Kam,
If you go for a launch in either the solent (sheltered from the wind) or more preferably Poole - you can play and test the boat to your hearts content.
If it is really snotty, we could stay in the harbour, or if just iffy, the headland protects a little of the bay in a W / SSW, so we could even sneak out for a little fishing.
I went out on Friday from Christchurch in a S Force 6! - Sure it was snotty out their, but ok for testing the boat - anf fun in the waves!!!
