Re: Keel cooling

We used Walter Keel Coolers on a series of 34' hydrographic survey launches for Canadian Fisheries and Oceans in the 90's. Since we were laying up hulls on site we built foam blocks as hull recessess so coolers would be flush, reducing drag. Worked great, but drag could be a serious issue for you at sailing speeds. Best to get some serious designer input here.
