While I applaud your wanting to try and use a new material in foam. You are going to end up with a heavier boat than you would if you built in ply. The extra fiberglass and epoxy needed will add up fast. The cost will be 3 times or more, so I think that sort of busts your budget, but call Joel and ...

when I finish filling everything. I will put a 600g fiber.
you like?

Oh, I like it a bunch.

We are almost hitting 20F; so not tons of outside work. Mostly cabin and inside work now in the deep freeze here. My electric bill last month was $400. Beats renting a place tho.

I would like to ask you for the windows you used plexiglass or polycarbonate, what thickness. thanks

All the windows in the cabin are tempered glass. I think 1/4".

The other lites are polycarbonate; typ 3/8".

Most of the time a person is going to need to walk into the boat for stringer work and such. That load could result in changing the shape unless the bottom keel tapes are enough. All I am saying is there is a risk with light glass.

Thanks guys, I appreciate all of this. The reason for theoretically using all 3/4” foam is very simple....volume discounts from my local supplier. My cost on 7 sheets of 3/4 would be less than a combo of various sizes (the price break is at 5 uniform sheets). In theory the thicker foam would also h...

You may need to install rubrails or beef up the top edge of the gunwhale. I do not know how Jacques is dealing with the flip question in his foam book, but a foam boat is very floppy and can lose shape easily when removed from the jig. It may require a temporary bottom jig even to avoid getting the ...

For either of those boats 3/4 H80 is way over kill for the sides. The bottom takes the stress and the sides keep the water out. well they do more than that but you get the point. I would probably use something like 3/8 H60 for the sides. If you go foam I think JM would give you a lamination schedul...

The main thing to reconcile is how will the foam be supported throighout the build and how can you flip wothout shape loss.

How do you plan to build and flip and what will hold the hull shape diring the flip. Eye trouble at noght for me so I do my best.
