About the AMPHIBIAN 30
Winner in class at the MORC Internationals a number of times. Only 2 built: ('Cowboy' & 'Rabble'.) Thanks to 'SPB' for additional information.
The Amphibian 30 is an extremely rare vessel, with only 2 hulls built in 1981, designed by Nelson/Marek. Its unique identity is defined by its amphibious nature, combining a 29.81 ft LOA with a 10.2 ft beam and 6500.0 lb displacement.
- Best for:
- This boat suits adventurous owners seeking a unique hybrid experience, specifically those interested in both sailing and powerboat capabilities, rather than traditional single-purpose cruisers.
- Bluewater capability:
- With a capsize ratio of 2.19 and a displacement of 6500.0 lb, the hull form suggests moderate stability, but its amphibious nature and limited production history make offshore suitability difficult to assess without specific owner reports on sea-keeping.
- Comparables:
- Due to its unique amphibious design and limited production, it has no direct conventional sailing comparables, though its dimensions are similar to late-1970s/early-1980s 30-footers like the Cal 30 or O'Day 30, albeit with a much wider beam.
