Assume you will be using the camera on the boat some of the time. Might consider the Olympus SLR line. At least one of there cameras and lenses is water resistant. Not talking about there water proof point and shoot cameras but their SLR line. Seems typical SLR's have a magnetic attraction for errant waves and they don't live long after a dusting, BTDT. http://www.getolympus.com/us/en/digitalcameras/omd.html?icn=topnav&ici=camerasnav_omd
