I once said that the Vision was the worst dinghy I ever sailed. That might have been an exaggeration in the heat of the moment (but even on reflection it's hard to think of a worse one I've sailed - I've not actually sailed any of the Topper rotomoulds).

But the Vision has a horribly heavy helm, and heavy mainsheet load, and was simply totally unsatisfying.

The L2000 is a much nicer boat, once you've accepted that it has far too much built-in buoyancy and thus inverts completely as soon as you capsize unless you're very quickly onto the centreboard. Just reckon that you'll need to sail around with a big float at the masthead.
