While it won't be as exaggerated as a windsurfer, it does make a difference, I prefer a bit of weather helm.

I'm a windsurfer and our primary means of steering is mast rake
 but the range of movement is rather more than mast rake in a dinghy. But rake must affect the helm balance?

I don’t think that rake and or mast foot position affect the balance of the helm directly, but they do affect mast bend which has a big affect on helm balance. Normally setting it up so there is some 1 to 2” of prebend is a good start. If you get over bend creases at that straighten it up a tad.

Thanks gents, It's mostly how much rake will give the best balance. I'll go and sail it with him and experiment a bit.
I can't see a problem with getting a new mast unless it's an obsolete section, it's un-tapered I think and it'll almost certainly be a common stock section. But I reckon it's an easy fix if not.

I know nothing about Laser 13s. But as a rough guide in the absence of anything else for starters..
Big main, small jib ...mast step..mid setting ...put the mast up ...hoist jib ....pull rig tension to abt 350 lbs ...mast rake...tiny jib big main so it probs need to be a little bit aft of upright ....spreaders....so that shrouds are maybe prodded slightly aft of in line, but make sure squared across the boat And make sure the mast is properly upright and not bending off to one side. Hope thats helpful! |

Forestay failure parked up plus gale force winds. The mast foot was bolted to the step and it's torn the rivet holes out of the tube. Probably fixable if we cut an inch off but if the insurance will pay...
That said it's just a standard section and they do break, though I reckon the hull will be around for the cockroaches to sail after the apocalypse

Just interested. Under what conditions did the mast break? I always thought the L13 and its kit was pretty robust. |

A mate has a L13 and, as he has just had the misfortune to break his mast, (replacement will be claimed for) I though it would be worth getting some settings so that when we rig the new mast it'll be in the right place. Can anybody help with rake and tension numbers please? It's not for serious racing but we just want the boat to be as manageable as possible over a range of wind strengths..
