Ocean-going vessels

A method of adding a flexible fuel tank within an inflatable hull of a watercraft comprising:

• a) gluing an open frame to the inflatable hull;
• b) cutting away the portion of the inflatable hull circumscribed by the open frame;
• c) passing a flexible fuel tank having a hose assembly coupled between the flexible tank and a mounting plate through the opening in the open frame into the inflatable hull;
• d) passing the hose assembly and mounting plate through the open frame into the inflatable hull;
• and,
• e) reorienting the mounting plate relative to the open frame and connecting the mounting plate to the open frame;
• wherein the inflatable hull has a plurality of separate inflatable compartments and a modular pressure control system comprising, for each two adjacent inflatable compartments:
• a pressure controller having:
• an air compressor coupled to each of the two adjacent inflatable compartments for supplying air to the inflatable compartments;
• a pressure sensor coupled to each of the two adjacent inflatable compartments for sensing pressure in each inflatable compartment;
• and,
• a deflation valve coupled to each of the two adjacent inflatable compartments for controllably allowing air to escape from each compartment responsive the an output of the respective pressure sensor;
• the air compressor and the deflation valves allowing the maintenance of desired pressures in the respective compartments.

• a) gluing an open frame to the inflatable hull;
• b) cutting away the portion of the inflatable hull circumscribed by the open frame;
• c) passing a flexible fuel tank having a hose assembly coupled between the flexible tank and a mounting plate though the opening in the open frame into the inflatable hull;
• d) passing the hose assembly and mounting plate though the open frame into the inflatable hull;
• and,
• e) reorienting the mounting plate relative to the open frame and connecting the mounting plate to the open frame;
• wherein the inflatable hull is part of a watercraft comprising:
• first and second hulls;
• and,
• a module adapted to carry a load above a water surface;
• the module being coupled to the first and second hulls by legs, each leg having at least two rotational joints therein allowing adjustment in the elevation of the module relative to the hulls and adjustment in the separation of the hulls.
