About the CORBY 33
Main sail: 35,4m2 Jib: 30m2 Spinnaker: 92m2 At least 15 have been built in Poland. An earlier CORBY 33 was built in the UK.
The Corby 33 is a fractional sloop designed by John Corby and built in 2007, featuring a displacement of 9370.0 lb and a beam of 9.68 ft. With a comfort ratio of 21.46 and a capsize ratio of 1.84, it is engineered for balanced performance and stability.
- Best for:
- This vessel suits coastal cruisers and short-handed sailors who prioritize a responsive fractional sloop rig and modern electronics integration, evidenced by widespread upgrades to B&G and Raymarine systems.
- Bluewater capability:
- With a D/L ratio of 118.43 and a max draft of 7.22 ft, the boat offers moderate offshore capability, though potential structural concerns in the keel and deck core require careful vetting for extended bluewater passages.
- Comparables:
- Comparable to other 33-foot fractional sloop cruisers from the mid-2000s, such as the Beneteau First 33 or O'Day 33, due to similar LOA of 32.81 ft and emphasis on performance cruising.
