Does anyone know for sure if the following specs for the Beneteau 343 rig are as follows (I got these off the documentation on the web) I: 13.24mJ: 3.9mP: 11.93mE: 4.14mLP: 5.07mMy boat is in transit and I'm trying to get a spin made for it. One of the guys who quoted the sail for me had different measurements. This boat has the 'performance pack' on it, but I think in the case of the 343 that doesn't alter the mast height at all so probably not relevant. Alternatively is there a good email address at Beneteau for such technical questions?
