Hello to everyone. I am new to this site and would like some information on construction techniques used by Sea Ray to build sport boats. I recently purchased a 1990 20 foot cuddy cabin and discovered some rotten wood on either side of the fuel tank area. I assume that the wood on either long side of the fuel tank are part of the stringer system but would like to confirm that before I go through the bother of removing a full fuel tank and part of the deck.
The structure seems to have a ½” x 3” x 48” piece of fiberglassed plywood laminated to a ½:” x 6” piece of plywood that goes from the bulkhead (in front of the motor) in the bilge area to somewhere forward of the fuel tank panel. This piece of plywood appears to be laminated to a piece of sideways “Z” shaped something (foam perhaps) which has been laminated with chopped fiberglass. I need to replace a 12” section of the laminated plywood on both sides of the fuel tank about 12” away from the bilge bulkhead. I would like to know if the plywood is in fact the stringer and therefore is a structural member. I would also like to know if this boat has a wooden core hull, or if it is just formed fiberglass.
One other mystery before I remove some of the decking. I’m not sure what the “Z” shaped form is for. It appears that the deck on either side of the fuel tank area extends over the void from the sideways “Z” shape and meets the top of the 6” plywood strip. I would like to know what is immediately below the deck so I know where I can cut, and also how I should build the area back up to support the deck.
I appreciate any help you can give me. I couldn’t find this information in the forums anywhere, but if it is there please provide a link.
Thanks.
