Freezing water in Australia .... not ...
No, I can categorically state that it was not freezing water that caused the problem - the boat was originally in South Australia on the coast and there is definitely never water freezes there (nor here in Western Australia).In Perth we are in the middle of winter and the sea temperature is 18 C (that's 64 F on the silly scale).I am also thinking that the damage may be the result of too much weigth on the keel whilst on the trailer? Perhaps the port and startboard bearers need raising?And to answer soling42 - yes, there are lots of wonderful sailing opportunities in Fremantle in winter - one just needs to pick the day - and today is not one of them with winds "W/NW winds 20/30 knots with possible thunderstorm squalls to 45 knot". But air temp is a comfortable 18 C too.That said, in summer we get typically get quite strong afternoon sea breezes so sailing in 20-25 knots is not unusual.
