When retrieving samples or gear from the water, sterndrives are excellent at staying out of the way. Combined with a swim step and an A-frame mounted on the transom, scientists can work alongside their payload without fear of colliding with an outboard’s upper unit. A “moon pool” on the aft deck of this 32’ vessel allows survey equipment to be lowered into the isolated water between the catamaran’s twin hulls, providing accurate readings and measurements. Inside the cabin, a head, small galley, workstations, and berths for two enable longer trips at sea, and less time away from the survey zone.
