Laser 13 rig settings

Originally posted by Sam.Spoons 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..

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

Its possible to get a new Laser 13 mast .?

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'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?

Mast rake in a dinghy is complex, but the thing it doesn’t really do is change much the position of the CoE of the rig surprisingly. It does change the geometry of the spreaders and how the mast bends.This is why raking the rig will depower the rig by reducing the camber in the main which will thus reduce weather helm. ( the opposite way to what you would think)
Boards are different as the mast foot can be moved a lot and the centre of lateral resistance changes massively as you go from using a centreboard fully down to raked and then onto fully retracted and using the fin 100% .With a board the one thing that is constant throughout all of this is the rig that is unaffected by all these changes.But with both boards and dinghies the aim is the same , in a breeze to balance the rig and foil forces and to minimise drag from both.
