Quite like the racing boats with foils ,not the foils Butthe mast position and three headsails would that work with a ordinary keel set up?

The trouble with code sails on more prosaic craft is that their useful wind angle range is too limited to justify the cost. We have one, and our asymmetric kite is the sail of choice if the true wind angle is greater than about 120 degrees, and we are fast by anyone’s standards. The Code 0 is fantastic between say 60 and 120 degrees, particularly if the wind is light, it gives so much drive and generates high apparent wind. That isn’t going to work if you’re limited to 7 knots. Not to say you wouldn’t have fun trying.

It was the engine that did for sailing boats with clouds of sails I order to sail in light winds .The code zero is sort of byway of a return to setting sail to sail in light winds .The early Hillyards set much more sail then by the advent of the 9 and 12 toners they had been reduced to safe motor sailers(asan example)

We certainly see ours like that. 800 sq ft of white sail enables us to keep moving when everyone around us has resorted to the iron genoa.

That puts us at half the weight and twice the area of a certain revered 32ft yacht. Which explains the disparity in light airs performance.

Yes and no...
In very light winds, less than say 5 knots, it doesn't really matter how much sail you have if you are dragging around a big wide hull. You'll never be as fast as a narrow boat with significantly lower wetted surface area. As an example, even though the J109s are nearly 1500kg heavier than us, and have worse SA/D ratios, because we have a big bottom then in the very lightest conditions we really struggle against them. Once we have enough wind to heel the boat properly onto her chine and reduce the wetted surface area, we can keep up. Rule of thumb for us is that above 8 knots we expect to be competitive with them, below that we need to work very hard. But above 15 knots we feel we have the advantage.
Code sails (and to be fair the cruising versions are much better sails than the ones designed to measure as spinnakers) can help to solve one part of the problem, but hull design is really more important when you're talking about light wind speed.

What kind of boat do you have?
