Firebird

This looks like an 8 meter Firebird catamaran, although the wrap around windows are unusual, very dramatic and striking, but unusual

The Firebirds are a west country class catamaran historically sailing from from Flushing Sailing Club in Falmouth harbour.

The boats are described as a revolutionary design, with carbon and GRP construction making them very light and (before the foiling era!) one of the fastest sailing craft in the Cornish waters and I'm sure an absolute blast to sail

 Seen in a Hamble marina, so maybe an Around the Island entry, certainly a Firebird did the race in a record breaking 4 hours and 27 minutes back in 2012. This fold up transom is an interesting detail, presumably to fit in with trailing regulations
