The 6.0 with the boards up should be similiar and I don't have any problem.

<br>Part of the problem is the boomless main. Try setting your mainsail traveler to the upwind position, travel out about halfway and sheet in hard. If the boat pops up quickly travel out until the windward hull comes up slowly.

<br>Also you might try practicing in calm water. Anything over 2 foot chop and you will have a hard time telling if the problem is the waves or the boat <br><br>
