In Catalina all the moorings have 'sand lines' to keep everyone in one place. Friends of ours had a tri and the 'sand line' was always a big problem as you need to get it around the amas and they're too short to do it without putting a multihull sideways.

Our big boat with a lot of windage was always white knuckes when picking up a mooring there but your tri is something I'd like to video as you try it for the first time. There's a product called the 'Catalina Coil' that might be a good product for your boat.
