Jib vs Genoa
Boat in question is an O'Day 25, Bermuda-rigged sloop. Any general guidelines as to when to use a jib vs. using a (120) genoa? What factors help you make that choice? Wind speed? Point of sail? Others?

I vote average wind speed...

If you don;t have a roller furl use the genny up to 15 kts and the jib above 15kts. Point of wind does not matter over all.

I have an O'Day 302 and had the 155% genny 0n the roller furl out all the way on a close haul until the wind hit 25 kts during a thunder storm at which time we rolled it in to 100%. Almost lost a newby when a wave came over the bow. He learned to hold on real fast. Boat was at 8 kts and rail in the water.

I've got a 170 that only works in about 5 kts or less wind. It stretches back to the helm. My 150 works in about 7 or less and the 120 is good for up to about 15. I switch from a Jib to a storm jib above 18-20 or when my limited expierience sailing makes my spidey sense tingle with impending doom or too much heel.

Most of the time I use a 120.

My dad tells me switch to new sails and/or reef the main when:

Excessive heel
Whooping Crew
Uncomfortable in the cabin
Lack of steering / hard to control
Poor forecast

He also showed me that nothing smooths a boat down like taking 2 knots off of the speed and 10 degrees from the heel!

One problem you can run into, especially on a multihull, is that the apparent wind when running downwind is very low, and then when you come about, the true amount of wind becomes very clear...and you are drastically overcanvassed for the amount of wind. This is how many multihulls, especially racing ones, get into trouble. This isn't generally an issue on monohulls, which don't sail quite as fast.

All depends on the boat. PO told us our boat, a Pearson P30, can handle a 150 genoa nicely up to 20 kts or so, IIRC. As proof: Boat comes with the original main, jib and genoa (all in good condition), and a new main, light 150 and heavy 150. He didn't bother with a new jib, much less a storm jib.

Oh, and two spins, which, someday, we hope to learn to fly ;).
