Genoa Questions

Just began researching a new genoa and looking for advice. My boat is is a Islander Freeport and used for cruising the Caribbean(eastern and western), Gulf of Mexico and the Americas. I only carry what's mounted on the boat, mainsail and genoa. I've been getting quotes for an offshore sail in 8.3-9.0 oz weight. My question is what size would you recommend, 130 or 150? She's had a 130 for the past 30 years and thousands of miles which seems to work well. Would a 150 give me anything? Her mast is set back a good distance in the boat. It actually looks like theses boats were designed to be cutters so the genoa is pretty big. Thanks.

A 150m is useful in really light air, but turn into a problem as the wind picks up.

Do you have a genoa fairlead car positioned so that you can use a 150?

What was the sail plan design? A larger genoa may upset the balance of the boat.

Will your furler arrangement take a larger genoa?

I never use my 150. It's much more likely to snag on a shroud during a tack than my 135, and I'm frequently single- or short-handed. I have not been able to balance the boat under the 150, though to be fair I have not practiced with it as much as the 135. With the wind around 10 kt, I have no trouble making 4-5 kt with the 135 upwind, and 5-6 on a reach. In the same wind, the 150 would backwind my (old, probably blown-out) main a lot more on a beat.

For light airs (< 5 kt) I have a lightweight (probably nylon) 155% "drifter", and spinnakers for downwind work.

I'm a daysailer/weekender. The 150 doesn't really have a niche to fill in my inventory. It's only on the boat because my wife won't let me keep it under the kitchen table in our apartment.

why a 150?

A 150 is SO BIG and really only useful in very light winds. Racers use them because they have a extra railmeat to counter balance the increased loads. The only real time I have seen one used is on a race boat in light air.

If you are just two of you, I'd forget about the 150 unless you plan to sail in 8 kt winds or less. They are difficult o trim well and if you get a big gust of wind, the boat will be more difficult to sail (helm). You won't see a significant increase in performance in any wind above 8 kts and actually may suffer because the difficult to sail "flat".

A good compromise between performance and handling is a 135 to 125, depending on how you boat is set up. With a fractional, go with a 125, masthead, 135. 130 is basically a good all-around headsail.


If you liked my advice/response, give me some rep points. If you didn't......well what do you expect, it was free.

Given the generally reliable trades in most areas you're frequenting, the large J measurement you describe, and the fact that you're cruising I can't imagine why you'd consider a 150... I suspect you'd rarely actually make full use of it, and that's quite a few more feet of heavily loaded sheet to grind in on each tack.. (but you may not tack often, I suppose......)

Cutters are designed to carry Yankees (about 110%). We use a 135% as are primary head sail that reefs to 110%. Cutters are nice as when reefed correctly the center of effort can be kept over the keel.

I'd recommend going with a 120-130% genny and then getting a screacher or code 0 for light air situations later on.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
