I've been sailing my F18 (2004 Nacra) for a few months now, including a 70 nm raid. The learning curve is steep indeed on those boats, but I still have a few unresolved issues mostly dealing with how to manage the boat under spinnaker (F18 people actually call it a jennaker here in Italy).
Anyway, my first fundamental question is: how to react to a puff, when the windward hull starts to fly a bit too much? I've been experimenting a bit lately and find easingthe main traveler (let alone the sheet) almost uneffective. The only viable way to flatten the boat is to bear away, but the change in direction is very substantial and the boat looses speed a lot. What am I doing wrong?
