Our boat is normally stored dry, on the ground in a marina we pay. However, as we live surrounded by salt water channels, sometimes we prefer to have the boat at hand during the weekends, so the boats rests on the water several days, sometimes a week, but no more than 2 weeks. However, this is enough to start getting marine growth on the hull. I am thinking on applying antofouling, just to avoid the occassional dirty hull. I would like some advice on:<br /><br />a) somebody told me that if the antofouling is not in the water all the time it losses effect....is that true ???<br /><br />b) what is the best brand and/or characteristics I should look for ? (a cost estimate would also be useful)<br /><br />c) can it be applied by hand or does it requires an air compressor, painting gun, etc.....???<br /><br />d) what is the expected life under the conditions I mentioned ?<br /><br />Thanks a lot
