About the KER 33
BAS 1.56 m
The Ker 33 is a modern performance cruiser designed by Jason Ker and built by McConaghy Boats, with production records indicating a build year of 2014. While the exact total hull count is unspecified in the available data, the model is characterized by its fractional sloop rig and fin keel configuration.
- Best for:
- This boat suits performance-oriented coastal cruisers and short-handed sailors who prioritize speed and handling, as evidenced by the high prevalence of North sails and Garmin electronics upgrades among owners.
- Bluewater capability:
- With a displacement of 8267.0 lb and a capsize ratio of 2.37, the Ker 33 is designed for coastal cruising and protected waters rather than heavy offshore bluewater passage-making.
- Comparables:
- Comparable boats include other McConaghy-built performance cruisers from the same era, such as the Ker 36 or Ker 39, which share similar hull forms and racing pedigree.
