The emergency fire suppression controls
cooling water takeoff is from the jet unit, there is a risk some rubbish might get forced into the cooling system. This being the case, it is easy to check the strum boxes, which have plastic strainers, and clean them if required, eliminating the chance of wetting dry bilges. We also note the bright yellow screw caps float and are easy to spot if accidently dropped. Another plus is when the engines are shut down the water drains back into the jet units along with most of any debris trapped by the strainer. This is smart thinking. These platforms are also used to recover any potentially hazardous flotsam or a man overboard, although we have to say that like all fast ferries, it is highly unlikely a normally well- behaved passenger would fall from the vessel.
The starboard lazarette
Remote oil filtration
Most occasions on record can be attributed to skylarking drunks or, as sad as it might seem, a jumper who has had enough of life. Fortunately both incidents are rare, even though our crews still train for them. The Clipper IV's hulls are constructed au naturel of marine grade Sealium and left to weather and attain its own protective patina. The hulls are divided into five voids with a separate lazarette where the waterjets are, then the engineroom with the tank space. Moving for'ard, the for'ard void is largely clear and finally the collision bulkhead at the rear of the foc's'le void. Interestingly, in the tank void the main fuel tanks are separate, being a large 900 litre round tank rather than being built into the hull.
