Re: New bottom coating perhaps?
I strongly suspect that something evolved from the super-hydrophobic materials will eventually be the future of bottom paints. The current stuff might work on day-launched vessels (though maybe not trailerables due to abrasions concerns).
Based upon the statement of "coated steel submerged for 30 days", I suspect that offshore racing boats would do OK since they sail frequently in conditions that would aerate (most of?) the hull. Then it becomes a matter of durability. Most cruising sailors, not so much...
