The owner of this tidy Cruise Craft Outsider booked this boat in for a transom replacement but got a lot more than he bargained for! He asked us to check out a soft spot in the floor which lead to us finding that most of his internal hull structure was rotted. To avoid any doubt we were instructed by the owner to “rip it all out” and replace it with composite and epoxy. The hull stringers ran into the half cabin below the bunks with the centre keelson running below the cabin sole, requiring the sole to also be removed and replaced. The bulkhead below the floor separating the cabin and aft deck was also rotted and replaced. The owner had 4 batteries stored in the cabin for his Minn Kota in the area originally housing the toilet however this was in the way and he asked us to build in a base each side below the bunks. This tidied up the batteries with them fitting into the space neatly. This was now a much bigger job than originally allowed for with the owner also requesting Eva decking laid on the new floor, sole, aft sections and side deck edges. We improved the way the under-floor fuel tank was installed and when we refitted it we updated the hoses and made a removable system to hold down the tank. Originally the tank was held down with an alloy Z-section each side which is screwed straight into the top of the main stringers which we believe is the main cause of letting moisture into the floor and stringers. This is a common system on boats and if you have this system either make sure the screws are well secured and sealed or opt for a different system. When installing the new hull stringers we always check the hull bottom panels for alignment and noticed that the Port side had an S bend down it, so with props and jacking we ensured this was straightened when the new stringers went in. A few other improvements were made to the drainage below the floor before fitting the new floor. This Cruise Craft is now fully upgraded with no timber in it anywhere, and should last indefinitely! The owner has reported back that the boat performs better with it jumping onto the plans much quicker and underway it rides level, which we put down to straightening up the Port side of the hull. He is looking forward to many more years of boating ahead!
