Just about all the systems in Fortuna II were replaced. I include a small selection of items that may be of some interest.
Propulsion
The old fuel and water tanks came out
And the new ones went in
The old engine came out
Exposing a slurry beneath the drip tray that had to be dug out
Which allowed me to lower the engine beds for the new engine
Leaving lots of space for the new engine to sit
The engine is a FPT N67 150 supplied by Lancing Marine. The two 450 litre fuel tanks are operated independently, each with its own filtration system.

A new (more powerful) engine needs, of course, a new prop-shaft and more powerful prop
As a long keeled single screw vessel with plenty of windage Fortuna II is not the ideal boat to maneuver around inside marinas. After some consideration we decided to fit a bow-thruster. I persuaded Ian Bowles to laminate up flanges to a standard cut down fibreglass tube to make a ‘drop-in-and-bolt-in’ tunnel to fit the inside face of the planking and I bedded and bolted the assembly in. Although we had to remove part of one frame to allow for the installation, the tunnel itself provided much more strength than the removed section of frame.

Electrical
The electrical design, planning and installation was done by Chris Rothwell. The end result was, everyone thought, rather good. Most of the electronics are SIMRAD with a single 12″ display used to access charts, radar, AIS and the docking camera.
Wiring up the loom
There were, of course, a large number of wires to pull through

We have power!
Water
Grey water from the galley, heads basin and shower is collected in a small sump and pumped out through a single below waterline through hull.
Black water is either stored in a holding tank or, via a diverter, discharged overboard.
The holding tank and associated pipework diverters occupy what was a decent sized hanging locker in the fo’c’sle.
Cooking & Heating
Fortuna II carries no gas (and no Petrol for that matter). Cooking and heating is diesel taken from the main fuel tank. The Wallas oven and hob provide an explosive-safe cooking and heating solution.

Ground Tackle
Fortuna II’s numerous CQR anchors were replaced with a Rocna 33 bower anchor and Fortress kedge. The Rocna required a re-designed stemhead fitting to enable launching and recovery. A low profile Lofrans windlass is sited on the foredeck obscuring as little of the view ahead as is possible.
