We were asked to carry out repairs on what was thought to be a Mako hull however we have since found out this unmarked hull was in fact a Bertram V19. This boat has been converted to a center console and was a neat set-up. Unfortunately the hull had some real problems down the back where the owner found a rotten sub bulkhead which had caused some serious cracking in the hull. The owner also wanted to move the under-floor fuel tank forward this required some modifications to make it fit. What was decided was to add a couple of new sub bulkheads, reinforce the keel stringer where it was cut down for the tank and extend the keel stringer aft to close to the transom. This aft panel was where most of the hull cracking was and had very little support. One area just forward of the rotted bulkhead had cracked right through the hull and needed the hull glass re-built in this section. All new work was done using epoxy for maximum strength and adhesion.
The owner has since taken the boat for its first run and reports that it handles much better with the fuel tank further forward and even goes faster!
