About the FASTBACK 43
Twin keels with single daggerboard in the starboard hull. Specs above are from third party sources and not verified,
The Fastback 43 is a distinctive catamaran designed by John Gross and built by Fastback Catamarans, with production records indicating a build year of 1987. As a fractional sloop with a 44.0 ft LOA and 21.0 ft beam, it represents a specific era of performance-oriented multihull design.
- Best for:
- This vessel suits coastal cruisers and performance-oriented sailors who prioritize speed and spacious living areas over heavy offshore provisioning, given its relatively light displacement of 15432.0 lb and narrow comfort ratio of 9.61.
- Bluewater capability:
- With a low capsize ratio of 3.38 and a displacement of 15432.0 lb, the boat is capable of offshore passages but requires careful weight management and experienced handling due to its light displacement and wide beam.
- Comparables:
- Comparable boats include other 1980s performance catamarans such as the Lagoon 400 or Fountaine-Pajot models, which share similar fractional sloop rigs and target the same market of active weekend cruisers.
