texoma1,

How soft are the tops? Can you push them down more than 1/2"? There's always a solution.
So this is your first boat and it's a catamaran, that's excellent.
Unless you feel the structural integrity of the hulls is going to give, read everything you can find about sailing and especially sailing catamarans, rig the boat and go sailing.

The only caution I can tell you is to pick a day when the winds aren't too strong.

You'll absolutely enjoy it.
