First time poster here, hi everybody!

I have a 2000 13'sport that has been chainsawed in half, for the Newport (Ca) boat show. It payed for itself, getting full media coverage that night, footage of my boss putting around, drumming up interest in the show.

Since Schock wanted $4500 to rejoin the halves, and I'm both poor and cheap (plus I could get a demo for not much more than that), I have this project and no clue.

How would y'all go about it? Buncha' dowels and glass? I remember an article that mentioned using a torch. Was that a joke? How about just enough glass to hold the shape and then spraying the whole thing with rhinoliner. Structural bedliner has been done, but to this degree? If I just layer and layer glass, and wind up with enough strengh, but with a butt-ugly band-aid that protrudes 1/4" off the hull, would it destroy the ride?

I don't know if this has been discussed here (maybe to death), thanks for your patience with the newbie, and for any advice.

Welcome to the forum.
I'm a little confused so I will have to ask you a few questions.
1. How did it pay for itself? That's a fairly new boat!
(I assume you are related to the show's sponsors/producers/promoters).
2. Who is Schock? I'm form the other side of the country.
3. How did yall go about what? Rejoining the halves? I'll have to defer that question to any other members who may have done so, as I have no clue.
4. What were you thinking (read drinking and is your boss gonna pay for it to get put back together- we don't drink that much even in Louisiana at Mardi Gras)......(OK,... but I never bring my boat to Mardi Gras)

Sorry so sloppy... it's late... or something...

Schock is in Newport Beach, Ca., we got the boat from them. They quoted the repair price, maybe the quote was for their shop or the factory, I'm not sure.

My boss is the owner of Sea and Go Boating magazines, and we put on the Newport shows twice a year. He got a deal on the whaler, and Schock took back the outboard and trailer. Dammit.

The boat payed for itself because of promotional value, many folks saw footage on four L.A. channels that evening, both of the cutting and driving, and that gets folks out to the show. A number of folks mentioned it to me during the show, I believe it created a bigger buzz than any other of our stunts.

We always do some media stunt, rescue-dog, helicoptor rescue, water skiing dog, orangutan driving a boat (quite well!), the round boat (15' beam AND length), last show was a 33ft replica of the Arizona.

I'm definitely looking for repair ideas, I am almost ready to start on a cradle to get the pieces all lined up, but I'm long on effort and light on theory.

You might be able to reconnect the two halves, but I doubt you could restore the strength of the original structure.

Perhaps some stringers and a lot of expoxy might hold the two pieces together.

Ok so you got the boat for free and want to know how to put it back together? Whatever works but resale will be nothing. The dowl theory is the best, that is how they build transoms. I wonder if you made the boat a few inches shorter and did a tongue and groove repair like in furniture.

I honestly don't see how you could ever end up with a finished product strong enough to bet your life on. Here is an alternative.

Buy a used motor and mount it on the rear. Put together a nice brochure showing what you have. Build a decent shipping crate. Send the flyer to dealers all over the country and offer to rent it to them for their own boat shows for say $250/day plus shipping. Save up cash and buy yourself a new boat.

Instead of trying to put this boat back together, sell or trade it to a Whaler dealer to use in promotions and buy or receive in trade a 13 sport that is whole? In order to do this repair properly, the floor and deck would have to be removed along with all foam. This boat will never be right, please do not put it back together with the expectation of making money.

Not a bad idea guys. You can sell 1 half to 1 dealer and the other to another. Ya might make a couple G's. Renting it would be cool but shipping would cost a fortune.

Don't laugh. If you have a big enough room you could stand the halfs up and make shelves for it. I've seen it done with canoes cut in half.

Actually I'm seriously considering a 9' Whaler to make as a dinner table. Gotta wait 'til I move in in 2 months and don't have a table yet. It will make for a terrific conversation piece. A 11 x 4 sheet of shatter-proof glass would be the expensive part I suppose.

Now I've heard everything. You could put it together with the one that Pierce's relative claims to have behind the barn and start a chainsaw Whaler collection! (recent Forum Marketplace post).

Seriously, I think you have already made the decision to convert a boat into a promotional object, and it's best value is to use it that way in the future. Molded structural objects do not lend themselves to reconstruction after being cut in half. You would just have a crappy patched up boat, or a too-costly restoration.

You have got to be kidding about putting 2 halves back together, right ?

With dowels sticking out from the foam ?
Tongue and groove, mortise and tenon, biscuit joinery ? Even Norm Abram himself could not get this egg back together again.

Try to sell to a dealer as a promotional item and help prevent a future tragic boating accident.

W.D. Schock is a custom sailboat manufacturer in Newport Beach, California. Why would they be showcasing a Whaler 13's buoyancy?

Here is a link to Schock, and they are a vry large outfit:

Apart from the odd nature of who cut the Whaler, the suggestions for its use have been great.

This is not that hard of a repair to end up with something that is functional and will last well. To have it look like it was never cut might be hard, but not simply to repair it.

You don't need dowels, tongue/groove, or the like, since the strength comes mainly from the fiberglass skin. You would have to significantly cut into the fiberglass over a wide overlap - I'd speculate a foot or so on each side of the cut, but that's only a guess.

I've repaired whitewater canoes and kayaks that you would have thought should go into the garbage - really severe impact damage, not simply a smooth cut . If done well, the only really negative result after the repair is extra weight.

You would need to do a real structural repair, not simply using glass mat like the original layup. I would approach it using multiple layers of glass cloth and potentially a layer or two of aramid cloth.

Just thinking offhand, my inclination would be to first rejoin the bottom edge, gunwale to gunwale. At that point, I might be tempted to cut a piece out of the top deck along the joint, remove the foam, and do a similar patch (without fairing since its on the inside) on the inside of the seam. Then use some type of pour in place foam to fill that space and trim it off flush. Last, I'd either make a new piece to patch the inside or just re-glass the new stuff.

I didn't say it would be quick, but none of those steps are particularly difficult. I suspect you could do it fine without the inside patch also - it would be a lot less work.

I think that you should glass and repair the cut on each side of the hull. This way it will not be hurt by water in the foam. Then make a system of cleats to hold the bow and aft sections together. It will be more of a money maker because it will not only be a boat split in half but a boat the is whole that can be tranformed in a double hull and back to a single hull (a transformer whaler). You can leave the wife sunbathing on the beach on the bow and take the stern and go wake boarding.

Conceptually, I don't think it would be all that difficult to put it back together in a structurally sound way. Simplistically, I think you'd need to scrounge out the foam between the two hulls on each mating half for maybe 6" (maybe 12"?) each way from the cut then epoxy in wood to replace the foam. It might take some thought to decide just what species and type of wood, but it should be in my mind about the same thickness as the foam it is replacing. I'm thinking of epoxy-laminated plywood, and I don't guess it would have to be continuous; maybe it could be pieces 6" or 8" wide (and however long it needed to be to get from the solid foam on one piece to solid foam on the other) and each piece would alternate with a void of similar width. The voids could be filled with expanding foam.

The structural theory on a Whaler is the two skins acting like the upper and lower flanges of a beam with the foam acting as the web, so as long as there was something filling the void between the two hulls and well adhered to each, (like the laminated plywood epoxied in place), the project would then be reduced to simple structural repairs to the fiberglass inside and out, following Whaler, West System or other guidelines for cutting back and beveling the existing glass and then laying back overlapping layers of fabric and epoxy (or that stuff that Tom Clark uses :-). Then gelcoat and you're done.

As I said, conceptually it is easy; operationally it would be quite a project. Doable though.

Take the front half and glass in a transom, BW dinghy's are getting scarce. I would buy it for a planterbox but I am already on my second wife. Or you could stay up real late and look for that infommercial with that amazing superglue, one drop lifts a bulldozer so I guess gluing a little tub back together would be a cinch. Seriously I never thought anyone who took a chainsaw to a Whaler was thinking about fixing it later. WD Schock has been around along time, believe I have seen Schock 23's in wood.

You now make a custom trailer for it, and haul it around from show to show as a whaler demo. At the Miami show, they had the rear half with the engine puttering around the marina carrying would-be purchasers and skeptics. I guess you didn't realize Whaler had their own boat like this, doing traveling shows...

This discussion brings to mind an aluminum skiff I saw last fall in the Denver area. Someone had taken a 12 or 14 ft skiff and cut it apart in the middle. They then fitted a "transom" to each half and hinged these "transoms" together at the top with an oversized piano hinge. This allowed the bow to be folded back over stern at the middle, making a much more compact trailering arrangement. An assembly of eyes on one half and hooks with screw bases on the other mounted on the outside of the gunwale above the waterline were used to hold it together. It was powered by a small outboard.

You may be able to assemble the first ever foldable whaler if you use this approach.

Don't repair it. It could wind up in the general market place someday and get sold to some unsuspecting soul who could lose their life if it falls apart on them out in the water.

If you go to the whaler site, you'll see a nice setup to trailer such a boat. Someone is already taking t hiers on tour...looks pretty neat but I'd really hate m yself in the morning if I woke up and saw my whaler in two pieces!

Check it out...

Good luck...

Wow, you guys are great. Lots of good ideas.

Resale is not an issue, this is for my own putting around, and if it doesn't work out I think it would all fit in one dumpster. As for concern about a future owner, it will be real obvious what it is, especially after I paint a bunch of band aids across the seam and call it "Rejoined" or some other silly name. Caveat emptor.

Lots of good ideas for a promo boat, but I don't want to do the legwork, and I spend more than enough time with boat salesman already.

As far as safety goes, what's the worst that could happen? I guess if it came apart at high speed that could get ugly, but if the bow simply breaks off and floats away, I will simply drive it back. Maybe towing the bow. It's how I got it on a trailer. It had a four-stroke 50hp on it, and I weigh 230, and it still was almost a dry ride. Good thing for power trim.

I do have some pics of the boat, driving in the harbor and on the trailer, but I need to figure out how and where to post them. A yahoo group, perhaps. I saw a few folks snapping pics on I-15 at 75mph, wish I had copies of those.

I do like ideas for furniture, but it is not deep enough for a hottub or fish pond, and I don't really have the space. See dumpster.

I have a feeling that Norm Abrams wants nothing to do with this project, but I would like to raid his woodpile and borrow just a few of those tools...

Kingfish and russellbailey have some great tips, I hadn't considered removing large amounts of foam to get at the inside seam, but I like it. I just recently saw that mix-n-pour foam product on Monster Garage, the stuff looks easy to work with. What do you guys think about many, many layers of glass inside for strength, but just a couple on the outside to keep it smooth?

Unfortunately, the bow piece is too small to be a dinghy on its own, but I could have the flattest nosed 8 footer, ever. I suspect this might effect the handling performance. Severely. Extremely. Maybe fatally.

I just read a couple days ago about that promo tour with a halved BW, thanks for the link to their trailer. Supposedly, ours was the first to be halved since the factory did that one in the 50s, but I heard that from our media guy, who I believe like a boat salesman.
I have never heard of one being rejoined.

A folding boat, hummmm...

Mount it on a wall, for the boat-through-the-wall-effect?

I am half serious about spraying the rejoined pieces with bedliner, I can get a deal on that part, American Bedliner might do it just for the exposure. The stuff has a burst rating of 250lbs of TNT. Not a typo. After 9/11, the Pentagon rebuild used the stuff extensively, it is close to bombproof.
It comes in a variety of colors and textures, including smooth as glass. Before you scoff, let me tell y'all about a trash collection pontoon boat, owned by the city of Long Beach, Ca. The tooner was put into service without any anodes, and electrolysis (sp?) ate up the toons in a year. The aluminum was paperthin and porous. Drained, dried, and sprayed with bedliner, that thing is still working the harbor after five years. They added two more sprayed toons, I suspect the stuff is not light, and they needed the bouyancy.

Structural bedliner? Sounds kinda' silly out loud...

One last thing, any suggestions for names?

Rejoined, Rejoiner, Repaired, Half Assed...

T_bro is right. Schock is the BW dealer in Newport Beach. Their website had nothing on their powerboat business. I couldn't find anything (on the web) about Sea and Go Boating magazines.

Don: Is this a relatively new magazine? Is it published for the local area only? I am interested because I grew up in southern California and wanted to take a look at the content. Is there a website for the mag under a different name?

OK my 02,
I don't think this would be a hard project at all. Start by outlining a profile of the cut on heavy stock. Sit half of the boat upright on the stock and trace boattom contour, then draw a line from the port to starboard gunnel. Cut this out it will be the pattern for a new bulkhead you will be installing. Then transfer the pattern to whalerboard or other marine material, could use marine plywood.
When you have cut the bulkhead align it with one half of the hull, liberally coat the surfaces with adhesive and screw or dowel the bulkhead to half the boat. Let this cure then attach the second half of the hull. You should have something resembling a 13 with a center bulkhead. Now using whalerboard again cut a piece to fit from gunnel to gunnel AKA a seat! Screw this to the gunnels and the top of the bulkhead with stainless fasteners bedded in adhesive. A bit of gel coat should finish the bottom, or you could rout the bottom of the repair some (scarf?)fill with glass and fair the bottom. Me thinks you would have as strong if not stronger craft than left the factory.
I have seen many high performance aircraft built from parts retrieved from crashed aircraft. And a lot of cars are rebuilt after a major accident.
Hey, keep us posted.

With all of the discussion of waterlogged foam recently, I've just got to ask how the large exposed areas of foam behaved? Lots of water soaked up, or just damp around the edges? If the rear half of this hull didn't absorb lots of water, does that suggest that there is more to the foam absorbtion issue such as age breakdown? I guess you can just stand this hull up on the cut end and it will drain out pretty fast, if needed ;-)

Excellent point on the foam, msullivan.

This is what its been through:

Started out with 0 hours, never splashed.

Marked out a line, and cut it straight and neat, for a chainsaw. Huge cloud of glass and foam dust. Very nasty.

Launched it, drove it, let it sit in the water, with exposed foam in the saltwater, for five days, (during the show) and drove it to the ramp.

Then it sat on a driveway, tilted to drain, for a two years. The wet spots formed under the draining edge dried up after a week or so. The rainfall during that time was very little, two years of heavy drought in the L.A. area. If I'd known it was going to become my nightmare, I would have stored it better. 20/20 hindsight.

Since then it has been covered in my carport and hasn't been damp since last fall.

Sunlight damage to the exposed foam is obvious.

How can I tell the extent of water damage? Since I plan to remove at least six inches of foam from the cut edges, I will have a better look at the condition of the foam then.

Schock boats:

They've been around for a long time -- they were the dealer that sold my Revenge new to the 'Fishin' Judge' back in the late 80s, and they were the only Whaler dealer at the LA boat show.

As to this thread -- I have my doubts, but I see so much weird stuff in my professional life that THIS wouldn't surprise me at all.

I say donate it to a vocational or technical school and let them go wild on it as a project.

It will be a lot of work, but it is very doable. I was going to post how I thought it could go back together, but it would read just like what “russellbailey” posted. The short of it is to scrape out foam on both sides, re glass the keel and gunwales and sole. Then pour two part foam into the void in the middle. The re-glassing parts will be need to be backed thicker than the original so much preparation must be done, and glassing must be built up on the inside with woven roving with mat on each side and mat on the outside using polyester resin. If you can get your hands on Kevlar roving for the inside you will be set for strength for such a large repair. Re-glassing only on the outside will work but will never be as strong as the original. “I would love to do a project like this.” Just my thoughts, Archie

The skin can be repaired, but the "I-beam" construction will be more difficult. By this I mean it will be hard to get the top and bottom skin to bond to the foam without voids, which is critical the keep the joint from flexing. I have seen broken surfboards that have been glassed back together, and they usually break again since the stringer acts as the web in the beam construction. In Whalers, it is the foam itself that separates the flanges. Unfortunately, in order to prevent the boat from a hinge failure on the repaired joint, stringers much longer than the repaired area will need to be fashioned. A heavy full length keel is another alternative, but it will change the performance of the boat.
