Very light here most of the time.
SWMBO likes light air sailing, she does not like fuss and muss sailing (hence she does not go with us when we race.)

So one of the important design issues was to have a vessel that performed well in our light air because I like having her aboard for day-sailing.

Sure looks like Bob nailed the light air issue.

There's a frightening amount of scope for more sail area between the masthead and anchor roller when you're cracked off a bit in the light stuff. You'll properly fuck off then. I would be tempted to use a sail maker who's done that sort of stuff before for that.

The sailmaking brothers Schattauer and I are discussing that very issue........

Are you trying to build a sail that will go upwind, or more of a fetching/reaching sail?

She looks in the pics like she was trundling along OK upwind with what you've got.

Bloke:

As you say, we don't need any help upwind. I think Kim's next sail will be an asym for off the wind.

Kim got his PHRF rating yesterday. 21 NFS, -3 WFS. I think I posted some wrong numbers the other day. Although the -3 may change depending on the exact chute Kim gets.

I was wondering if you'd be looking at a tight luffed, flat, probably high cut sail in dacron/mylar/kevlar/spectra/whatever, that you can use when it's too tight for a traditional nylon aysm.

I don't think it would be good for your rating, but would be good for cruising progress on the light days.

I have no idea what Kim plans. We need a good reaching sail. The boat pulls the AWA well forward very easily.

Given the ease that she builds and carries speed, and how far forward the apparent wind angle was even under white sails when we cracked off, Kim will have an interesting discussion in deciding what shape the asymm should have and for what wind angle.

I have no set plans, just exploring options.

I do not care what it does to the rating, I only want the Frankie to sail very well, after all she was conceived "for the pure pleasure of sailing."

We will race her because racing seems to sharpen up the sailing skills of everyone aboard. I will leave the handicap math to those who care about such things.

Reaching, of course. Something like a code0 or such. On a free hoisted furler.
Yup. I think she'll meet or exceed most 'normal' multihull speeds... at least for all but the raciest multihulls. This will be especially true in lighter airs where FL doesn't have the stickiness of a multihull. An extra knot even, of boat speed in light air really starts pulling the apparent wind fwd significantly.

Or maybe two masthead asymmetrical chutes, one fuller for running down and something like a code0 for close reaching?

All in good time gentlemen, first we have to sort her out and get to know her sailing characteristics. (We already know her structure and build details well.)

I spent some time in her cockpit yesterday whipping all of the sheet and other line ends. Also put the fractional heavy air 1.5 ounce asymmetrical kite aboard. It takes up all of one of the forward "empty" compartments, but it is soft enough I suspect someone could sleep on it. Guess we don't need those pipe berths after all.

I'd lean towards the flatter chute. Probably best to try out the non masthead chute out that Kim has now and see how that works. Then make a decision. I think a versatile sail would be nice.
