    Express 34 hits submerged object, now what?

    So, I was wrong. Almost certainly not Klegecell based on the info posted so far. A bit surprised they would have used cored construction in that part of the hull. All of my boats have been light weights of cored construction with 18" - 24" of solid glass along the centreline from bow to stern. Yes tapered core where the two meet up.

    Yes, the PS article says balsa. But as Zoomie pointed out, the PS article says that is the Olson 34 that is balsa. The Express 37 link posted by AlexW mentions PVC and balsa and apparently the 34 is similarly built. Although it doesn't specifically say the 37 uses PVC, I cannot reason why they would mention the merits ofPVC unless it was used. Agreed Klegecell is more of a salmon colour or reddish brown - but I have cut many wet pieces of klegecell out of a deck. When sliced open they are a dark pink or red, but the dried out outer surface is much lighter in colour almost a whitish tint on the surface. Actually, it looks like there are bits of foam in the bilge in the second photo - and those look pretty much identical in colour to the Klegecell core I pulled out of my last boat.

    Yes, they were discussing 3 different boats in the article and I guess I lost track. Nevertheless, still looks like Klegecell to me.

    The article says balsa was used in Hull #1. Olson Yachts ran into financial difficulties and the tooling was picked up by Ericson who claim solid glass. From looking at the photo, and given the pinkish colour and era of construction, I am thinking Klegecell. Also, in the second photo there looks like there is some pink foam fragments in the bilge area between the floors. But it would be an unusual place to put foam.

    Traveler strength over span

    The chart indicates for a mid-boom arrangement with a 30" span, you can go up to about 260 sq ft with the Harken High Beam track (1 5/8" high). Remember this is unsupported span, so no need for a backer. Backer is only required if you want to use the Low Beam track and the span is otherwise unsupported. As your track is only 1" in height, you can consider yours to be similar to the low beam track. That is, it will require backing. Remember - beam height or depth is the prime driver of stiffness for a given material.

    Traveler strength over span

    I had a fractional 27 footer - slightly bigger than a J/24 with the traveller spanning the cockpit tub. IIRC, it had a track with about a 4 " deep teak backer. The backer was radiused on the bottom side - about 3" deep at the ends I believe there were about 1/4" thick metal L brackets with about 4" legs at either end of the backer. I can't exactly how it all went together, but I believe the brackets were double bolted to the cockpit walls - creating fixed end rigidity. I might have a photo or two lying around at home and I will see if I can dig them up in the next day or two.

    This is going a bit far

    The West Coast of Van Isle would get hit by a tsunami when a mega thrust earthquake happens off the coast of the island - but the likelihood of a tsunami of any significance reaching Genoa Bay is almost nil.

    I was only guessing about George O'Brien since my recollection is from nearly 50 years ago. I never met the man but I assumed at the time he had to be a wealthy older man - I hadn't really considered that he may have acquired his wealth at a fairly young age.

    Sad Sack 12?

    Well, she was listed at 1.8M Euros and has sold. Beautiful looking boat from the resto photos. it looks like they used the original frames for the most part. Maybe even a bit of planking? IDK. In boats like these, I would think provenance may be worth a lot more than the value of the remaining materials.

    This one has nothing on the 12 Metre Jenetta which was recently retrieved from the bottom of Pitt Lake BC and sent to Germany for restoration. the last photo was taken before she went to the bottom obviously - but I doubt it is a very old photo.

    Are you certain it is the same George O'Brien and not a relative (possibly grandson?). That would indeed be awesome if it is. Endless Summer was ex-Dame Pattie. Now if Dame Pattie had been used instead of the Cooper, that would have been something. Except she has been cruisified and is known as Dame Pattie again. There are some photos of her casually racing with "Geronomo" (America II) off Ladysmith back in 2006 with a photo captioned with a Tom O'Brien (possibly a son?) at the helm of the committee boat who looks somewhat elderly himself. She was recently sold and went to Europe THE George O'Brien had a property off Paddy's Milestone in Maple Bay. He kept Endless Summer there with a whaling ship or perhaps an old coast guard vessel as a breakwater.

    Valiant butt surgery

    That may be true, but metre boats went down the wrong path in the late 60's (minimize wetted surface and increase displacement to increase waterline). Below is Toogooloowoo V, followed by a B&W of Valiant being splashed (literally) - you can readily see the resemblance in the stern and keel to Valiant. http://www.6mrnorthamerica.com/toogie5.html it should be noted Toogie V lost to ex-Toogie IV in the 1970 American Australian Challenge And Toogie IV had lost to the 30 year old Goose (US81) in the same challenge the prior year. There is mention in the link above of a loophole in the rule with regards to measured waterline which they were trying to exploit with Toogie V, which was later closed. I wonder what it was and if it applied to both the 6mR and 12mR rule. Rudder in the 1973 Seattle photo most likely changed by Mull from the original S&S design.

    Valiant butt surgery

    There were a couple of other penalties as well. One if measured beam was less than base and another if displacement was less than a calculated amount based on LWL. IIRC, the draft penalty was much higher than simply the difference. It may have been 4x the difference while for beam it may have been 8x, If the draft penalty was only 1x the difference, that would not be really punitive - I think it would have been a great incentive to give it a go.

    Epoxy/aluminum long term bonding

    Here's an interesting product, which I believe was developed by Boeing as BoeGel 130 , manufactured by 3M and available here: https://www.skygeek.com/ac-tech-ac-130-surface-treatment-2-part-kit.html#

    Epoxy/aluminum long term bonding

    It's related - but it's not the reason. Building me a FrankenDash - it's a popular pastime in PNW (how's that for an alliteration) Lots of alterations planned - too many to list here.
