condensation under boat cover

[dnardy]

Hi all,

I have just bought my first boat, unfortunately I won’t have a shed to put it under for a few months.

I have bought an Ocean South cover that fits OK, but noticed a lot of condensation under the cover and in the boat in this weather. Has anyone found a way to combat this? Or are there covers made of different material that handle this better?

They say they're breathable so to my way of thinking there should be minimal condensation in boat.

You could try propping up one corner to let air in/out.

Other than that can't help, you can but try it.

You could use a bilge blower to dry out the boat when you put the cover on.

Under floor ventilating is actually very important, it is where all boats will fail in the end.

The quicker you can dry out your boat the less corrosion and decay will occur.

I leave all my hatches open for a week after a run and clean, I stripped the boat out a month ago to see underfloor and there is no sign of corrosion anywhere yet after two years of fairly wet saltwater use...esp with cast nets gathering bait.

Keeping the underfloor area dry is very important. If everything is not completely dry before you cover the boat you will only seal in moisture by covering the boat.

Bungs out, boat drained, hatches open etc. Preferably dry well in the sun before covering. 

A mate of mine uses a small vent fan to maintain airflow.

If possible, raise an edge in the front and also the back of the boat, that will let any breeze through and still keep the rain out. Any breeze going through should help with the problem of condensation not forming.
