Specifications
The official organisation for the A-Class catamaran is the IACA (International A division Catamarans Association).
The A-Class rules were expanded over time to prevent the cost of these boats from rising too high and to ensure fairness in racing.
Currently the main A-Class class rules are:
- Min overall boat weight : 75 kg
- Max overall boat length : 5.49 m (= still the old IYRU rule)
- Max overall boat width : 2.30 m (= still the old IYRU rule)
- Max sail area incl. mast : 13.94 m2 (= still the old IYRU rule)
In handicap racing, the A-Class catamaran uses a Portsmouth Yardstick of 681 in the UK or a D-PN of 64.5 in the USA.
