About the SB20
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.
Direct variant of the SB20
Near-identical models — same hull, builder and designer, re-badged or lightly changed. Specs and owner-reported issues are typically shared across the group, so a sister model's page may carry detail this one doesn't.
