If it's added buoyancy your trying to achieve you may want to look at the inflatable
bags that are installed on the "OPTIMIST" sailing dinghy.
They are installed forward of the midship thwart along the inside rail of the boat.
Granted the OPTIMIST is a tiny boat but maybe you could double up the number
of bags.
They are collapsible so when you're not using them they can be deflated to give you
more interior space.
I'm not sure who makes the bags but they should be no problem to locate.
the INTERNATIONAL OPTIMIST is the largest one design sailboat class in the
world.
 
Good Luck

Hi,

I checked into this for my 7' Fatty Knees dinghy also.  IIRC, the first
place I checked (Add-a-Bouy?) didn't make them anymore or was out of
business.  Then I got a link for another place, that I can't remember,
but that had a name that had something to do with "doggie."  I let that
go because it was going to be prohibitively expensive ($400?  $700?  it
was so expensive I immediately put it out of mind).

I also considered the fender idea that Howard describes, but I don't
have that many small fenders, so it had the disadvantage of being a bit
on the pricey side - unless you already have all the fenders and need a
place to store them ;-)  They're also slightly heavy. That idea still
lurks as an option though.

The idea I'm working on now (still in progress) involves two large
"pool noodles" -- the brightly-colored foam tubes kids play with.  This
spring Wal-Mart had some extra-fat ones for $5 apiece.  I bought a
couple and immediately rigged them up temporarily, just to try them
out, one just under each gunwale the length of the boat. They're
hollow, so you can run ropes through the middle.

The added flotation was amazing.  As in, you could just about stand on
the gunwales without tipping the dinghy or filling it with water.

The next thing I did was buy a couple of feet of clear hose and cut it
into ~6" lengths, which I jam fit into all the ends, to reinforce them.
  At this point you could use them as is, with perhaps one strap-eye
mounted below the middle section, to keep them from riding up.  I
haven't gotten this far yet.  Since I have some Sunbrella-type scraps,
I'm considering sewing some sleeves for them which would incorporate a
couple of tie down points.  We'll see.  This project is going
hand-in-hand with the one where I'm just adding a smaller gunwale pad
for everyday use.  I envision the noodles for snorkeling and/or heavy
loads in rough weather.

Were you thinking of this for your M-15 or for a dinghy?
