An integrated thruster and ballast system in accordance with some examples herein may include a conduit disposed within a hull of the boat. The conduit includes a first opening in fluid communication with a body of water, a second opening in selective fluid communication with the body of water, and an outlet disposed within the boat. The integrated thruster and ballast system includes a ballast tank in selective fluid communication with the conduit via the outlet, a thruster disposed within the conduit and configured to move water through the conduit, a first valve disposed in the conduit and configured to selectively divide or establish the fluid communication between the conduit and the ballast tank; and a second valve disposed in the conduit and configured to selectively divide or establish the fluid communication between the second opening and the body of water.

A drainage device may include a channel body mountable on the surface proximate to an outlet on the surface and extendable away from the surface. A drainage device may include a groove formed along at least a partial length of the channel body. A drainage device may include a lip protruding from a bottom edge of the channel body at an end of the channel body that is distal from the surface when the drainage device is mounted thereon, wherein when the drainage device is mounted on the surface proximate to the outlet, fluid from the outlet is directed by the drainage device away from the surface.

A watercraft includes: a central frame; a deck supported by the central frame; and first and second lateral hulls laterally spaced apart from one another, the central frame being disposed at least in part laterally between the first and second lateral hulls. Each of the lateral hulls includes: a plurality of lower hull panels mounted to the central frame, at least part of an outer surface of each lower hull panel forming a running surface of the watercraft; a plurality of braces connected between the central frame, the plurality of lower hull panels and the deck; and at least one buoyant element received in and substantially filling a space defined between the lower hull panels and the deck. Each brace includes: an inner mount connected to the central frame, a lower mount connected to at least one lower hull panel, and an upper mount connected to the deck.
