Be glad to help if you want to go that way. If not and you want a self bailing boat and I don't like saying this I would raise the sole an 1" over plan.

I have to say that I have NO idea what PPI is. :help:

I definitely want this thing self bailing. Raising the sole doesn't bother me. :D Perhaps ignorance is bliss.

PPI means pounds per inch of draft. It reflects how many pounds is required to lower the draft 1 inch. The PPI of the OD18 as designed is 332 pounds.

AND it wouldn't have all the weight of the decks and console at that time. :doh:
Coast Guard uses concrete blocks and sand bags.

Seems to me if it's good enough for them ..........

You're not guessing at all.

The weight of the materials to be used is easily calculated. You're talking about 4 or 5 sheets of plywood, some fiberglass fabric, and epoxy, all of which have known weights.

Concrete blocks have known weights (depending on the block, and retailer or mason can tell you). Sandbag -- you can buy a known weight of designer sand at the big box, or use a bathroom scale to fill your own.

If that doesn't float your boat (pun intended) use water jugs --again dealing with a known weight.

Someone told me early in my build I could use 5 gallon buckets filled with water. Same principle as all those above. We want to see pictures when you get started. cottontop
