    Default 77 Daycruiser floor questions

    Hey guys, I have a '77 Diamond Daycruiser with 1 bad stringer (the right one, left in the picture), and another one on the way. I am about to start the process of replacing those, but I'm a little worried about what might be underneath them. I am afraid there might be a floor underneath as well that could be rotten, but I just can't tell. I see no wood grain anywhere under the fiberglass. My question is, could it be possible there is no wood floor? Or must there be a wood floor in a layup like this ? The resin looks really green on the floor - but I'm not sure if that is a product of age or an indication that there is wood underneath or what. Any insight would be greatly appreciated.

    you should be ok. the stringers typically sit in the recess/notch created by the strake shape. They will likely be sitting on the hull glass or maybe a shallow resin/putty bed. You could always cut out a small section of the glass wrapping the string to see for certain. If you want to get the stringers back in the same location to aid in reusing your hardware with minimal alteration you could make several stringer bucks to locate the new stringers in the exact same position. Use a fixed, un-altered structure like your outside stringers and/or the sides of the hull etc. to create a fixed point to locate off of.

    Thanks, why does the floor look so "green" though? Does the resin really just have that much green in it ? I'm still confused about whether there is a floor or not under there. I guess I'll just have to cut it up and see.

    I've heard that boat builders will spray a dark color (black or?) gel coat after all the colors go down in the mold to keep light from transmitting through lighter colors thereby distorting their hues. Pretty darn sure the only thing between the stringers and gel coat is fiber glass cloth and polyester resin. Looks like a fun project, good luck with it.

    Hmmmmmmmmmmmmmmmmmmmmmmmmmmmmmm & Diamond racer from the looks of things I can almost bet that your floor or the bottom of the hull has been Beefed up ( or - redone ) considering when ever we used AME# 4000 in are build at Skater the cure color was always green ,and not to mention that you will need to go to a big box store and get a little builders helper to figure out the degree of dead rise you have before cutting the new wood , and the putty used for bedding the new stringers in is called a fillet .

    Pretty sure there is no wood in the bottom of your boat. My 21' Howard doesn't have wood in the bottom.

    Ok that makes me feel better. I'm 99% sure there is no floor now. It seems very stout though. And, I believe my hull is a splash of a Howard.

    For the deadrise, are the stringers typically cut at an angle on the bottom to match, or is there a buildup of fiberglass/putty that they sit in (and thus cut flat on the bottom) ?

    I'm currently pondering how to support the bottom of the boat as to not warp anything.

    Thanks

    First off before hacking on everything might I suggest blocking up the transom , keel , chime , etc , to help keep everything ( hull ) as straight as possible .

    Thanks
    Typically ....yes the stringers are cut at an angle to match the bottom or dead-rise and a fillet is a coved - shaped application of thickened resin that bridges a gap or joint filling in all voids which also provides a great bedding compound for bonding stingers to the hull .
