Should I raise my genoa with an extension?

Currently I attach the tack directly to the hardware on the deck. I have about 18" available at the top of the forestay to raise the sail higher. All I need is a short piece of sta-set to make the extension between the tack of the sail and the connecting point at the bow. Would I get any appreciable improvement by doing this?

You would have better vision, less chafe on the bottom, Doubt that it would improve sailing much enough to notice.

A lower sail will generally give you better performance if at deck level. The wind is better contained in the sail.

If you are using a furler, you better ensure that the halyard is the correct length when the sail is raised or you will get halyard wrap.

No furler...hanked on. I could use some improved visibility forward. My jib's foot is cut upward enough that I can see under it. The genoa's foot is cut much flatter and makes it a b@#$h to see what I'm about to run into.

Re: Should I raise my genoa with an extension?

If you raise the sail you need to move the genoa car aft, otherwise you tension the leach. Looks like you have a fixed eye, so you should not raise the sail. On 420s we had a short chain to adjust leach tension. A few inches of chain made a difference on a much smaller boat, so I'm sure a foot would really adversely affect your performance.

Re: Should I raise my genoa with an extension?

A headsail close to the deck will benefit from the "end-plate effect" when sailing relatively close to the wind, and it will keep the moment arm of the sail as low as possible (so the boat won't heel quite as much). Off the wind, neither of these effects will matter much.

A headsail with a short pendant on the tack will give the helmsman more visibility at the cost of a bit of efficiency (for the reasons above). Unless you're racing, the gain in visibility is usually worth the very slight loss in drive.

Your jib isn't a deck sweeper so it isn't getting much, if any end plate effect from the deck. Raise it and get the visibility. I did this on my old 20' and it had no effect on performance. If you have a stretchy luff you can use a small dinghy size tackle as a "tack pennant" to enable you to stretch the luff when the sail is hoisted to the masthead block.

I, myself, personally intend to continue being outspoken and opinionated, intolerant of all fanatics, fools and ignoramuses, deeply suspicious of all those who have "found the answer" and on my bad days, downright rude.

I know this is a trivial point, but I'll suggest that it's a "tack pennant".

I looked around the Web a bit, and apparently both terms (pennant or pendant) are used for such a thing. However, a thin tapering flag is only referred to as a pennant (from the Middle English word, penon, which was in turn derived from the Old French word pene, for feather). The term pendant seems to be derived from Old French for something attached to a short line or chain (as in a piece of jewelry). So the latter is probably more correct.

Pendent is an adjective referring to the condition of hanging (e.g., a lamp could be pendent, from a pendant)

(There will be a quiz next week. Bring a short-form Bluebook and a pen.)
