is cracking or tearing out of the hulls. Also you don't want to double trap with a pair of 200+ lb people. I don't think any cat is really built for that.
