About the GULFSTAR 41 KTH
Dimensions for ketch rig. See GULFSTAR 41 for more details.
The Gulfstar 41 KTH is a robust, heavy-displacement cruising ketch designed by Lazzara and built by Gulfstar Yachts (USA) in 1973. With a displacement of 22000.0 lb and a comfort ratio of 35.09, this vessel is engineered for stability and seakeeping rather than high-speed performance.
- Best for:
- This boat is ideally suited for experienced coastal cruisers and bluewater adventurers who prioritize comfort, stability, and offshore capability over rapid planing speeds. Its ketch rig and substantial ballast make it a strong candidate for single-handers or couples seeking a safe, steady passage-making platform.
- Bluewater capability:
- With a capsize ratio of 1.72 and a displacement of 22000.0 lb, the Gulfstar 41 KTH demonstrates strong offshore suitability and resistance to capsizing in heavy weather.
- Comparables:
- Comparable vessels include the Cal 40 and the Tartan 40, which share similar heavy-displacement characteristics and cruising-oriented designs from the 1970s. These boats are comparable due to their emphasis on seaworthiness, fin keels, and traditional cruising amenities.
