68 Chrysler hull ? Deck questions

[timewarp]

I've looked at chryslercrew site at the brochures , and could not find the hull design unless someone had modified alot on it already . Is there another way to find out ?

I just got this boat and the plan is to use it as a fishing boat for a year maybe two . I planned on changing the wiring out to new wires and repaint and so on . The boat for the most part is solid . The transom and front deck are very solid . The floor/deck from the transom to about 12 inches past the livewells is also solid. i decided to take a small peak at a bad spot and cut a small spot out to inspect. ( pic 1 )The wood appears to be 3/8 inch thick .
All i could find for support is the foam seen in the hole running down the center of the hull . I inserted a tape into the hole and from front to back of boat there is no support . I searched thru posts to try to find some pictures to show the best way to remove the old wood as it seems (like in picture 2 ) the deck sits ontop of the hull .
Could someone point me in the right direction ? I've thought about just putting new wood over whats there now , and iam sure i could use the boat for a couple years but want to see options .

pic 2 appears slightly raised

Re: 68 Chrysler hull ? Deck questions

Thw transom looks to be shot, I'm curious how you decided it was solid.
it could be ok but it don't look good from here.
The clues are the metal reinforcement plate and the whale tail, both indicate flexing or compression in the transom.
Forget banging on the transom, you may as well bang on a drum for all it will tell you.
Drill into it and check the drill chips near the drain.

As for subdeck, if you're gonna do it just go at it and cut it all out, then you can see how they built it and replace with new.

I have a chrysler center console 1974 20 foot.
My signature shows the deck removed, the deck sat on foam with a couple of stringers on the sides of the gas tank.
I put the original glass deck back in again after replacing stringers and transom.
Chrysler crew just want to sell stuff, i have no time for them.

Yours might be a commander or commando.
Did you look in the chrysler section here?

Re: 68 Chrysler hull ? Deck questions

Thanks jonesg ,
What i did was drill 4 holes on inside of transom on left and right side , 2 at the top and 2 at the bottom. I went about 5 inches above the deck and 5 inches below the top of transom . I drilled about 1 inch into it, and inserted qtips and it was dry . The wood doesn't appear to be a dark color , but not light colored like new wood . I took a small screwdriver tip and it didn't chip away nor was it brittle .

The transom top is raised where the motor mounts , i thought maybe thats why it was there .

On the deck/floor iam not sure how it meets the actual hull . Thats what i was looking for in pictures. Most pictures i see it doesn't seem to seat on the hull , the deck is slightly above hull . Iam thinking cut it close to that area and remove a section , then do i smaller area to see just how it seats .
I'll check out the Chrysler section also

Re: 68 Chrysler hull ? Deck questions

It looks funky but shakira says the chips don't lie.

To see how the deck seats in the hull, cut it off.

Re: 68 Chrysler hull ? Deck questions

Started taking it out , I noticed the wood was not coated with anything and also noticed the edge was cut at a angle ( pic 1 ). I think for the removal the hardest part will be grinding where the angle was so the new wood will sit flat and i can lay the new glass on it .( pic 2)
The foam stinks bad ... and the stringer appears it was install not covered completely either. (pic3) In the 4th pic you can see where the foam went to . Iam debating of redoing the same with the foam or should i make braces ( going left to right )and glass them to the floor for support ?

Pic 1 -angle cut

pic 2 need to grind this

pic 3 not covered well at all

pic 4 you can see the distance the foam came out to.

From my other thread , i decided to move forward and if anything do some hands on repairs to work a new floor . My boat has only one stinger and had foam against the stringer that came out about 6 to 7 inches. The wood i removed was 3/8 , which didn't seem thick to me . I wanted to add some ribbing for deck support and planned to just use foam inbetween the ribs .
I went to a local marine suplly store to get some prices and start picking up a few things . A salesperson asked what i was trying to do , so i started to explain . He said i should just install foam back and 3/8 decking would be fine , just bring the foam so the deck also sits on it . He then said if i really want to add ribbing , Don't glass the ribs to the hull itself , use foam under the wood where it touchs the hull then glass.

Now iam lost on should i just do the foam or ribbing . Looking thru posts on here i see all the ribs glassed down , is that what i need to do ?

Re: Went to get some supplies , now iam lost again .

ok.....first off......we need a link to your other thread or piuctures of your stringer set up.

the information given you may not have been good......some boats require foam as a structural component, so blocks just wont do.

as far as butting foam under the stringers.....that is called bedding the stringers...you want to keep the stringer off t5he hull, as this will create a hard joint, and possibly crack.
there are many ways to bed a stringer....from pl 9000 to a resin substance we call peanut butter. to just shiming the stringer.

as far as not glassing the stringer to the hull......WTF ???? :facepalm:

at this time i cant really picture a single stringer system.....so we need more info you your boat.
the general rule of thumb is to replace what was there.....but if you want to add cross frames...its your boat....you can do what ever you want to it

if you choose to cross frame your boat, depending on the size....2 or 3 cross frames is lots....one 3 feet forward of the transom......one center...and one under the windsheild area...

or....every 4 feet from the transom......(this will help you attach the plywood decking)
after you have your cross frames GLASSED IN TO THE HULL AS WELL AS THE STRINGERS.....you can foam the area between the stringer and the outer hull.
this is uasually 2 part pour in foam for structural purposes....or anything you want if its just for flaotation.

Merged the threads. Try to keep one restoration in one thread so people do not have to hunt around as a result of statements such as "From my other thread ". I am sure you understand that people DO NOT want to research your other thread so we keep them together!!

Thanks.

Are you sure thats Chrysler? http://www.allpar.com/old/boats-1969.php you can check that website it doesn't look like the commando 151 it might be the dart though and if so it's a 1969. look at the website you can decide what you think it is. i definitely don't think it's the commando.

Re: Went to get some supplies , now iam lost again .

thanks bob

this single stringer is because of the tri hull....some of those had 3 stringers.....

look in the compleated projects forum for redfurys project. its another tri hull.
also johnnys pics of work so far.....thats a glasstron tri.


as you can see...the stringer is glassed to the hull

Re: Went to get some supplies , now iam lost again .

Re: Went to get some supplies , now iam lost again .

ya my tri hull only has one main stringer and thats it. it has little 2x4 on the edge for support and thats it.

Re: Went to get some supplies , now iam lost again .

Thank you
I looked at the brochures and thought maybe it was a dart , but i don't know what alls been changed on this boat . Title just say 68 Chrysler 15 foot .
Also , thanks for the answer opps!, i thought maybe i missed something when i was reading about putting in ribbing /support . As for the 3/8 thickness that was there , i have no idea if that was was came factory , would 1/2 add considerable more strength to use it instead ?

Off to read more posts .

Re: Went to get some supplies , now iam lost again .

I have a few questions , but my terminology is not greatplease bare with me ...

1) I have removed all the foam and the floor now except the very edges where its angled because the edge of the wood was cut at an angle . I have not removed the stringer yet . With the floor removed should there be any flex to the hull ? ( like if i put my knee on it , when removing the edge. )

2) Should i clean the hull with acetone and another layer of mat since its open now and what would be best mat to use there ?

3) I debated sistering the stringer since i only plan on using the boat for a year or two at most , house will be paid of in 1 1/2 years and iam getting a new boat !! I read that its not a good ideal most of the time so i guess i won't do it . I read opps thread on extending your hull like mentioned above and looked at the stringer install. I see where you used the PL and went around the stringers after . I still not sure on the part before that thou . Do i remove mine and clean and dry the groove out and take say something 1/4 inch thick and try to keep the PL that thickness ? If so how long do i let it sit before placing the stringer on it , and finish with PL then glass it in ?

4) Because i only have one stringer i want to add ribs or frame it might be called ( going left to right on boat ) do i do them the same way and put PL under it too ?

5) Do i need to make a hole at the bottom of the rib/frame for the water to drain to back of boat if water does get in somewhere ?

Re: Went to get some supplies , now iam lost again .

well i'll say from my experince and seeing that we have the same one beam. the hull can flex mine does that and the boat is still fine don't worry about that. but what i did for the deck was since i got the middle beam too i put a half inch hole or a little less into the beam in the back for water in the bilge to get to both sides of the beam. then under the deck instead of putting wood i am putting foam that you would use on a dock the blue stuff i got it for free so. i put pieces cut to fit in there with space around them to let water get through. and that what i did. you could use foam instead of the ribs your talking about. that what i did and the what other people have done that iv'e seen. since your only going to have it for a year or two you can do it like that. i only plan on having my boat for a year or two also so.

#1 yes the hull will flex

#2 don't think you'll have to remat the hull it will add weight

#3 I would remove the entire stringer...grind the hull clean 6" either side of the stringer clean with acetone,bed stringer in PL no need to wait,filet the PL on the sides of stringer....let cure (check the drying time on tube) Then tab stringer in with 1.5 oz CSM then 2 layers of 1708 biax.

#4 Those would be your bulk heads you set them like the stringer

#5 Yes make holes through your bulks I use 1" pvc pipe nipples about an inch long and calk with 3M 5200

Last thing is I don't see in your pics an open bilge area in the aft of the boat.... where is your drain plug @ your deck height?

Re: Went to get some supplies , now iam lost again .

Thank you rickryder , I haven't got to the very rear yet . I went past the stringer to see how it looked . I got to get the livewells cut out also and build cradles before removing the stringer from what i have read. I see alot of people do just leave it on the trailer without cradles ?

I can see the hole going into the bilge area seems a little high ( it was holding alittle water when i cut the deck out past the end of the stringer - pic 1 --

Pictures 2 and 3 are inside bilge area and drain hole at back of boat.

MEtal plates on the transom spell rotted transoms.

Re: Went to get some supplies , now iam lost again .

Re: Went to get some supplies , now iam lost again .

jonesy is correct....you are going to do a transom here.

to leave the boat on the trailer you need a bunk trailer that is correct for the boat....it must support the hull with out any flex, if you have rollers.....make cradles
