About the TRIDENT 80

Sailpages Buyer's Take

Designed by D. Tortarolo and built by Bateaux Neptune (FRA) between 1975–1981, the Trident 80 is a compact fractional sloop with 600 hulls built. Its 5180.0 lb displacement and 21.33 SA/D ratio suggest a design prioritizing responsive handling and performance in light to moderate winds.

Best for:
This boat suits coastal cruisers and weekend racers who value a manageable 26.25 ft LOA and fractional rig for easier single-handed or short-handed sailing. Its moderate comfort ratio of 16.26 indicates it is best suited for protected waters rather than heavy-weather offshore passages.
Bluewater capability:
With a capsize ratio of 2.22 and a relatively light displacement of 5180.0 lb, the Trident 80 is not ideally suited for extended bluewater cruising, as its fin keel and moderate ballast ratio prioritize coastal agility over heavy-weather stability.
Comparables:
Comparable boats include the O'Day 27 and Pearson 26, which share similar fractional sloop rigs and displacement ranges from the mid-1970s. These models offer similar coastal cruising capabilities and maintenance profiles, making them direct competitors in the used market.
