Choosing a bottom paint for you boat is dependent on the ways in which you use and store your vessel. It's a task that needs to be addressed yearly, even if you've used a multi-season formula, it's smart to double check if it needs any touch ups.
We included some of the best copper-free alternatives for those who are eco-conscious. Total Boat Krypton and Pettit Ultima Eco both contain Econea which has been found to be an excellent biocide.
But you might require a copper paint if you're boating year round or in harsh conditions. You'll need a formula like the Total Boat Spartan which contains a higher percentage of copper, plus if you haul it for several weeks, the ablative property can be re-activated with a light sanding.
