As promised, some new pics. Things have slowed down a little as the builders are on their Christmas break.
Roof is on
Interior-fuel tank cover has been screwed down. The tank itself sits in a sealed compartment known as a fuel cell. Fuel line runs to the transom via an alloy pipe which ensures that the watertight compartments stay that way. The circular cutout is over the tank filler cap - no airlock problems here as the tank is filled directly. No fuel gauge either - just a dipstick which has no moving or electrical components.
Stern shot showing port downrigger mount. The mount is elevated so that the DR can rotate 360 deg without fouling the grab rail. Also shows scuppers & access steps. Live bait tank is built into the transom. Overflow holes are along the top whilst the single hole lower down is the tank drain. Also shown is the bait station. This has a cutting board on the top level with drains both sides & a lower level to store tackle, pliers, etc. The bait station can be removed if a clear transom is needed for trolling.
