Most of the 18HT's using snuffers have rigged a continous spin halyard/belly (retrieval) line. The line passes through a block on the rear beam and has just enough slack for the crew to get long pulls during the hoist. The system works very well, I know a lot of the I20 guys have a similar setup. As for rigging the tack line as well, Brian Lambert and Jamie Livingston used that setup at Tradewinds and it appeared to work very well, even in the breeze.
