We often are asked, “How much water should my hull be taking on after a day out on the water”, in a perfect world the answer should be “none”! But in reality, the average fiberglass runabout will always take on at least some water. It can be a mystery as to where the water is coming in but remember it may also be coming in through the wet-deck from above, and in a lot of cases it can also be the seals on the hull bungs. This Silverline had the owner stumped for some time until he discovered that there was a nasty crack in the hull hiding behind one of the trailer rollers! So we rolled the boat back on the trailer for access and had a good look at this section of the hull. What we found was that the roller behind this one was also badly depressed and threatening to crack through as well. We then checked the opposite side of the boat to find the same signs so after consulting with the owner and getting his approval, we glassed up all four areas to reinforce. We also found that this area of the hull was foam-filled and the hull thickness was much lighter than the section nearer to the keel line hence the distortion. Because all the weight from the inboard engine is just forward of the transom adjacent to this area, there is a lot of load on these rollers. It is strange why the trailer wasn’t fitted with keel rollers down the center to support the weight better but certainly a suggestion for the owner to consider. We also noticed that the lower part of the roller assembly had two rollers whereas the top part only had one. If this could be reversed then the lighter section of the hull would have the load spread more evenly.
