The max weight is 420g and the min keel weight is 380g from what iv read on the rules, dont make the bulb to pointy or it will course more drag
I think later on if i ever did get another bulb to put on the other keel iv got, i will make it bang on 380g for light winds. In the boating world in lighter airs you move the weight faward to help with the boats drag through the water ( gets the stern up abit ) which helps with the drag
polishin the hull and deck, keel, bulb, rudder helps alot, if you polish the deck it will help the water run off which helps keep the weight down in raining or ruf weather ( seems silly but even alittle bit of water on the deck adds a good bit of weight )
Then do you wanna keep the stock mast, or put on a pro mast
With all the mods all you are left with in the end is the hull and deck from the kit lol hmm
