Winterstale - we did this 5 times in January. Two people, 15hp, standard Sunsail AB RIB. No issues at all. Max wind we had was around 22 knots. We stayed dry.

It takes a little while, but the ride home is with wind & waves so a lot quicker and smoother!

Just watch where you tie your RIB at the beach club...if you're not careful the swell will lump it under the dock and give it bit of a munching.
