Fine Line is a custom 40’ Billy Knowles cold-molded express sportfish. Considered by many to be one of the finest mid-sized express boats ever made, she was the inspiration for the 44 Garlington.  She has just completed an extensive 3 year open-checkbook refit by a team of the finest craftsman including new engines, gears, genset, electronic controls, hydraulics, tower, enclosure, electronics, refrigeration, teak, paint and bottom fairing.  Benefitting from meticulous maintenance and a complete service history, she shows as new with low hours. Fine Line delivers that elusive combination of economy, speed, acceleration, and maneuverability.  She is equally at home fishing the Bahamas, Sailfish Alley, or prowling the Canyons.  Her soft, dry ride and seaworthy manners will impress the most discerning buyer.  If you desire the one of the very best examples of a classic South Florida custom sportfishing yacht, look no further.

100 Hour Service on Engines and Generator just completed by Yanmar Dealer 2/18/2015

Brokers Comments
This custom cold-molded masterpiece of South Florida boatbuilding art, shows as new and is entirely turn –key and ready to fish.  She has been fully “dialed in” by her experienced broker-owner getting 1 nmpg at a cruise of 26 knots.  Guaranteed to be one of the best riding boats of her size, period.  The most common comment Fine Line receives is “She is the nicest looking boat I’ve ever seen”.  Come see her for yourself!
