Hot in January, hot and wet in February, wet and humid in March. As much as you probably have had enough boating over the summer months, the recent weather we are having on the East coast of Australia will give you the excuse to get back to your boat and dry her out. For many it is already too late, I heard a conversation on the club tender the other day, 'the engine was half underwater as the bilge pump stopped working' there is always something on a boat!
A sail came in last week to be cleaned, and the owner said he had only left it for a month, i'm afraid that that is all it takes in this climate.
If you are not going to be using your sails for any more that a month, then take them off the rig and store them below, and off the floor to just in case the bilge pump stops working.
Sail below, clean to crappy in just one month, and yes the sail is spotless again after Vacuwashing.
