New Boat Build Project - (Totally Rebuilding An Older Boat)

[jamesmusslewhite]

Well finally after all these years of buying the boat, tearing it completely down and waiting for the time when we had saved the funds and were in the position to actually start the rebuild we are finally nailing on the plywood on the outer-side of the hull. Snif, it is finally starting to look like boat after looking a wooden skeleton or yard-art, I'm so proud I almost have tears.

 

 

As the plywood has been properly cut to the needed size and shape we start start by applying epoxy to the outside surface of the hull frame. Then the piece of plywood is held into place and tack-nailed into place. Then the center of the rib as well as the location of the middle rail are lined with a straight edge and a pencil and then tick-marks are made on these pencil lines every 2-1/2 inches, This is so it will be easier to nail and maintain the even spacing of the brass nails while standing.

Well that's 16 foot of the old girl properly measured, cut, epoxied and nailed. And so far no mistakes and everything lined-up perfectly.

I had thought about using PVC pipe instead of bamboo for the wings as the PVC would seem to hold up better under the constant contact with the water, but would still use bamboo for the outriggers which secure the wings. It seems like thick walled (high water presser) 4'' or 6'' PVC pipe would work well for the wings of a pumpboat this size. I have even looked around here but have only seen thin walled PVC pipe would work quite well for this task. I admit I have never seen it done before in the Philippines, but that is not to say that it would not work quite well and nobody has just thought to use PVC pipes instrad of bamboo. It is all a matter of water displacement after all. A 55gal plastic drum displaces 470.3 lbs meaning it will hold 470.3 ponds of dead weight above the waterline.

 

When figuring water displacement the follow formula would apply to a 55gal plastic drum;

A cubic foot of water weighs 64.42796 pounds. A 55 gallon drum would displace about 7.3 cubic feet. 7.3 times 64.42796 = 470.3 lbs

(does not include the buoyancy of plastics used in drum construction). One only needs to take the I.D. measurements of a hollow object to determine Cubit foot of hollow space and multiply by 64.42796 (if container in non-buoyant, then deduct the total weight of the container). This will come in handy if your wanting to design any floating projects such as decks and platforms and want to know how many and what size containers will be need to keep the construction above the water line. Remember to also equate all objects expected to be added to the weight of the construction such as people, supplies or other objects, then add additional container sufficient to handle the additional weight. This also applies when calculating the safe number of people in a boat.

I always loved the look of the Hawaiian outriggers and wings. Talking about being able to pimp-out your ride...

Roger that Gunny about displacement.  It still amazes me how a Missouri class battleship can stay afloat.  Regarding that tricked out Hawaiian outrigger, it looks like fiberglass-epoxy like the skin of a surfboard.  Can that be applied to your boat?  Well, at least re-enforce the bottom hull and all the stress points on the outrigging and wings?

Well not to this one as I already have the materials for the outriggers. But, I just might try to start another build on a 36 footer and a modified version of these ourriggers sure would look really good on that one. It would be a head turner...

:thumbs-up-smile:

Perhaps like this one?  I'll come over with some beer and good times -- we'll probably get lost at sea......he, he.

Well she is officially a boat as the plywood skin is being cut and nailed in place and though the boat at this stage of construction is not yet painted, she can no longer be classified as merely being 'Yard Art'.

Applying epoxy to the outside surfaces before the piece of plywood is put into place and nailed.

 

[jamesmusslewhite]

The epoxy is smeared thickly on all outside surfaces of the hull frame as each piece of plywood has been carefully measured, cut and held in place to insure a perfect fit. Then the pieces of plywood are nailed with brass nails.
