The present disclosure is directed to a boat having a self-propelled watertight intermediate propulsion section, a watertight bow section connectable to the front of the intermediate section, a stern section connectable to the rear of said bow and intermediate section and the stern section being watertight and buoyant and having steel flat bar framing outlining the perimeter of their transverse extremities welded to the end of each said section which it abuts. Spaced openings are drilled through the flat bar framing in alignment with each section for being selectively joined by bolts and nuts to make up a boat of variable length of bolted abutting sections. A watertight bulkhead is set back from the flat bar framing and water-tight sealant means having openings in alignment with the flat bar openings of each section which makes up a water-tight modular craft of any combination of sections forwardly and rearwardly of the self-propelled intermediate propulsion section having longitudinal rigidity from bow to stern and the sections have utility for various activities such as pushing barges, towing barges, working around bridges, oystering, shrimping and the ferrying of vehicles. Each of the bow and stern sections being especially adapted for a specific activity and being selectively addable to or removable from the intermediate propulsion section to permit qualified licensed ship handlers of craft of varying length to operate a craft within their licensed length.
