Oh nonsense; you get a ton more performance from a rolling mainsail becuase
YOU WILL ALWAYS USE IT; how often do you see people on short evening cruises
with only headsails out b/c their main is too much of a bother to hoist?

Do it.

Just like wind-up headsails, the major loss is in
reliability. Also, there is a loss in safety. Then
there is the loss of money. Finally there is the
loss in dignity.

Don't even THINK about wind-ups.

Keep it simple, keep it seamanlike.

For a cruising boat 35-40 feet, how much performance is lost with an
in-mast
mainsail furling system. What are the specific losses.

Thanks for any info.
