It's coming together nicely. We added a fixed t-top. If anyone knows where to get hinges for 1 1/4" tubing so we can fold it down if we need to, please let me know.

I'm not qualified to calculate that but since I've dropped out of college twice I think I can caculate it roughly as it's a flat bottom. A gallon of water weighs about 8.35 lbs. Let's say the bottom of your boat is 20' x 8' for an area of 160 sq ft. So using your guess of 2700lbs, and adding another 220lbs since I'm coming alongOriginally posted by FishNette View Post
your boat needs to displace 350 gallons of water to float. A gallon of water has a volume of 231 cubic inches, so you need to make a hole in the water about 46.79 cubic feet in the water to float in. With the area of your boat we decided on your draft would be about .292 feet or about 3.5 inches. Of course this is oversimplified and with the upslope of your boats nose you can be sure it's on the shallow side of accurate. I could come measure your boat and get you a better guess. Of course you likely remember how far off I was when I attempted to calculate the lifting power of an innertube so I probably wouldn't listen to me anyway.

Me too. The aluminum is about 80 lbs per sheet(4'x10'x.125"). We will probably use 5 full sheets, so 400 lbs of aluminum, 400 lb outboard motor, 700 lb boat hull, 300 lbs batteries and rigging. That's 1800 lbs. plus gear, fuel, and 3 people should put it at about 2700 lbs total.Originally posted by fishinganimal View Post
Does anyone here know how to caculate what the draft might be??Leave a comment:

Looking good!! Curious what you overall weight will be on completion.Leave a comment:

Thanks for your comments. I just hate to under power the boat or make it too heavy, either. It does have sponsons on the back which are quite large. I'm leaning toward a 115. The Galveston Bay Complex is quite large and I don't want to spend all of my time traveling at 25 or 30 mph. 40+mph would be great!

I think diamond plate might not be your best option. IMO a marine plywood floor painted with sand grit will give you much more traction and should save weight too. Just a thought. Looks like a cool old boat. Reminds me if the Ugly Mudda.Leave a comment:

Rollo is right about the speed thing.
Hauling azz at night even if you know your areas is a potentionaly dangerous thing.
Also I think fast flat hulled john boats are inherently dangerous at speed
I hung a 60hp on mine for this reason. It's light and still gets up on plane. I think now I could have done just fine with a 40hp
There is no good reason to add big hp to a flounder boat, even if you are thinking of adding sponsoons on the transome (Wich you should and will) to offset the weight of your outboard.
Keep thinking-keep it lite as possible.
With all the moneys save on the big out board could also be used towards a Vtwin honda and then reason I keep bringing up the Vtwin thing is my friend use to have a Vtwin on his boat. That engine could push the air hard, very rarely did we ever have to get out of the boat because we were stuck on a tire or something plus the Vtwin IDLES AND RUNS SMOOTH wereas my thumper has a lot of vibration when idled down to that sweet spot gig speed. All that vibration is hard on electronics, welds, light bulb filiments etc.
These are just my thoughts and I would have built a little different knowing what I do now.

Nice progress on the nose may have been a work boat once upon a time!....I like that yamaha 90 in a 2stroke for weight savings speed shouldnt be much of an issue the right prop would turn it on!!Leave a comment:
