SB20 is a 20 ′ 2 ″ / 6.2 m monohull sailboat designed by Tony Castro and built by Dart Sailboats starting in 2004.
Rig and Sails
Auxilary power, accomodations, calculations.
The theoretical maximum speed that a displacement hull can move efficiently through the water is determined by it's waterline length and displacement. It may be unable to reach this speed if the boat is underpowered or heavily loaded, though it may exceed this speed given enough power. Read more.
Classic hull speed formula:
Hull Speed = 1.34 x √LWL
Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio .311 Hull Speed = Max Speed/Length ratio x √LWL
Sail Area / Displacement Ratio
A measure of the power of the sails relative to the weight of the boat. The higher the number, the higher the performance, but the harder the boat will be to handle. This ratio is a "non-dimensional" value that facilitates comparisons between boats of different types and sizes. Read more.
SA/D = SA ÷ (D ÷ 64) 2/3
- SA : Sail area in square feet, derived by adding the mainsail area to 100% of the foretriangle area (the lateral area above the deck between the mast and the forestay).
- D : Displacement in pounds.
Ballast / Displacement Ratio
A measure of the stability of a boat's hull that suggests how well a monohull will stand up to its sails. The ballast displacement ratio indicates how much of the weight of a boat is placed for maximum stability against capsizing and is an indicator of stiffness and resistance to capsize.
Ballast / Displacement * 100
Displacement / Length Ratio
A measure of the weight of the boat relative to it's length at the waterline. The higher a boat’s D/L ratio, the more easily it will carry a load and the more comfortable its motion will be. The lower a boat's ratio is, the less power it takes to drive the boat to its nominal hull speed or beyond. Read more.
D/L = (D ÷ 2240) ÷ (0.01 x LWL)³
- D: Displacement of the boat in pounds.
- LWL: Waterline length in feet
Comfort Ratio
This ratio assess how quickly and abruptly a boat’s hull reacts to waves in a significant seaway, these being the elements of a boat’s motion most likely to cause seasickness. Read more.
Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam 1.33 )
- D: Displacement of the boat in pounds
- LOA: Length overall in feet
- Beam: Width of boat at the widest point in feet
Capsize Screening Formula
This formula attempts to indicate whether a given boat might be too wide and light to readily right itself after being overturned in extreme conditions. Read more.
CSV = Beam ÷ ³√(D / 64)
Originally called the LASER SB3, it was built in Malaysia and sold by Laser Performance under licence from the designer until 2012. Class rules specify a crew weight limit and prohibit hiking. It is thought that more than 700 boats have been built.

Fast, fun and affordable
The SB20 is a one-design class of sailboat commonly used for racing. Marketed and distributed by Sportsboat World, the boat was designed by Tony Castro and launched in 2002. The SB20 was originally called the Laser SB3, and was marketed and distributed by Laser Performance under licence from the designer. This licence ended in 2012.
The boat is an open keelboat and is designed for racing with a crew of 3 (or 4) whose maximum weight must not exceed 270 kg. With a high aspect ratio keel with a very high ballast ratio the yacht is very stable, but also quite fast due to the substantial sail area. This makes for highly tactical upwind sailing and fast and exciting downwind sailing.
The SB20 is unique in that it does not allow hiking, using a small stainless steel bar to prevent hiking by the crew, this allows competitive crews of all shapes, sizes and ages. The boat is a strict one-design keelboat that makes for close racing.
There are over 800 boats worldwide, sailed in over 20 countries. The majority of boats are located in the United Kingdom, Ireland, Portugal, France, Australia, Singapore, Russia, the Netherlands, Germany, Abu Dhabi/Dubai and Italy, and the Class has attracted considerable support.
