It would surely make the eventual job of fixing the sole (not floor) a lot harder and more expensive.

If you want to do a temporary band-aid I suggest you put a piece of marine or exterior plywood over he soft spot.

Just don't use the boat until you can fix it, you'll save enough money by not having to put fuel in it to do it sooner.

Plus your boat is weakend already by the rot and without any foam it will sink to the bottom so you have a failure or mishap, this could endanger your life and the lives of your passengers.

If you can't afford to maintain and repair your boat, you can't afford to own a boat.

The longer you own a boat the more you'll come to realize that last statement was the absolute truth.

Hopefully it won't be when your boat fails and sinks because you were operating it in disrepair while out on the water.

I didnt even reply to this thread yet !! ;)

Seriously .. JB had it right on. Just plank the spot with some wood and call it good.

Bondo had another valid question which would proceed all other questions/answers .. what boat are we talking about ?

The boat in question is a 1996 cajun 21 ft . It has an johnson 150 ocean pro that the vro failed and caused me to have to rebuild it( over winter). At great expence i might add, now this soft spot shows up.

Re: soft spot & boat foam

If it's a 1996 model, it should have flotation, unless someone removed it. USCG regulations. Maybe it just doesn't have any in the center, which is normal?

Floatation isn't required on boats over 20', although some of the better boat builders still install it on some of their models.

I would say the bottom line is that no reputable shop will do this for you. I dunno about the cost as Im sure any trunk slammer hack will do something for cash .. I dont know what the going rate is for trunk slamming repairs.

Best bet is to save your green backs and wait until you have a full prognosis of the damage that eventually needs to be correctly repaired.

Basically dont do anything until you know whats going on before you start propping up things for a quick fix.

Re: soft spot & boat foam

Do a search in the Restoration section for Cajun and you will find a few and a few taken completely apart. You will be amazed on where flotation is hidden and where the rotten wood hides too. Do the search and look at the pictures........

The bottom line is No One has agreed to your idea of just having foam pumped into it.

Boats rot from the inside (unseen areas) out...... when the rot reaches the decking it is a good sign of internal problems.

It's sad when a person realizes they may have an unplanned project boat regardless if they have owned it 10 years or 10 minutes.

Good luck with your project.

You should get some estimates for the pumping of foam into your boat, I think you'll be surprised at how expensive it is. I'd guess $800-$1200... then you'll have to rip out all of that foam when decide to fix the boat properly, a big waste of money.

The money you want to waste on your foam would pay or nearly pay for a proper restoration on your boat, something to think about.
