when I built my first mouse I didn't trust it, I took it to a pond most people didn't know about and launched it out of sight of everybody, IT FLOATED

!!! I paddled it around a bit to see how it handled, then had someone who had just showed up snap a picture.
The hull was bare plywood at that point so I stapled plastic around the hull and went for a longer paddle, besides being over loaded the boat wanted to wander, badly.
Before I handed it over to my daughter for her first paddle I made sure it had a good skeg, (kind of like a fin on a surfboard) the difference is night and day.
I wasn't sure how to stick a skeg onto the foamie mouse, I ended up shaping a scrap of foam to the shape of the hull bottom, glued it on with GG, and immediatly had all kinds of mental pictures of the skeg snapping off.
I then added a "frame" of plywood to the skeg foam. the vertical piece keeps the skeg from bending and snapping, the horizontal piece is a skid shoe, for all those hidden rocks and logs.
I had to fill a larger void in the back of the skeg so I used GS, otherwise GG.
Some gravity clamps, drywall screws and duct tape to control the bond and ooze out.

the end result was a bit rough, but I don't consider a glue joint solid unless the glue oozes out.

a bit of work with the orbital sander to smooth things out

then I layerd on the fabric, three or four layers thick on the skid shoe section and two thick for the rest.

I picked up a gallon of mis-tint Glidden porch and floor paint at the depot, $9, it is a great color for filling the weave, otherwise I hate it!

(I also got a 5 gallon pail of exterior mis-tint paint for $30)

don't tell anybody, if everything works out, this weekend I will sacrifice my self for the sake of foamies everywhere and attempt to defy gravity on the pond behind my parents house with the mouse.....

just got to pray for some nice weather, last year I had a boat to launch and it

rained for our big family weekend. My sister is bringing her carload of kids and we're bringing kids and the fleet, should be fun!
