I think he meant the notches in the build form for frames 5 1/2 and 4. I just cut mine with a regular saw, slightly shallower than specified. Then final adjustments can be made with a chisel to get the frames exactly level.

I’m just about ready to order the plywood, do you all find an extra sheet or two extra sheets of quarter inch useful in case I mess up ? I’m having to get it shipped in so I’m going to order it all at once ..

It looks like I need around 10 to 12 sheets of 1/4 and 1 sheet of 3/4”

I think it's not too bad of an idea to get an extra sheet if you are having to get them shipped. I have seen cracked sheets (mainly on the Malahini in the aft section). It would suck to have to order just one sheet.

10 – 12 sheets seems like an awful lot for a Zip. Seems like I read somewhere that 7 sheets should cover it.

You should be able to easily get a transom and the stem/breasthook assembly from 1 sheet of 3/4".

I'd think 2 sheets should cover the side planking (1 sheet per side, cut in half lengthwise & joined).
3 sheets should easily take care of the bottom planking. A couple more sheets should take care of sub-deck and any remaining items.

I was expecting to order 7 or 8 for mine.

To answer your question, yes, I do believe it's a good idea to order 1 more sheet than you expect to use... just in case.

As far as 1/4 goes
So looking at this bill of materials it looks like 8 sheets are required if I am reading it right .using 4x8 sheets ..I’m thinking I’ll order one extra sheet to make the gussets and one extra sheet as a back up

One 3/4 should be plenty

Bill 3 should be plenty for bottom planking ? That would be great since it stated 14’ at 30” wide I was thinking it would need four

I’m glad you posted the screenshot of the B.O.M. 4 sheets would probably be safest. I think your estimation of 8 sheets is about right.

Even before adding an extra sheet “just in case,” I believe you’ll have plenty enough scrap to make gussets.

What type of plywood are you considering?

The meranti from Homestead is exactly what I used on my Utility.

I think Meranti looks nicer but okoume is easier to work with. Meranti is very splintery.

I too used meranti/hydrotek, loved the look, i highly recommend using fine tooth blades in a jigsaw for cutting it, 36tpi or more, pretty clean cuts with those, i bought cheapie Ace brand blades, ran them till they started cutting slow then pitched them, they're cheap!
I cut twice and it's still too short :mrgreen:

And precutting the face plys with a utility knife helps minimize splinter tear out. That trick worked great on my hydrotek meranti parts. It gave me a clean line to sand/trim to after cutting out the piece. Meranti is stiff but very strong, I recommend it for all the flat plywood pieces. Okoume is more flexible by comparison and works well for planking the hull.

The plywood was the single biggest investment in my build not counting the motor. You'll have a lot to keep you busy now!
