About the LM MERMAID 315

Sailpages Buyer's Take

Designed by Bent Juul Andersen and built by LM Glasfiber A/S (DEN) from 1983–1989, the LM Mermaid 315 is a compact, heavy-displacement cruiser with only 65 hulls produced. Its substantial displacement of 10582.0 lb and high D/L ratio of 261.18 indicate a solid, motion-comfortable vessel built for stability rather than speed.

Best for:
This boat suits coastal cruisers and weekend sailors who prioritize a stable, comfortable ride and low maintenance over high-performance racing. Its manageable size and robust construction make it ideal for couples or small families seeking a reliable, no-nonsense sailing experience.
Bluewater capability:
With a low capsize ratio of 1.83 and a high comfort ratio of 27.57, the Mermaid 315 is well-suited for protected coastal passages and short offshore trips, though its limited production run and age warrant careful inspection for long-range bluewater use.
Comparables:
Comparable boats include the Nauticat 31 and the Beneteau First 31, which share similar beam widths and masthead sloop rigs from the same era. These vessels offer similar coastal cruising capabilities, though the Mermaid’s higher displacement distinguishes it as a heavier, more stable alternative.
