Boat Forum / Cruising / October 2004Annoying problem -fixing cockpit flooring
My daysail boat open cockpit (Tempest22) floor is making cracking noise when I walk on it. There is small crack also.I patched the crack with fiberglass cloth. Now I have to solve the problem to prevent farther cracks. I 'm considering 2 options: Cover the floor with playwood and fiberglass over- details like non skid and glue between playwood and current flooring arise . Someone recommended applying expendable foam to seal the playwood to floor Second option is to re fiberglass with cloth and several layers , and fill the space between hull and floor with expendable foam to support the weight of the crew. I lean toward 2 option. please share your suggestions Thank you. Jari Is the floor suported by stringers/beams or is it floating.

Adding mass to the floor to prevent this will increase the weight quite substantially most solutions is to place/replace the stringers/beams if you have access to the underside of the floor, if not then my way would be to cut the floor out on the outer edges, glass in a new lip for the floor to rest on around the edges. While you have the floor out turn it upside down glass in some stringers useing some cardboard tube cut in half layed on the underside(now the top) once you have done that you can test it for strength while its out of the boat if your happy with it add glass mat and resin to the lip that you made in the cockpit and lower it back in pushing it firmly all around the edges add some weight and bingo floors done. The card board tube is for form not strenght so it can be as light as you can find. Place it roughly every eighteen inches in a box pattern across the underside of the floor with about 1/8 inch thick glassmat and resin. don't forget to leave a little space around the edges for your lip.The beuty of doing it this way is the floor looks original and with a bit of care the seam/join around the edge can be faired in and painted to hide any marks.

Follow -up question is how do I create this lip -Just mat and fiberglass using the same mat as for the stringers ? Also do I need to reinforce the edge on cut away floor before placing it back on new lip ? Thank you.

Jari If you cut about 50mm/2 inches in from the edge, the edge only needs to be flat glass/resin strips glassed onto the edge left behind,(glassed on the underside that you can now get too) The way to make FLAT glass strips is to get a sheet of window glass (the longer the glass the longer your strips)polish it and lay strips of glassmat/resin to about 1/16 inch thick, peel these off and cut to about 4"/100mm wide X long then glass in reinforcing the underside lip with more glass/mat. Now before you put the floor back in rough that shiny side up so it will bond. PRESTO shaun > Awsome. Australian solution beats all my stupid ideas. > Simple and permanent.

The foam "core" had rotted in the center because of a leak (crack in sole). I ripped the foam out and fit a couple pieces (to ease installation) of 3/4 marine ply, slathered well with thickened epoxy and screwed in place from above. After the epoxy kicked, I fixed and dressed up the crack in the cockpit sole. Solid as a rock. MMC > My daysail boat open cockpit (Tempest22) floor is making cracking noise > when I walk on it.

I just came after inspecting the boat once more.It seems to me that it will be ok to follow his instructions. Thankl you for the input. > Can you get to the underside?
