About the NAUTILUS 36
The Nautilus 36 is a rare, heavy-displacement cruising sloop designed by Henry Adriaanse and built by Niagara Nautic Inc./Aztec Yachts(CAN) with a production run of 40 hulls in 1978. Its substantial build quality and classic lines reflect a focus on durability and comfort, though its limited production numbers make it a unique find in the market.
- Best for:
- This boat is best suited for experienced coastal cruisers and those seeking a comfortable, stable platform for extended weekend trips or short offshore passages, rather than high-performance racing or extreme bluewater expeditions.
- Bluewater capability:
- With a displacement of 14500.0 lb and a low capsize ratio of 1.89, the Nautilus 36 offers excellent stability and seakeeping for coastal and nearshore cruising, though its age and specific structural vulnerabilities require careful assessment for serious offshore use.
- Comparables:
- Comparable boats from this era include the Cal 36 and O'Day 36, which share similar beam dimensions and cruising-oriented layouts, though the Nautilus distinguishes itself with a heavier displacement and distinct Adriaanse hull form.
