My understanding is that it mainly depends on whether the oak is white oak, or red oak. Apparently, red oak is not particularly rot resistant, whereas white oak is a very good (if heavy) wood for boatbuilding.

From my reading of the text, wood needs four properties to be suitable for marine use.

It has to be strong enough for the application.
It should exhibit adequate rot resistance. (This will mean very different things to larger boats which stay on the water in a slip than it does for smaller trailered boats which are on the water for a few hours at a time.)
It must be able to hold fasteners under pressure (You don't want screws stripping the wood out.)
It must be able to bond well with adhesives. (Oily woods or those that easily delaminate are therefore not desired.)

There are other concerns as well, such as workability. Spintery Douglas Fir is harder to work than mahogany for example.

It really depends on the boat you are building and how it is designed/engineered. I would think that a stitch and glue boat would be more sensitive to adhesives holding firm than some of the frame and skin boats. I would also argue that the high performance V-8 speed boat like a Rampage would demand more from the wood in all areas than a Utility with 15HP outboard.

There are several boats in the catalog that I would happily build from red oak or even quality pine with some modifications. Others..., not so much.

Perhaps the slowest Zip build in Glen-L history...

:D I used a lot of red oak for framing and battons and shears.was happy with the screw holding aspect as well as the bending although cut it thinner and laminated more.I also used quite a bit of cpes on it.since it's so porous,it just sucked up the cpes.Its like what others have said-it depends on your usage.My boat will probably go just 6 or 7 mph.I wouldn't trust red oak in a speedboat.

Well crud. I guess I missed the red oak v. white oak class.

Here's a great video explanation I found this morning: https://www.youtube.com/watch?v=L6t2AZubF8U

I only used it for trim pieces and it's encapsulated with epoxy so it shouldn't cause too many problems with my tubby build.

I have used the okoume ply from Berlin G Myers for my Malahini. Beautiful, wonderful to work with and worth the cost. My sapele lumber I ordered from the store in Michigan that Roberta reccomended, I think Johnson's. Also wonderful to work with and beautiful under epoxy. Cheaper to ship from Michigan than to buy in Summerville!

Well, I know it's not recommended but I built my TNT using 100% lumber from Lowes. I used a mixture of Douglas Fir, Southern Yellow Pine and exterior plywood. I did fiberglass the whole exterior and sealed everything inside.
My boat stays in the garage except for when we take it to the lake and I dry everything after every outing.
If I was going to build a boat that spent more time in the water and outside I would use all marine grade wood.

I picked up 3/4" marine ply from Southern Lumber off King for $101 w/ tax. I will end up getting sapele from there, it's about $7 bdft, is that cheaper than what you got from Michigan? I will have to go to Berlin G for the Okoume 1/4 ply for the hull.

My friend did the same. His Victory weighs a ton, but he doesn't care. He's had it for years and rides it in salt water. No leaks, no problems.

I would really like to see some photos of your friend's Victory, if you have any to share. I studied that design, as well as a few other William Jackson designs, before deciding on the ZIP for my next boat.

Anyway, I'd like to see how your friend's boat turned out!

Alright! Next time I head over there to take the boat out, I will take some pictures.

Here are a few pictures from his build.

Thank you for posting those pictures! It looks like your friend modified the design a little bit, around the sheers... I'm guessing raised bulwarks, so he'd have a little more freeboard for using it on the coast?

Thanks again for posting these!

Which brings up another question. I've been looking at motors and one mentioned that it was "freshwater only", I didn't know there was a difference. Is there a problem me putting the boat in freshwater and saltwater? I just figured if I would rinse it well at the end of the day, all should be fine.

I'm not certain about this, but perhaps the seller of the motor is describing it as "freshwater only" to state that it has never been used in saltwater.... therefore, the motor has not been subjected to saltwater corrosion?
