As Rolf says, if the read tape is so great in your location, please join the International association so you can be part of the class and have a vote.
Ok, so i tried to join the international association and guess what? Singaporean isn't one of the nationalities available nor is our country's sail number designation (Sin) available as an option, and since those were mandatory fields, I was unable to move forward with my application.
Anyway, as far as F16 weight goes, I don't think the sailors here in Singapore take racing seriously enough to care if the viper is 107kgs or 125kgs (also maybe that's why they haven't been clamoring to join any f16 association of any sort unless the association starts organizing picnics and such).
It's actually kinda funny how we watch from the outside as everyone debates the weight issue while we just go sail. I think our general fleet attitude is that if the boat looks good and sails well, get me one of those. it's not like any of us are headed for the olympics anytime soon or hitting up the european racing circuit. guess that's why the viper fleet is growing so fast here. it's a boat that sails well and looks good. and since there isn't an option to buy a 107 kg version of the boat (and we probably wouldn't if we had to pay a lot more for a 107kg version, i means, it's not like out racing is neck to neck anyway), heck, why stress about the weight, just come out and play. Just my take on it and some insight to the local fleet mentality.
