You should find someone on here who can help. I used to offer 'down island' trips regularly on TTOL in the past and never had any problems getting crew. You are coming the right way so that helps! If you don't get an offer in a few days I can provide contact details for a few crew members including amateur skippers who've done the trip previously.

I'd like to help but I'm stuck in the UK for the foreseeable future.

P.S. What's the boat?
