Abstract: A boat includes at least three trim devices positioned aft of the boat's transom. To improve the boat's ability to get on place, each trim device is initially positioned to a deployed position. The speed of the boat is then determined as the boat gains speed. When the speed of the boat exceeds a first predetermined threshold, the first trim device is moved from the deployed position to a non-deployed position. When the speed of the boat exceeds a second predetermined threshold, the second trim device is moved from the deployed position to a non-deployed position. When the speed of the boat exceeds a third predetermined threshold, the third trim device is moved from the deployed position to a non-deployed position. At least one of the first, second, and third predetermined thresholds is different from the other two of the first, second, and third predetermined thresholds.

Abstract: A temporary shelter having an inflatable, tubular base frame with inflatable, tubular wall support ribs fixedly attached thereto, the ribs converging to near an apex of the shelter. Flexible, water-resistant wall portions are fixedly attached to the tubular base and wall support ribs. The base frame, wall support ribs and wall covering form a domed structure when the base frame and support ribs are inflated.
