87 Stringer blue print

And much thanks to SKIBUM for posting his pictures of his rebuild. That's where I got my sketch from.

I have either dimensions, or access to all these dimensions for an 82. However, if your drawings are somewhat accurate, it appears to me that they tweaked the configuration a bit by 87. BKH

Well, I have my floor wide open right now with the newly installed stringers exposed. I also have tracings of the stringers before I fiberglassed them back into the boat. I cannot remember if I traces the secondaries, or only the primaries. I know I have tracings of the primaries, and I had a very, very good fit for my primaries.

Thanks any how, In 84 they widened the mains for the engine cradle so anything after that is a hair wider. They also tweaked the height of the floors in the 2001 models so I think I need to be +/- a year to be accurate enough.

Yes, should be able to do it this weekend. Send me an email so we can get some info. Bhall@Spigit.com.

Brian, I'm unable to e-mail you. Mine is rogeresullivan@yahoo.com

Drop me an e-mail and I'll contact you.

Thanks.

I have an 83 and it has the aluminum engine frame.

Im sure youre aware that CC started installing cradles in 1980? Stringer spacing on all non-cradled boats Ive put a tape measure on is right around 21" (inside to inside). The 89+ boats are significantly wider (~26.5") to account for the tabbed cradle. It would be interesting to know the spacing for all non-tabbed cradle versions. I've been in contact with Art Cozier of Correct Craft. Here's a snipit of the e-mail he sent me. "I wasn't able to spend enough time with the forums to figure out just who was saying what. I saw some info on there that just isn't right. To the best of my knowledge, the deck length of the 2001 series SN never changed. There was lots of tweaking from year-to-year with floorboard height, but the stringer shape on the bottom remained the same from 1982 through 1989 except when we set them wider apart to accomodate the aluminum engine frame which I think started in 1984."

Art is a great resource for all things Correct Craft but Im not sure that info is correct, as the cradles definitely started in 1980 (see #11), at least on the Ski Nautique. The BFN was a few years later though- perhaps thats what he is thinking about?

Regardless, I would be surprised if the stringer width was different on the 1980-1988 cradled boats than the previous non-cradled boats, as the mounts still secured directly over the stringers- though they were through bolted to the cradle instead of lagged into the wood. Perhaps some pre-89 2001 owners could throw a tape measure between their stringers? The stringers definitely got wider in '89 with the "tabbed" cradle, where the mounts through bolt to tabs welded inward of the stringers. This allowed for a much simpler stringer design- there are no notches on the top side to accomodate through bolts, mount heights, etc.

As far as the deck goes, Im not sure Im following what he's saying. While the overall length of the deck didnt change (the hull remains the same length on all 2001's), its pretty obvious to me that the length of the closed bow shrunk in 1987. The 87-89 boats have much more room between the motorbox and dash- you can easily walk between the box and driver's seat, which was more of a challenge in the 1982-1986 boats.

The decks on the 82-86 and 87-89 are indeed totally different. The 2 most notable differences are the bow area and the notches on the sides for the step/grab rails.

I dont think anyone was implying that the different deck would have any effect on the stringer shape. Thats a function of the hull shape, which didnt change from 82-89. I cant say Ive noticed a difference in floor height between the 82-86 and 87-89 boats that Ive been in, but that doesnt mean it doesnt exist. The delux interior cushions (which I presume were the same from 84 onward) look like they line up with the deck lines pretty closely though- so I doubt the changes were huge.

I stumbled accross this:
Bills Boat Works

Tim made a reference to an old thread about props and one of the guys, SkiBum, had this in his signature. Not sure how active he is on the site lately, but he has a pretty well documented 2001 rebuild. Not sure if he includes actual specs though.

The "individual" from Bills Boat works is "SkiBum" on here, aka Bill. He pops in less frequently now that he owns a MC, but his stringer thread was really the first of its kind on these forums... I think he inspired a lot of people to tear into their boats!

Trying to find exact stringer dimensions before undertaking your own project is really not necessary. The only real help it will be is to buy the correct amount (and properly sized) pieces of wood. The shaping to the hull will need to be done on a case by case basis anyways, as each boat will vary somewhat, and the amount of glass left behind from the original stringers will vary boat to boat. The only real critical thing is to get things right where the engine will sit- the height off the hull and distance from the shaft log are the main things to concern yourself with. Take a bunch of measurements before the boat is gutted and you'll be fine.

This should get you started. This was a sketch of the secondaries I found when building mine. My secondaries were already gone when I bought the boat so I used this rough sketch to build mine and they came out pretty nice.

If I remember correctly, someone had already done a stringer job on his boat, which was anything but original. It has failed and he is now redoing the stringer job. I think he wants to get it back to something close. ICBW. Too many stringer repair jobs to keep them straight. BKH

This is from your 82? Thanks

Does anyone have any pictures of the floor area up front after foam is in, but before the ply is put down?
