quality of your materials until the cost is no longer an impediment to
making your boat and still have a good chance of ending up with a
satisfying and successful build. OSB? probably not, but if all I could
afford was a punt made of CDX and finished with paint from the mistake
bin at Home Depot, I wouldn't hesitate to do it!

Jason--As you have observed, there is a diversity of opinion about the need to epoxy coat the inside of a boat. I can offer two inconclusive experiences.
I built a Bolger Sweet Pea with polyester coated fiber glass on the outside and painted with oil based porch enamel on the decks and interior. When not in use, the boat was stored upside down in the open on saw horses. The painted fir plywood checked and the "footballs" printed through the glass, but when I sold her after five years, there was no rot and last I heard, she was still in use (I sold her about 5 or six years ago).
I built a Michalak Mixer about four years ago. Being richer. I used okume plywood and epoxy. I built the boat because they were lowering the lake where I sail by 22 ft, the usual launch ramps weren' useable, and I wantd a small boat that I could drag down the shore to the water. The boat lives rightside up an a trailer with a not terribly watertight polytarp cover. I epoxyed and painted the inside and, though there is sometimes water in the boat, there is no rot--at least not yet.
I don't think there is much point to epoxying enclosed areas (though poorly ventilated areas may be subject to condensation). If you are confidant that your boat cover will keep all the water out, you can pass on epoxying the cockpit, but I haven't found such a cover yet.
Keeping water out of the boat is important, but so is protection from uv and good ventilation is also important.
In my old age and relative wealth (my children are self supporting), I feel that the materials which go into a boat are a small part of the overall cost, and for me it makes no sense to use anything but the very best. But as my experience with Sweet Pea demonstrates, a satisfactory boat with a long life can be constructed using economical materials. Keep whatever you build dry, clean, and well ventilated, and it will last a long time.

Subject: [bolger] interior epoxy coating?
I know the opinion varies widely on this but i'd like to here what
people think.
Is it worth it to coat the interior (below deck) of an enclosed boat
with epoxy (how many coats)? The flooding wells, all endgrain, chine
logs exterior hull and decks all have or will be coated. Is it a
waste to coat the rest since it will normally get no more than drips
and splashes through the hatch/companionway. The boat i has been
build with fir and MDO and i'd perfer for it not to rot out in the
next decade.......it has been build above disposable standards.
Just wondering......currently i'm planning on doing two coats and
then paint with some interlux brightside i have laying around.

Quote from Dave Carnell:
ENCAPSULATION
You will note that I have not mentioned epoxy encapsulation; i.e.,
coating both sides of everything with several coats of epoxy resin.
It has no advantages and is a waste of money and time that adds
useless weight. It won't turn lauan underlayment into marine
plywood, though it will make it cost nearly as much. It does not
keep the water out of the wood boat that lives in the water and a
dry sailed boat doesn't need it.

On my Micro the underside deck and mohogany supports are just bare
wood. No rot or signs of. One of these days I my coat it with to or
three coats of epoxy.

I think that is exactly contrary to what Bolger
recommends. Epoxy encapsulation is the way to go.

I recall that Bolger, Chapelle, Buehler
all oppose sealing the interior of the boat
with anything. Something to do with
air flow helping to avoid rot.

The underside of my Light Scooner decks are as naked as the day I
bought them and look more or less as fresh. No paint, no epoxy, and
they look fine. I have formed the opinion that a boat's greatest enemy
is UV.
