Nautical Development Offshore 40 Buyer's Guide
The Nautical Development Offshore 40 is a scarce Canadian-built coastal cruiser with only 14 examples launched between 1983 and 1985. For a shopper in the used market, the tiny production run means any available boat deserves a careful look, and the boat’s character as a stable, moderate-weight fiberglass sloop with a single 50-horsepower Ford Lehman diesel sets the baseline for inspection.
Layouts on the Used Market
With only 14 hulls produced, individual used Nautical Development Offshore 40s vary in how prior owners configured the interior, since the source data shows zero cabins and zero berths as unspecified rather than bare. A buyer should view each boat on its own merits and confirm the actual sleeping and head arrangements aboard, noting that the 13.25-foot beam and 35-foot waterline shape the usable volume below.
Equipment and Common Upgrades
The boat carries a single 50-horsepower Ford Lehman diesel and 75 gallons of fuel alongside 150 gallons of water. Used examples may show owner-added navigation or sail-handling gear, but the baseline energy and tankage package is as built, and the masthead sloop rig with 740 square feet of sail area defines the standard canvas plan.
What to Inspect
No known-issue entries for this model appear in the available material. A buyer should therefore apply standard used-sailboat diligence to a solid fiberglass fin-keel spade-rudder hull of which only 14 were built, rather than chasing model-specific fault patterns. Confirm the solid fiberglass hull and deck are free of osmotic blistering and stress cracks at keel and rudder junctions.
Buyer's Takeaway
- Verify the 9,000-pound lead ballast and solid fiberglass hull integrity
- Confirm the 50 HP Ford Lehman diesel service history
- Check the 75-gallon fuel and 150-gallon water tank condition
- Inspect fin keel and spade rudder attachment points
- Validate masthead sloop rigging and 740 sq ft sail plan
