1966 22-2 Diver Rebuild

[Capt Matt]

Rasied my floor 5 inches, my drains are out the sides right before the stern cabinet wall.
Its about the right hieght as the boat drains are above the waterline unless I have a few big guys stand on the back.
I made the drain holes 11/4inch so I can use standard plugs to plug them when carrying lots of weight.
Pay attention too that the water drains back, that the front deck is higher than the stern deck.
I also put a crown of 1/2inch in the center of the deck so the water runs to the sides then out

First, congrats on starting the rebuild.  Second, I want the Bertram next to it!

I know you asked Matt, but thought I would chime in: I raised my floor 1.5".  It was convenient because I kept a small amount of the original floor around the edge of the hull, and when I put the new floor in I glassed 3/4" block to the old floor, then the new floor was 3/4" about that.

Sorry I haven't been on in a few days, been pretty busy this past week. I don't have much picture worthy progress to show as a result... Got the floor out and the foam removed from the center two areas Maybe later tonight I'll get some pictures up along with some more commentary.

Matt, Thank you for the info and your advice about the angle and crown on the floor. I appreciate it a bunch. So, in your opinion would 3 inches be a mistake, as in not enough? I'm certain I'll have more questions as this goes along.

LilRichard, I have read through your thread about 20 times (no kidding), any advice or input you want to throw in is cool with me. Your boat came out beautiful man!

Thanks, and I wish it was a Bertram... It's actually a 1971 Uniflite 31. That one is my long term project which has now taken a backseat to the Aquasport. A great boat, an unbelievably seaworthy design but overkill for fishing the Great Lakes. The plan is to ship her down south somewhere once I get her done, a vacation home of sorts...

Sorry about the lack of updates, I took a position on a different shift at work and it has been quite the adjustment so far. I guess what I'm saying is I am freaking tired.

So anyway, I've removed a good amount of the foam so far. Lots of water, lots of weight, lots of garbage bags full of crap. No real surprises so far though, which is a good thing. I am on the fence about removing the liner, it is in pretty good shape from what I have seen so far, just a few blisters from being saturated. It is bonded very well to the hull and I am leaning toward just reinforcing it / sealing it when I recap the stringers.  





This is what leeched through overnight after pumping it out the day before...


Hopefully I can get the rest out this morning and get it dried out. I would also like to get the trailer on the floor today and start blasting/cleaning the inside. We'll see how far I get, the boss is bugging me about getting Christmas light up so...

[LilRichard]

I didn't have a liner in mine, so I don't have a real opinion... but if you keep it, how do you bond the floor to the hullsides?  Do you trim part of the liner back?  I wouldn't think that bonding the floor to the liner would provide as much strength as floor to hullsides... but like I said, didn't have the problem on mine.

Be very cognizant of the bonding issues with the stringers... mine were almost completely loose.  Hopefully you will be much better off.

[Callyb]

I may not be using the correct terminology to describe what I have. Instead of individual stringers glassed to the hull, it is one continuous mold. All of the stringers are one piece. I did the best I could to show what I mean in the picture below.



I am with you on making sure the bond is still there. Once i finish getting the foam out of the stringers I will be able to verify that whole situation.

Thanks.

Now....back to work. :|

my hull is pretty much the same way, i found the stringers where almost completely delaminated from the "bait well" forward, and spots of delaminaton midship forward. i went ahead and cut the entire center stringer out.

[LilRichard]

Ohhhh.... gotcha.  I didn't look super close at the photos, I thought you meant it had an inside liner - on the inside of the hullsides.  In one pic it looked like that because part was blue - thought that was the liner.

My stringers were the same as yours, they're one big piece dropped in and glued to the hull.

[Capt Matt]

Dont be afraid of going 3 inches plus when raising your deck, better the deck is too high than too low when done. I don't really see why anyone would save the old stringer system unless it was in really good shape. Seems like more work to defoam, re laminate and raise the old stringers than to build a new stringer system. By ripping out the old stringers it also allows you to re glass the inside of the hull before putting your new stringers in.
I had a factory liner in my boat and ripped it out as with a higher deck and different casting platform it needed more fabrication that it was worth.

I actually just got done having this same conversation with my wife.    

There is much wisdom in what you are saying and I am leaning towards that now. I got all of the foam out from between the stringers and a cursory look at what is going on when it was wet, but now that it is starting to dry out it doesn't give me a good feeling. It appears to have a little disbonding from the hull. So, I may just pull it and start from scratch. It indeed does look like more trouble than it's worth. I'm going to take a look at it again tomorrow and see what's going on. I have no intentions of doing this again!

Oh, Matt... I think we were watching you on youtube out on one of you charters catching monster tarpon. Do you have some on there?







Talk to ya later,

[Capt Matt]

I have had clients film there tarpon catches but don't know what happened to the footage.
What did you dicide on your stringers?

[Callyb]

Wow it has been a while...

Anyway, I have decided to replace the stringers. I am going to build new box stringers with the increased height built in. I haven't been particularly good at taking pics through the process, so not a bunch to show. But in any event, temps are supposed to be in the teens all week, so probable not going to have a lot of progress until it warms up a little.

I cut the stringers out in full length so I can make a mold for each so that I can hopefully drop them right in.


This is pre-chiseling/grinding. Also, the outboard stringers/stiffeners are removed.


I still have some cleaning up to do on the transom before it is ready to go back together.

Looking good  
You might be able to use those stringers as molds - cut the bottom flange off, cover in visquene and start laying your lam up.
BTW - how thick are those on the sidewalls and the top?

Actually, the logic in getting them out full length is so I can have a quick template so they new stringers should drop right in. Hopefully minimal trimming will be necessary when it comes time to drop the in.

They are 1/8" all around, but have a half round stiffener running on the inside on the top for additional support. As a side note the starboard stiffener was very inconsistent with the thickness, it varies from 1/8" to almost 5/16" in places. I guess the guy spraying was zoning out when he sprayed that side?

I'm planning on just reproducing the original design, but I always keep my eye out for a new way to skin a cat.

Talk to you later Rick.

[RickK]

Thanks, I didn't think that the ones I pulled out were very thick. Never thought to measure them though.  So maybe 3 layers of 17 or 1808 or both should bring it back to that thickness. So guys want 5 layers - that would be over 1/4".  What is your plan for thickness?
