Thanks for everyone who has replied.

Seem like this is a good idea to buy Lysol concentrate, mixing it in a
garden sprayer and spray the interior of the boat and the underside of
the boat cover. This is something that I will definitely try when
spring comes.

Another option are mildew packets available at West Marine. However,
you would have to air out the boat before using it as the fumes are toxic.

Thanks for the idea. I will see which option is the most practical for
my need.

Adding a vent to the boat cover sounds like a good idea to cool the
boat cover to extend the useful life of the boat cover, and also to
help air circulation. I am just not sure exactly how to add a vent to
the boat cover that I have already been using (as comparing to order
the vents as an option in the process of ordering a new boat cover).
Seem like the actual implementation of this idea can be difficult. Oh
well...

As of buying breathable material for boat cover, I cannot do this. The
reason is that the boat has a T-top and I have a hard time finding any
boat cover that fit over the T-top. In fact, I am counting myself as
lucky when I find the expensive vinyl boat cover ($575) that can cover
a boat with a T-top.

You could get a sunbrella cover tailored to fit your boat. True it
would be expensive, but it will last more seasons that a vinyl
cover, and eventually make up for a lot of the expense. Plus it
will fit better with less chance of wind damage.

True. If I would be buying a new boat cover today, I likely would ask
someone to custom tailor it for my boat to account for the T-top, and
to add vents in it, and to use one of those breathable material. But I
was in a hurry to get a boat cover to cover the boat before the winter
comes (I bought the boat very late in the season). Therefore, I didn't
explore that option. I guess I will have to wait many years before I
will take advantage of this option.
