Some clippings from an old Yamaha sailboat promotional brochure.

Dev & I replaced all of the wiring aboard our Y33 last winter, and I've got to say... the 'integral electrical conduits' they're raving about *sounds* great, but in reality we couldn't use ANY of them to pass the new wiring XD...

Not sure any of the builders expected the boat to live to be 42 years old.

A clipping of a promotional brochure for a Yamaha 33 sailboat, showing technical drawings of how the electricals are routed via integral conduits in the hull. The text reads:
"The key to every Yamaha racer/cruiser is the integral grid-and-box structure that forms the backbone of the boat. This backbone combined with the hull skin and stringers, gives the boat tremendous rigidity. The grid-and-bo structure is laid up on a mold like the one pictured here, and it provides integral conduits for electrical, plumbing, and exchaust systems, as well as solid, three-dimensional anchor points for equipment. This kind of engineering allows us to build a very strong boat, with a relatively light hull, so performance is increased along with safety.
A similar solution is used in the deck of our bots. Stress areas are cored in marine plywood, and the entire deck is mated to a light weight grid structure. This solution allows us to integrate electrical condits with modular circuitry."

@rek were they obstructed somehow?

@hobbsc Yes. Many of them are still in the walls, we couldn't get existing wiring out.

Love the drawings in the brochure, this one's especially neat.

an illustration of a yamaha sailboat at rest, on calm waters, the one next to it shows the boat under sail with the pressure in the rig.

A snapshot of a Yamaha 33 sailboat promotional brochure, showing an illustration of a sailor in foul-weather fear climbing the companionway stairs. Each stair is terminated by a rubber/metallic border, for better foot grip.
"Toe space on the companionway of the 33 is another little feature that sets our boats apart. By making the stair treads narrower, we can give you more usable cabin space. By tooling the companionway mold with indentations for toes and heels we make the ladder safer too."

@rek are there any features of the boat that you've discovered recently that you didn't know about? sometimes on my older stuff, i'll completely overlook a feature until i find an old manual or something.

@hobbsc Oh yea absolutely~ mostly for things we haven't taken apart yet (deck and hull joint for instance).

@rek Comme prof de "Statique et résistance des matériaux", ces flèches m'irritent particulièrement.😐 Belle aquarelle, par contre (ou du pastel sec?)

@rek tight conducts to pass wires sound great on paper.

They should have phrased it like "Our cost-cutting duct taping of house-grade wire in tight conduits will ensure that you have to cut othe walls open when repairs need to be made"

@neauoire @rek I'm being whimsical and naive here, but humor me, what if all the wiring for a ship like Pino was zip-tied to a narrow clothesline on a pulley inside the wall?

So you could crank it clockwise and counterclockwise, and then when it's all done you'd crank it to the proper position and plug stuff in 🔌

@rezmason @rek we can't have wires hanging like this, stuff will fall on them and rip them out, it's a sailing ship, not a sci-fi movie set ;)

@neauoire @rek I thought Pino was a Space Battleship Yamaha 😜

@rek What was the problem with re-using the conduits?

Apart from anything else, I'd think modern wiring ought to lighter than old stuff with NEMA2000, LED lights, etc.

@edavies Older wiring was stuck in them, couldn't get em out, they're jammed in.

@edavies funny enough, we removed a whole wall today and got two thick wire braids out XD... (doing that is very destructive tho, shouldn't have to take a boat apart to remove wires hehe)
