Swan 411
Description
The Swan 411 is a classic 40'10" (12.44 m) fiberglass monohull sailboat designed by Sparkman & Stephens (design #2150-C1) as an enhanced development of the Swan 41, focusing on improved windward performance through a deeper draft while retaining the original's balanced seaworthiness and racing heritage for offshore cruising and family adventures. Built by Nautor Swan in Pietarsaari, Finland, from 1977 to 1979 with 42 hulls produced, it features a fin keel (initially 6'10" draft, increased to 8'0" after hull #20 for better upwind pointing), skeg-hung rudder for protected steering, masthead sloop or cutter rig, and elegant lines with a raked stem, moderate beam, and counter stern—delivering a hull speed of 7.4 knots and a moderate displacement/length ratio (around 280) that ensures stiffness and stability in heavy weather, with a sail area/displacement ratio of 16.5 for responsive handling that's maneuverable for its size and excels downwind with a spinnaker.
