C-Voyager's 24" hull extension

Dave, this has been very interesting following the progress of C-Voyager... really enjoy your "can do" attitude. Knowing you, there wasn't a doubt in my mind that you'd make this happen. You da man!

Best wishes,
Jim
 
Amazing. So, the overlap of the fiberglass will be strong enough? I
guess a lot of strength is picked up by the fact that you are dealing with
a laminated core, right?

All new wires run on Shelly IV will be an extra 24" in length :-)

Mike – I think it will be strong enough.

It turned out like I had planned except where the stern met the extension on the side at the bottom. Because of the design of the boat we will have to fill in that area about 3/8th of an inch and tapering it to the front and rear about 11 inches.

While everybody thinks the C-Dory hull is flat in the rear, it is not. The bottom is curved from front to rear. The last 2-1/2 to 3 ft of the bottom of the hull curves up more than 1-1/2 inches. From what limited knowledge I have of boats, I would think this would cause the bow to rise. So when I lengthened my hull, I opened the top 5/8th of an inch more than the bottom. Now the up sweep of the stern is about 1/2 inch. I am tempted to go into the boat building business.

There are more photos in my album.

Well now I have figured out what started this project in the first place. It didn't come to me until you posted this picture:

I had wondered how and why you would have jumped into such a project but it is all quite clear now.....You must have been the
person who sparked Hollywood's Billy Bob Throton and his new movie The Astronaut Farmer.

The boat looks close to ready for lift off and I am sure as soon as you install the Rocket Motors you will be the first to put a C-Dory into orbit.

Good Luck ...and "Gods Speed John Glenn"
 
Dave - It could be that the aft curvature was there to help reduce wetted surface area when on a plane. I guess that would lift the bow, but weren't the old river Dories curved like that too?

Anyway, I am amazed at what a great job you've done on that boat!

The amount of fore to aft curvature is called "Rocker"--some dories are flat bottom and some had quite a bit of rocker. For example the drift boats used on Western US rivers have a lot of rocker. A Glouster dory does not have much rocker.
 
We decided to turn the boat over today. It was too hard working overhead. Should be much faster and be able to do a better job.

What we have done with and to the boat speaks volumes on the ruggedness and quality of construction for the C-Dory. The tires in this photo are not holding much weight of the boat. They are to keep the boat from rocking when someone is on the boat.

Again I have added more photos to my album

What an amazing project! My hat is off to you :thup , Every time I look at this thread I'm just amazed by the pictures. First your boat cut in half, now it turned turtle :shock: . I'm trying to imagine other things most people would never dream of doing to their boat just to get an idea of what's other possible surprises you might have up your sleeve. I can't wait to see this when it's done.

Damn, Dave!

That sure looks like an E-TICKET ride!

How many guys can say their C-Dory has done a loop-d-loop?

By the way, how come every time we get a new photo of your boat there's a new, different guy working on it???

Must be paying out a lot in wages to this multi-talented work force!

Could it be that your really a Fortune 500 billionaire incognito?

Always thought it might just be simpler to BUY a new, longer boat, than to perform a Houdini Saw The Girl In Half and Make Her Whole Again Miracle. Maybe you should rename the boat "Houdini's Girl"?

Great job, fun poking at ya'!

Joe.

Omazing piece of work there, it's starting to look like a boat again. I'll bet you've had a few "hold your breath" moments last last few weeks
 
well it just amazes me how you have flipped her and the cabin and railling is still their .. really impressive .... with the pic's the ring on the bow post is takeing most of the weight ??? the project is really a eye opener ... wc
 
Dave, how much did you overlap the added section, side and bottom, at each end to take the bending forces when the hull hits a couple of waves? The work looks great.

Boris
 
All C-Brats – Thank all of you for the complements on my project and the encouragement.

To flip the boat we lifted the bow with the bow ring, and then started rolling it from the stern slowly, on the tires. Mike raised and lowered the bow as the boat went over so the cabin never touched the floor. I have to admit, I had a little apprehension about the bow ring when the boat was sideways. Now I believe you could hang the boat by the bow ring.

Joe – the fellow with all the hair and beard is my brother (Mike), he works for nothing. He will do a lot of the metal fabrication (bow rail, fuel tanks, top shelf and generator platform). He use to build and modify boats in Alaska (big ones 60 to 120 footers, not little ones like this). The man in the white suit is Ben Toland.

Boris – the overlap with the balsa core is four inches on each end. As seen in this photo. Inside the hull the fiberglass overlaps that another inch or so. Outside the hull, it will overlap just enough to blend in the seams and that will be about an inch except where it took some grinding or filling to blend in the seams.
