It still floats thanks to the fibreglass skin the original builder added to the hull .All I did was rebuild the deck as well as I could using the plans posted on here.

Wow, nice boat! With that bottom there's got to be a speed where you pack enough air to fly! I see you have gone with the left hand throttle, real race boat style. I will be interested to see how your setup goes. With some of the bona fide race boats the propeller is so small the boat has to be held out of the water for take off, however I'm sure a smaller propeller would speed you up. It certainly worked on my Minimost. 

Looks good!

And another one hits the lake!, another one hits the lake!

I built it faithful to the original plans.

My boats only go in the water for the day.  I use an oil based paint(harder to do these days).

These are the most recent 3 hulls I have.

My brother in law built my first hull in shop class back in the seventies.  He had covered the intire hull will fiberglass resin with no cloth.  It was thick heavy and brittle.

After that one, I used the oil paint.  I've tried a variety of primers and have done without.  All with mixed results.  Have always had problems keeping the paint on the bottom.

The bottom just gets beat up.  My trailer bunk likes to scuff off paint.  The boat gets beached a lot and the waves grind it into the beach.  Then I get areas of paint that just decide to leave as I buzz around the lake.

The boat always looks best after a paint job.  After that they start to look like someone was having too much fun!

On this last paint job for the red boat I added a hardener used with automotive paint that I had left over.  Only put it on the bottom side.  Time will tell what it does.

All that said, I am not a painter.  If I don't want something to look like I painted it, I get a painter to do it.

My boats look like I painted them.

Have fun
