Jealous!
I have access to a couple of free old sunfish that I could convert but unfortunately don't have time or space to store another boat.
I can help with pic uploads, should be able to access my email via my profile. send them to me and i will post them.

Thanks for the offer Carl! I figured it out.


So the next question for this build, do i put the motor board at a 12* angle or mount it flush to the transom?

Its a displacement hull, that is going to most likely sit heavy in the stern. Maybe a flot test before i mount the motor board.

I took inspiration from Mr. Sanford?s Gilgo gunning box

Pretty interesting conversion!

What size motor were you thinking?

Also, what did you use to seal the sides of the rear sponsons?

I have a 5hp merc 2 stroke for it.


For the rear pods as ive been calling them:

Filled each with 2lb floatation foam.
I then used 1/4? marine plywood (coated in epoxy) to close them up.
Three screws and 5200 to keep in place.
Sealed with glass and resin.

Pete when you launch her take more videos and give us a update on how she does.

Pete,

I have a Sunfish hull I was considering making into a layout boat. I just don't need another boat to work on right now though. If we get the urge to go after sea ducks I might do it.

I like the motorwell concept. Most I have seen cut the last 2 feet off the hull and lose the potential flotation. Think you will need abit more power but my first sneakboat had a 4 hp.

At this stage I would lather up the exposed plywood surfaces with epoxy to seal it and float test it before you go to far. See how it trims out with you and the motor and approximate load. Right now it's a guess. My concern would be given it's a sailboat hull it may squat in the stern a bit. my 2 cents

Yes thats the plan. All wood will be epoxied and or glassed

Here is another boat that i took some ideas from.

The video shows it works for this builder.

Good morning, Pete~


Nice work all around. As you note, she's essentially a displacement hull - with lots of rocker in her keel. I expect a 3 - 5 horse will be just the ticket. Not fast - but steady and not stern heavy.


All the best,

This is looking great! Nice work.

There's one for sale down the road from me...wish I had the time and funds for another project. Looking forward to seeing yours come together.

Just for future reference, if someone is looking for a hull, I think a Laser would be a better choice as it is more of a planning hull. Though they are hard to find cheap.

Have you thought of using thickened epoxy in place of the 5200? Its a lot cheaper and its hard the next day.
