Welcome to the OP. If you are very new to boating I suspect a Helmsman course might help build your confidence. We didn't do one when we bought because we had both a bit of experience before (me a little, husband a lot). Otherwise I definitely would have. Keep in mind that all boats handle differently and can be affected by conditions in different ways - water depth, wind etc. I'm going to be very honest (and open myself up to a fair bit of banter) and say that it is only this year (3rd season, 1000 hours in) that I have felt properly confident handling my boat. Previously I've had to concentrate really hard - a bit like when you are learning to drive a car. Now it feels much more second nature. Don't worry about having to be an expert overnight. People are generally very helpful and forgiving. Go for it - and hopefully you will love it as much as we do.
