This Markham Whaler powercat had a leaking Port fuel tank. The owner had started cutting out the old tank which had been built in below the aft deck. Making this more difficult, the tank had been foamed in with expansion foam. This we believe added to the shortened life of the alloy fuel tank due to trapped condensation and moisture. When we got the tank out it was too far gone and we decided to use a stainless tank similar to the ‘cruise-tank’ which with some mods would fit. You will notice that we had to build a raised section on the front end of the tank to allow for the height of the fittings. We also recommended to fit the new tank with a ‘soft-patch’ hatch which is a screwed down semi permanent lid but can be removed in the event the fuel tank needs to be replaced or repaired. The owner also requested us to reinforce the aft floor as it was quite springy which we then repainted. The new tank was strapped in and fitted with new fittings and plumbing. Other work was repairs around the bowrail mounts and repairs to the underwater section of the hulls. Some of the hull repairs were all the way through the hull skin from years of wear and tear. This boat was again in seaworthy condition and ready to go!
