Ok here is a question a friend of mine have been debating... when sailing ought one have the transmision placed in reverse or ought the transmision be placed in forward thereby allowing the prop to turn free?

out of water
When sailing you should have the outboard raised to reduce drag. What gear it is in is not an issue (or am I missing something?)

Reverse
I always sail with my Atomic 4 in reverse so that the prop doesn't turn -- if the shaft is spinning without the engine running, there would be no lubrication. Opinions? Am I wrong?

Depends on transmission
Some transmissions aren't lubricated if engine isn't running or if free-turning and the bearings etc. could be ruined. According to Dave Gerr's "Propellor Handbook" if the shaft runs thru a strut and the prop is well clear of the keel, as on a fin keel boat, then there's less drag if the prop is allowed to rotate. If a two-blade prop on a full keel boat, drag is reduced with the prop lined up with the keel

Two different answers
I have an Oday 30 w/5416 universal diesel. I asked this same question last yearturning after taking my first sail with this boat. I shut the engine off with the tranny in forward. After a little while I heard the prop turning. I person answered my question saying reverse is your proper gear and some trannys can be damaged if left in forward. Later I Purchased an owners manual for that engine and it told me I could leave the transmission in neutral when sailing. It has a hurth transmission. Hope that helps.

Jib Roller Furling
What is necessary for roller furling for the daysailer? Size and type? Is it relatively easy to install myself?

on my 17' daysailer
I used a laser style furler, which is basically a spinner managed by an endlessline running back to the cockpit. At the head of the jib I have a swivel, but sometimes it binds, so would recommend a ball bearing swivel instead. Presently I have to relieve the jib halyard tension before furling, otherwise it twists. The line that runs aft through the fairleads on the right of the picture is two 3/16" inch lines that go back to a small turning block on the cuddy roof. The thicker lines are the jib sheets from the jib clew.

harken 435 furler set
the 435 furler set, jib converted to wire luff, and a short length of new forestay, attached together to equal the length of the old forestay, add couple fairleads and a jam cleat at the end. attach to mast and leave alone, raise mast and attach bottom of furler to old forestay attachment point. done. i talked to harken about this for my 14' javelin and they recommended this. would call them and ask first, but will prob also work for you. this is not a reefing system, all or nothing only.
