I have a 1995 Chapparal 1930 BR that I picked up with a new 4.3L EFI Mercruiser. The boat appears to have been used as a rental boat and is pretty beat up and well worn interior. I upon investigating the rot around hull storage found some soft spots in the floor. I being curious ripped the interior and carpet out and found spots under the seats and in front of hull storage. I dug out the soft spots less than a foot in diameter and the stringers and underneath appear solid, hopefully caught it in time but won't know for sure till it comes out. I am wondering if I can cut a 4x8 down the center which will cover the middle from front to back? I then will use epoxy per the general consenus in flooring posts with marine grade plywood and follow up with paint. Since the sides are in good shape is there a need to replace the complete floor or can I proceed with just the plan above? I also smell fuel and may need to replace the gas tank. Thank goodness it is mechanicaly sound and the price was good. Then next year will need gelcoat at least on the bottom of the hull.
