Broker's Comments

I’m not sure comments are needed here – if you are viewing this boat then you probably know all about Sigma 33’s. I’ve had the dubious privilege over the years of seeing them pass me as if I were going astern, then watching their sterns receding into the distance around the windward mark while the rest of the fleet is just crossing the start line.
This particular boat has been well looked after, in the same ownership for many years. She has been used mainly for cruising, and benefits from just having been fully osmosis treated, the work completed in March this year. The engine was rebuilt in 1993, with new injectors, and has been regularly professionally serviced, the most recent being just a few months ago. The Loo is new and unused, and the fresh water pump in the galley is new, complete with charcoal filters. You could eat your dinner off the cabin sole (which you may have to after you’ve jibed round the Needles to take the class lead in the Round the Island Race). A great boat, great pedigree, famous design, a real class act this one!
