I've always liked the Group Finot designed Open 5.70 since I first saw one in Le Sables D'Olonne back in the late 1990's. For some reason despite active fleets in Europe and the US it's not really taken off in the UK, well at least around the Solent. Apologies and please let me know if there's a fleet near you, I'd love to come for a sail.
The Group Finot site describes the Open 5.70 as "solid, simple, transportable, unsinkable, hardly capsizable," which is a great description.
Seems to me that the Open 5.70 would make a great boat for beginners and experienced racers who are too old for a skiff, but still want to have a blast sailing and without having to deal with a larger boat's disadvantages.
Maybe in the UK the popular SB3 (now the SB20) took that spot. Perhaps it's just me but I don't seem to see so many of those around these days.
Anyway an Open 5.70 in bright pink might just be the mid life crisis present I need right now.
