At 120 kg (and wings) you would be able to single hand a lot. But, righting is still a safety issue for one person alone and I'd pay serious attention BEFORE you have to do it. Another thing, a lot of the 18s I ran into here in the states had soft (delaminated) hulls. Imo, those are non-repairable and also a safety issue. Thirdly, the boat is heavy for one guy to move around on the beach and that is the primary reason I sold mine and bought a H17. All that aside it's a great boat!
