TEAMVMG: Thanks for that. I wonder if there is a decimal more in your cert.

Tiger mast surface is measured at 1,51 sqm.
Since Infusion mast is appr. 3 cm more shouldn't it mean that the Infusion surface is more like 1,75m2?

And yes I know your sailmaker should know this but the problem occurs when you convert a Tiger main for Infusion use.
