The boat floor is arguably the most important part of your boat. If it rots, it can spread to the rest of the boat and create a terrible, dangerous mess. If it rots, it can spread to the rest of the boat and create a terrible, dangerous mess.
Re: Soft spot Repair or Whole floor??? Aruaco Plywood is good stuff. 1/2 " should be fine for the deck. If your stingers are bad 3/4" Transom use a 3/8" drill and do NOT drill all the way thru. From the inside drill down down low in several places about 1" deep (use masking tape on your bit to mark the depth).
Repairing a damaged floor in a boat begins with evaluating the extent of the damages. This allows you to generate a list of materials and assemble the tools needed to make the repairs. Some repairs can often be done without removing the seats or other accessories.
So, in case anyone is interested, this is what I did to repair two rather big soft spots on my deck (on each side where one mostly sits). 1. put masking tape on the whole area and mark the area. 2. drill small holes about two to three inches apart in the whole area (just through the top-layer of course).

Color match the gel coat to your boat, mix the hardener into the gel coat resin -- too little hardener is better than too much; if you err in the mix, err on the side of caution. Working from beneath the hole, inside the boat, use a paint brush to spread a layer of gel coat that's about the thickness of a toothpick onto the waxed counter top backer at the top of the hole.
If the floor is part of the boats hull, then take the boat out of the water ... allow it to dry completely. Check the wood with a knife/screwdriver etc.. to see if it is rotted/flaky. If so, replace the wood.
When noticing a soft spot on your boat, you need to add more support to the structure and reinforce it as much as possible. The soft spots tend to be small enough at first, so you need to make sure that the overall surface you are working on allows you to apply the epoxy and fiberglass properly.
Re: Soft Floor - Easy Fix? or too much trouble. If the floor is really that bad, I can't believe the stringers are in as good a shape as you believe. I'd suggest a little more investigation to the stringers, before you decide to just throw another layer of ply on the top for a quick fix.
Hello to all, I have a 18' bowrider, and in 2 or 3 spots the floor feels spongy, like it might be rotting out. I talked to some people and they...
Everything said above is true. If you buy a boat known to have a soft floor you should expect to spend a good deal of time and money to fix it. It took me about 3-4 months to replace the floor on the boat I bought. I knew it was soft going in but it was a really good price; the engine alone was worth more than I paid.
In boat repair circles it is a job for a professional yard-tear the old transom away and replace it. This is usually estimated at a cost somewhere between $2,000.00 and $5,000.00 or more depending on the size of the boat.
Tap the area around the soft spot with the butt-end of a screwdriver--a sharp sound is good, a hollow thud indicates a weak area. Mark the weak areas around the soft spot with a grease pencil, and include them in the perimeter of the hole you're going to cut in your deck.
It apears the soft spots are between the top fiberglass deck and the bottom side of the floor that meets the stringers. Basically saying the material between the fiberglass top and the bottom side of the deck is worn away.
The floor at the rear of the boat, in front of where the gas can hides, is soft. Someone has tried to repair it in the past by nailing down a sheet of plywood back there. However, the problem has obviously spread forward, as the floor ahead of the plywood is soft, too.
