A good sailor puts time and money on his boat.
Do not confuse a good sailor taking care and improving his boat for an equipment change making him better.
Better skippers put the best stuff on. Involved sailors will sail more.
Involved sailors will be and get better. Involved sailors will spend more money in their sport.
Do not fall in the 'such and such stuff ' is going to make me better.
I hope I've been clear enough. Money alone can't make you win sailing regattas.
Skill and will will.
FLY THOSE THINGS !
