The Tool A Class Catamaran Sailing 23 Oct 2016

Matt, you really should read up about mast rotation. It looks like you could do with a bit more mast rotation. You can get a lot more power.

Going to windward, it should be around 15 to 25 degrees (depends on the rig and wind speed) more than the boom. On a beam to broad reach, it could go as high as 60 degrees or even 90 degrees more than the boom.

If you don't believe me, stick on some tell-tales about a foot back from the luff/mast. You only need 3 or 4 on each side. You want the leeward side tell-tales to be streaming freely. It doesn't matter as much about the windward side, close-to-the-mast, tell-tales. If they are lifting a bit, that's OK. By about a third of the way back, the windward ones should also be free flowing. If you can get a clean flow around the mast and onto the leeward side, you'll get more lift and less drag.

The A Class is an extremely easy boat to sail. Rolls Royce ride. It's much easier than any of the mono-hulls I've sailed (11+, National 12, Firefly, Albacore, Osprey, Finn, OK, 505, Enterprise, Laser, etc.). It's also much easier to sail than the Hobies and Pringles that have been inflicted on me. However, it's not easy to get the best out of it. The rig looks simple, but it's very sophisticated and can be tweaked to handle all sorts of conditions with a few changes of mast rotation, outhaul position, luff tension, traveler position and mainsheet tension.

I think that you could go faster and have more enjoyment.

cool video Mathew :) . Have u shared it on sosailize.net ?

Contour +2 HD camera it records GPS telemetry as well.

What camera are you using?

Looks cold bbrrrrr.

The Tool still looks and goes well Matt.
