competed in the Half Ton Cup in Poole in 1978 but did not perform well against the one-off designs such as ‘Waverider’ which has competed in the last two Half Ton Cups. ‘Feanor’ has not been seen sailing in Irish waters since Jim Poole died in an accident after an ISORA race in 198???. Where is ‘Feanor’ now.
