fiberglass crestliner stringers

[bman1bpm]

So on removal of the floor of my boat, It does not seem to have stringers like most other boats have. It looks like it has half round tubes that run the length of the boat. In order to support the floor there are pieces of plywood wood that go width wise. Has anybody seen a boat like this?

My chrysler has a half pipe down the keel but stringers on either side of the tank compartment, it looks like they layed it up on pvc pipe then glass it in place afterward, because there is no pipe inside the glasswork.

I wish they had installed half pipes under the foam.:redface:

yeah thats exactly how mine is, it looks like PVC pipe cut in half then glassed over, but there is no pipe inside the glass.
There are some very short stringers in the back compartment where the fuel tank used to be.

I'll try and get some pictures up in a couple weeks, for now heres a small drawing I made.

Re: fiberglass crestliner stringers

well the floor was all stock when I pulled it up, and the foam was definatly original so I don't think anyone has been in there. I'll get some pictures up soon

Re: fiberglass crestliner stringers

Re: fiberglass crestliner stringers

Well all the foam was soaked so it had rotted the wooden floor support so I had repaired them. I did the repair work a year and a half ago. Planning to pick up the floor again and see how its holding up. Floor is still bare plywood, haven't gotten around to covering it with anything yet.

Re: fiberglass crestliner stringers

ok heres a long awaited photo. I was wrong about the back ones being wood. there is just a center wood piece in the back on top of the tube stringer to support the wood in the blige area.
If I remember correctly the tubes run the full length of the hull, haven't pulled up the floor again yet.

Sometimes they used a mold and made half round stringers to put in place, but it was also common to use the cardboard tubes the glass is wrapped around and cut it in half, then glass over it.

Easy, cheap and no rot.

Re: fiberglass crestliner stringers

yeah no rot is good, they seem to be deteriorationg though. You can see the one on the far left has a hole in it. I'm thinking of covering them with either 1708 or a few layers of mat to beef them back up again.

What's the model year on your Crestliner?

Re: fiberglass crestliner stringers

ok heres a better picture of the full length. Some of the tubes are solid as a rock, others seem like the factory got cheap on the resin in the first place. What would be the best repair method? Also how should I go about tabbing the floor supports back in? I've cut new ones already.

any advice?

Re: fiberglass crestliner stringers

The bad spots you found can be fixed by grinding down the surface a little and then adding a some glass over the top. Don't worry too much about it because it held up this long with no apparent issues.

The wood should be covered completely with glass for it hold up long term and just use about the same amount of glass as was used in the first place to tab them in place.
