How would you try to avoid this tidal marina collision?

Roscoff Marina is one of the few all-tide ports in North Brittany.

However, whilst it doesn’t have any depth restrictions, it does have a strong current which sets south through the marina on the flood, and north on the ebb. Ben has chartered a Beneteau First 40.7 for a sailing holiday along the Granite Rose Coast, just east of Roscoff, but has sought shelter from a gale in Roscoff. Ben is a qualified Yachtmaster Offshore. He has three friends on board, all of whom are Day Skipper level. They've set up lines port-side-to and entered the marina on the flood in a northerly F4, with the intention of turning back into the wind and tide to an empty berth on ‘A’ pontoon. However, Ben was distracted as they made the turn around ‘A’ hammerhead and left it too late. It now looks as though they'll be set onto the sterns of the yachts downstream. He has moments to choose a course of action and considers two options: power forwards and try to turn the boat into the tide, or reverse out as fast as possible. What should he do?
