SEDATION 4  Fuel Tanks installed

Two 60 gallon fuel tanks are installed under the floors of each hull for a total capacity of 240 gallons.  The hulls' Kevlar® reinforcement protects them from puncture in the event of collision.  Installation is in strict compliance with ABYC Standards, as are all systems aboard SEDATION 4, for safety and reliability.

Each tank is protected by 1/2" neoprene rubber pads to prevent abrasion and minimize shock vibration.

Clearance is provided to allow for 2% expansion of the tanks per manufacturer's recommendation.  Neoprene pads seperate the retention brackets from the tanks' surfaces.  Notice the string installed to facilitate running of the fuel sending unit wires after the floors are installed.

Provisions are made in stringers and bulkheads to permit unobtructed installation of fuel lines and fill/vent hoses without contact points which could induce chafing.

Watertight inspection hatches are provided for access to all fittings, sending units etc. in compliance with ABYC Standards.  The entire fuel system will be pressure-checked and certified leak-free per standard test procedures.

Tanks are permanently secured beneath the floors.  Here a mixture of resin and flox is being applied to the stringer tops before the floor panel is installed.  All edges and seams are then laminated with fiberglass cloth and resin.  Notice the neoprene pad atop the tank ... it will never contact the underside of the floor during normal operation but will limit tank movement to 1/2" in the unlikely event of capsize.
