About the LASER SB3
Designed by Tony Castro and built by Dart Sailboats (AUS) starting in 2004, the Laser SB3 is a compact 20.18 ft fractional sloop with a displacement of 1510.0 lb. While the exact hull count is unverified, the model is recognized for its efficient use of space and performance-oriented hull form.
- Best for:
- This boat suits coastal cruisers and weekend racers who prioritize performance and ease of handling over long-range bluewater comfort, given its light displacement and 9.26 comfort ratio.
- Bluewater capability:
- With a capsize ratio of 2.46 and a D/L ratio of 114.82, the SB3 is primarily a coastal cruiser rather than a dedicated bluewater vessel, though its robust construction allows for protected offshore passages.
- Comparables:
- It compares to other 20-foot performance cruisers like the Beneteau First 210 or O'Day 23, sharing similar fractional rig configurations and target audiences seeking a balance of racing pedigree and basic cruising amenities.
