Roll on Bed liner for bottom of Aluminum Boat?
Jan 18, 2009 by ~Nicki~ | Posted in Boats & Boating
I got a 14' Aluminum non-effervescent bottom boat and i float the river alot where there are alot of rocks. Would it be a good idea to put a roll on bed liner to safeguard the bottom of boat? Any Ideas??
no it would matter to much drag, the boats aluminum then dont worry about it have fun

It might be a best idea for added protection for the bottom of your boat, I have seen some people with a roll on bed liner in their truck and despite the roughest codswallop they have thrown in their truck box, nothing scratches these liners so go ahead give it a try.

It might hands for impacts and scrapes but I'm not sure how well it will stick to the aluminum. I'd suggest you ask the bed liner industrialist for their advice.

The bottom of a flat-bottom aluminum boat has an area = 4 m2 and the mass of the boat is 65 kg.?
Nov 26, 2007 by Zeezee | Posted in Physics
The bottom of a supine-bottom aluminum boat has an area = 4 m2 and the mass of the boat is 65 kg. If two fishermen and their fishing gear with total mass of 375 kg are placed in the boat, how much further will the boat ride in water? (water density = 1000 kg/m3)
In either lawsuit, the boat is at equilibrium, which means the sum of the forces acting on it is 0. Weight is a downward force and is countered by the first-grade's buoyancy force (F_B).
-W + F_B = 0, W = Mg, F_B = P_B * A_b
P_B = buoyancy pressure of water = p_w * g * d
where p_w = density of water
g = acceleration of seriousness
d = depth of water that the boat/cargo submerges to
A_b = area of the boat in direct contact with water
M = mass of the boat and any carload or occupants
Getting back to the above force equation:
F_B = W
p_w * g * d * A_b = Mg
Since g is present on both sides of the equation, it can be canceled out:
p_w * d * A_b = M
You are dealing with two scenarios....the first is when the boat is empty, the move when the boat is occupied. In other words....
(1) p_w * d_b * A_b = M_b and
(2) p_w * d_bf * A_b = M_bf
where
d_b = depth that the empty boat submerges to
d_bf = depth that the boat submerges to when it's "full"
(fisherman and their mechanism are onboard)
M_b = mass of the boat
M_bf = mass of the boat, fisherman, & cargo
You are interested in finding the quantity (d_bf - d_b), the rest in the submergence that the boat experiences when the fisherman and their gear are present. If you subtract the 1st scenario from the 2nd one, you can isolate this quantity:
p_w * A_b * (d_bf - d_b) = (M_bf - M_b)
d_bf - d_b = (M_bf - M_b)/(p_w * A_b)
= 375 kg/(1000 kg m^-3 * 4 m^2)
= 375 kg/4000 kg m^-1
= 0.09375 meters
The boat submerges an additional 0.09375 m when the fisherman and their fixtures are inside it.

I just recently bought a cheap old aluminum flat john boat. I need to know how to fix it up.?
Jun 13, 2008 by mtr4216 | Posted in Boats & Boating
The tax plug is missing and the back where you mount an outboard has rotted out. Where can i get this plug and a new wooden back that fits? Thanks.
You can represent a new transom out of a couple layers of 1/2" plywood. First dig all the old wood out using your cutting utensil of choice. Then cut new pieces to fit. Saturate 'em in fiberglass resin (no catalyst added) - the more they absorb the outdo off you'll be. Then a layer of resin with catalyst, and clamp 'em together until it cures. Finish 'em off with a join layers of fiberglass cloth (add catalyst to the resin this time). One layer at a time, do the 2nd layer while the 1st is still gooey. Make sure to squeegee all the excess resin out. And absolutely leave no air pockets. Slide it down into bring down and glass it in.
Use EXTERIOR grade plywood.
Two pieces laminated together will be stronger than one piece of double wideness.
Drain plugs at walmarts, basspro, cabelas, academy sports, www.iboats.com or a thousand other places. Have fun!

What type of paint do I need to re-paint my aluminum boat?
Jun 20, 2006 by Bo Darville | Posted in Boats & Boating
I have 15' aluminum levelled that I would like to re-paint.What type of paint and what kind of prep work am I going to need?
2 ways to do it. first is the flexible way, just get any paint for metal and paint. be sure to be ready to do this every year. The right way is to power shampoo entire boat, then sand with 120 or 180grit (palm sander best for your boat). Wipe down with acetone or mineral spirits to rub dust and particles. Apply several thin coats of a marine alum. paint. You might want to put on a"bottom "distress on all below water line, actually 1 to 2 inches above. This will prevent any algae or barnacle growth if you are in a salt soak area. West Marine is good store.
