So was it your Mac26 that DRH photo'ed that day ?

As I said in the earlier post I hadn't seen that type of boat before and did a double take (looks like a powerboat but it's got a mast, WT?!?) when I saw one on-plane headed out of Alton Bay. Twas funny that DRH posted the pics he took just a few days later. Could that be Sleepers and Cub I's in the background ?
Going back to when I had 2 neurons to rub together and thinking about combining the (relative) lightness of powerboat with water ballasting for sail operation made me wonder if there wasn't another way to skin that cat. Keeping with the "lighter is better" philiosophy and substituting hydrodynamic force for ballast weight, has anyone tried a tabbed centerboard or swing keel-type centerboard in Mac ? I'm not sure how easy it would be to mechanize such an operation (swing keel probably practically impossible) on a removable centerboard but I'd bet some enterprising person could do (? has done ?) it. For that matter I wonder if conventional powerboat trim tabs (ala Bennett) wouldn't reduce the heeling enough to make up for any additional drag ? In any case I'll say purists cringing about how "un-great" the boat sails are like people complaining about how bad a flying pig would fly ... instead of marveling that a pig could fly at all.
