i was starting to think along those lines because we just could not get the mast to even break the surface of the water. the mast has been left erected all season so its difficult to say if it has water in it. Our season ends in a couple of weeks so i will be taking he mast down and i will check if the mast has water in it. If it has i will drain it like you said. Are there any particular places where the water is likley to be getting in? or could it be anywhere?
thanks for the info i will investigate and let you know f you are correct!
