Hook, strap or line to attach clew to boom?

Trying to pick up some advice from the pros.

I really like the ability to unhook the clew of the sail as I get close to a dock so that I can drift in and make fast. For me, the (Harken) clew hook has worked well, but it may not be super secure in big wind. I find a clew strap difficult to undo fast as I try to dock. Moreover, the outhaul will still be attached to the clew and the sail won't be 'free' to move around.

Opinions and/or advice appreciated
