I like the idea of a triangular "recovery tarp". (You can't really call it a sail, can you?) We plan to get one next month. It will clip onto stanchion bases so the outboard pennant end will be near our primary winches and be within range of our running backstay tackles as well. The Lifesling is really designed to only get the victim back to the boat. Lifting a victim with a Lifesling loop looks like an easy way to have him slip out, and then have to retrieve him again. Using the Lifesling to get him into the tarp keeps him secure in the tarp and then the lifting tarp makes him even more secure. Our lifelines are also tied off with line at the ends so a swipe of a knife can loosen them and allow passage to a victim if needed.
Our club is planning a MOB drill during a race in June. Changes to the sailing instructions that day will provide each boat a watermelon to carry aboard. Upon a radio signal from the Race Committee boat, all boats will jettison their watermelons and then retrieve them before continuing in the race. Boats failing to retrieve their watermelon will have 2 hours added to their corrected time. We think that finding a small, darkish, round, bobbing object, and getting it back aboard undamaged (no lifejackets or harnesses on the melon, either) is much more realistic than using a boathook to snag the strap on a big white cushion. Discussion this year has included possibly greasing the melons, but the the 18 knot breeze and 2-3 foot chop we had last year made it difficult enough without it having to be messy too. Now to get 20 watermelons...
