rotating wing on a cruiser

[rskaug]

I'm looking for a cruising catamaran to buy and because I'm specifically not looking for luxury accomodations by default the field is narrowed to mainly performance cruisers. Two on my short list have rotating wing masts. One is aluminum the other is carbon/epoxy. I've read mixed reviews from experts. Does anybody in this vast deep knowlege pool of Sailnet have first hand experience?
1) Is the managing the trim line going to seem like more trouble than it's worth?
2) Maintanance burden?
3) Durability compared to conventional mast?
4) Is the presumed increased sail efficiency more noticeable in light air or stronger winds.
5) I've heard they sail at anchor somewhat as monohulls will.
6) Can one heave to with no canvas up?
7-10) Questions I don't know to ask.

Thanks, Dick

One problem with rotating masts is the masthead tricolor. Since the mast rotates, you can't use a normal tricolor... the most common setup to deal with this is two different tricolor lights, one set up for the mast on a port tack, and one set for the mast on a starboard tack.

Rotating masts are more maintenance, since they have moving parts.

I think a fixed mast would be easier to repair, lower maintenance and more durable.

Generally, the rotating masts will be more efficient than a fixed mast.

If you use a bridle or anchor via one of the hulls, you can get minimize the sailing at anchor. Generally, it is less of a problem than it is with monohulls.

Heaving to depends on the wind, wave and boat specifically, so I can't really say.
