CVZ-18 restore thread...part 2

[dorelse]

Ok, looks like the original thread rolled off...shoot!

Chicken or the Egg time question:

My goal before Winter sets in officially is to get the motor in and started...I can clean up the electrical over the winter & early spring.

I'm thinking of putting the motor in and leaving the flotation boxes as is until next fall...they can't do any more harm then they already have, plus they're dried out...core samples are showing them dry.

If I take them out now, my concern is that I'd have to make 'ribs' or something to support the gunwales before the engine could go in for fear the weight of the engine would tweak the upper hull.

Of course...this being a 3 day weekend, I could get a lot done in a short amount of time too...thoughts?

[Rosscoe]

I would think it would be much easier to do that work before the motor goes in, wouldnt you?
Do what you want back there while you have the room?
Maybe take most of it out and leave the part that is perpendicular to the gunwales? I dont know. I honestly do not know what kind of support they offer anyways.
Shorty?

[CVX Fever]

Andy Edson had some supports put in on his CVX18(Same hull) to stiffen up the hull sides after pulling out the flotation boxes.

If your intent is to get it running and then sell I'd leave the flotation boxes just the way they are. Especially considering they have dried out and aren't rotted. Why make more work for yourself? Removing them won't add a penny to the value of that boat or make it easier to sell.

If I go through the effort of installing the motor in Goldie, get it on the water, then it won't be for sale (probably ever)...so I'm planning to do it 'right'...not 'good enough' to get it to sell.

They probably don't do anything for structure...wrong kind of foam density isn't it...good point Rosscoe..

Allan (Green with Envy), and my 13 yo both think its a good father/son project, so that's what its going to be.

[dorelse]

Got up today and decided to get 'after it'...tore both boxes out.

Well, so much for my core tests...the boxes were soaked at the bottom!  I'm glad I took them out...and to be honest...I just can't see putting them back in...there's so much room back there!  We'll see after the motor is in...but, I'm glad that's done.

Painted the bilge with Bilgekote:





Look at all the wet foam:

Having pulled the starter out (and worse yet putting it back in ) more than once in my CVX I agree with you.  I actually had to remove the manifold (and bench seat with attached engine and side covers ) just to allow enough room for me to squeeze in their.  I have thought about doing a mod on mine someday to make the flotation boxes removable for easier engine access when you need to do engine work.  Some other make/model boats of the day had a simple engine hatch that you pop off for easy engine access not sure why Carlson's didn't come factory with same or similar design.

[Rosscoe]

So did you decide they werent providing any structural support or get some feed back from someone?
Yeah, lots of room now! So were those boxes supposedly sufficient in size to keep the boat afloat? Needless to say, without those..well that wont happen right? Looks like it was probably pretty worthless in the state it was in anyways.

Bilgecoat..special paint I imagine? Looks like a good idea. Any water protection back there would be good. Where did you buy that?

Yeah, just looked at them a little bit, and there was no way they were doing any good.

Bligekote is a paint designed to be chemical & stain resistant, so anything that does get in there should be easy to clean up.  I just picked it up at a local marine dealer.  He didn't have any on hand, but I'm finding out that we have a large distributor here in town and they'll let me pick up the stuff myself as long as I order through the dealer...so I was able to get it for the weekend.

I'm going to install some gunwale supports, and once the engine is in, I'll see where I can put foam that allows easy engine access.

[OleRed]

My 2 cents .. the flotation boxes back there, in my opinion, caused more grief for me than their designed security,  the foam they contain will Certainly absorb water, and most have.  The boxes being filled with foam do give some structural strength to the hull back there, but when they get soaked with water, they cause more stress to the hull.  I removed them from my boat, but I did re-inforce the cross structure with thick woven mat, then I filled those sections with foam, not quite as much as the boxes contained, but to make up for the differance, I injected foam under the entire floor, giving the hull more strength, flotation, and me a good feeling of security, it must be working on my boat, most know it has been givin some test of structural strength.

Here's a Link to the mod ... http://www.olered.com/RedsScimitar.html

I have to be honest, I don't understand Glastron's thinking...each of my flotation boxes had 4 rubber plug holes in the top, which allowed water to come in.  I'm assuming that's where they injected the foam after the boxes were glassed in...so I get it...but they were essentially built to fail.

I suppose if you're building to a 10 year usable life or something, they accomplished that goal.

Anyway, Red, here's what I did with mine...I filled all voids under the floor with pink foam...should water ever get in, there is drainage from bow to stern, but, I'm pretty good about keeping my boats dry.

Anyway, here's what I did, floor is 10x more solid then it ever was, and I've added more flotation as well.

The flat surface on the boxes were a convenient place to screw down the trim pump, battery, and other stuff,  all those holes are an opertunity to let water in those boxes, and you are right, as with all boat builders, there is a Line of concern about construction cost and U.S. Coast Gaurd and State reg's, and I do know that the production cost was a continual issue regarding the Carlson line

Managed to get Bronchitis for Labor Day weekend, and haven't worked this week yet.  Going in tomorrow finally.

A little progress...finished the Bilgekote...and glassed in supports for the rear portion on either side.  I don't want the bench seat to have to support it as its already cracked on one side.  If my plans work out, the rear will be a sundeck for my wife to lay out on, with the center section removable so that the original engine cover can be swapped in when I want it.

Just need to get the transom seal and bolt it back up so the engine can go in!

Looks great Doran!  Wish I had that garage to work in!!

As Mr. Steve Ackerman can attest...its pretty tight in there and with Bluebell in the 3rd stall now, I've become a gymnast just to get to my workbench.

But...it does hold both boats and my wife's car...so I've been making due.

[Hotwired]

Got room to build another garage off in the property somewhere?  I work for beer and boat rides!!

[AndyBean]

Here are the shots from my 18. No issues with support thus far. Doran you do great work. Great fiberglass work!!

[dorelse]

Hmm...thanks, but I think I mostly hack through it and get by...

I've noticed support issues on both CVZ's...the 19 at least has the fiberglassed finished area over the stern/bilge to add some stability.  The 18 (or at least mine) has one crack already and a lot more flex than I'd like to see.  It seems like everyone boarding the boat wants to step in one particular spot, and that takes a beating over time I think.

So..trying to strengthen both sides a bit so this doesn't happen on the other side:

[dorelse]

Andy - how are you keeping stuff from the side storage areas out of the engine?  My 1996 Glastron just had netting installed.  I was thinking about lightweight panels that I could slide in & remove when I needed engine access.  Are there more pictures of that area on your site?  TIA

[AndyBean]

There is plywood seperating it.  Let  me see if I can find a picture.
