There have been production 14' cats sailing in Australia since 1980 with mast heights above 24'. the Alpha Omega 4.4 has a mast hieght of 25' (excluding all fittings) Berny 's cat is over 25', the calypso 14A has a mast height of either 26 or 27 ft nacra Australia have a "14'" with the height way up there, and all of these cats perform extremely well with less inherent "stability" problems than many of the cats with mast lengths less than 24'. So the cat sailors here look at the postings talking about the "problems" of having a mast in excess of 24' with bemusement.
