 Topic: Radial rake measurementPosted: 18 Jan 16 at 2:18pm |
As did I when I bought a new Laser (180,000 vintage). A friend of mine however didn't as the hull had visible stress cracks all over it so he refused it. After several hours or discussion and him demanding a refund they eventually replaced the hull with a new one (and had to change the numbers etc.. that they had packed for him).

All the rake guidelines I know of are based on the standard mast, you'd be better borrowing a full rig and measuring top to transom on that.
For the standard rig I've always been told they're *supposed* to be about 382.27/383.54cm or 150.5/151in from the top of the mast. A bit of forward rake (Up to 386cm/152in) is better because it's quick off the wind and gives you better leech tension upwind. If the measurement is less than 376 cm/148in you've got an issue with the bottom of your mast step and the boat's a dud. |

Thanks 47.
148"-152" is a substantial variation, as you said I'll have to borrow a std section.
Exactly where on the transom?
Thanks again.

From the top/back of the mast to the middle of the round of the transom (just above the rudder fittings).
There's pictures and instructions to measure everything in the older versions of the Laser Campaign Manual, I'm not sure about the newer version because no-one really measures anymore: the XD makes it less of an issue and they seem to have clamped down on the tolerances since the early 2000s. |

Take it from someone who is currently active in the class and has had 3 brand new ones - there are still big variations.
For most sailors, it's not going to matter what the measurement is, you just want to make sure you don't have an outlier. If you're not as quick as other people it's much more likely to be your technique than anything else!
