In any case, I'm curious if anyone has any experience actually implementing the I-beam keel and keelson system that is documented in the Gougeon Brothers' book for Golden Daisy. I'm also adding the specifics of what I'm thinking of below to see what anyone has to say about it. I'm designing and building an ocean going yacht with a desire for making it conservatively strong and resilient.
Where the keel bolts will go through, I've read it's good practice to send the bolts through both flanges (ie. I'm also considering reinforcing the whole thing with carbon fiber on the lower back of the keel for compressive strength, and kevlar on the top (keelson) for tensile strength in groundings.
Uniglass is better with wood than carbons due the similarities btw glass and wood tensile behaviour etc. Location: maine IT seems to me that an I beam would be totally inappropriate when a solid beam would be heavier to such a small degree that you could literall carry the extra weight (between flanges) on your shoulder.
Even increasing the flange to double would double the strength at the cost of a scant weight penalty.

Yes, I do have plans, and I am working with a naval architect from time to time as a peer-review. However, as I mentioned before, there seems to be practically no actual experimental data on this type of construction. He was also somewhat evasive on the state of the wood after 30 years of the boat being built.
Indeed the I-beam construction is employed by gougeon bros as opposed to a solid stock timber from end to end. Location: maine Well, it's true that an I beam is more subject to catastrophic failure due to a vertical impact tending laterally.

Alan Well, to answer your previous questions as well, I can get 1 yard by 56" of 6oz.
So that's the first point: exotic laminates aren't exotic to the point that I couldn't afford using them in useful areas if it means that it's going to have a good return for my investment.
Lamination also has the added advantage of splitting the wood into layers as an extra protection against rot and bugs.
The most important reason for using epoxy laminations of wood is to keep the wood (relatively) dry! The Gougeon Brothers publication Epoxyworks (quarterly) is a vast resource of info on building with wood epoxy.

Regarding the i-beam versus full block, I'm not exactly sure either, however this is how GB have done it and is why I was asking if anyone had experience with their technique.
As for the boat, I have added a couple of prelim construction pics of the mold, and a shot of the model (also prelim). Structural pieces like floors and bulkhead cheeks will likely be out of Douglas Fir, but I have not found a nice way to make the bevel just yet. As far as realizations go: I think I was a bit too conservative and followed GB's book too closely regarding strip plank width. Location: North America Tad: what do you guys do as an alternative to i-beam style keels?


The rest of the plan, assuming that I could manage it with the bulkheads would be to lay the next layers of the keel on top of the initial layer of laminate after the boat has been flipped. Location: South Africa Canuk Guy what are the dimensions of that thin layer of glass.

This post is a summary of the brilliant Mormon Expression podcast episode, “How to Build a Transoceanic Vessel,” which demonstrates what it would take for Nephi to build a ship capable of crossing the ocean.
Before hitting the points, keep in mind that Nephi and his family have been traveling in the desert for 8 years. Several Book of Mormon verses indicate that Nephi’s family did not interact with any local inhabitants, so everything Nephi builds needs to be from scratch. Nephi finds iron in the rock that he needs to melt in order to make tools like hammers, saws, and thousands upon thousands of individual nails. The biggest problem is: to melt the iron, he needs a blast furnace that burns at 3,000 degrees. Various illustrations show Nephi building the boat on the beach and rolling it on logs into the sea. To bend the keel, Nephi first needs timber long enough, sturdy enough, and porous enough for the job. Nephi needs to make wool ropes and sails for the boat (besides the ropes needed for construction). Once the sheep are sheared, the wool needs to be stored in a way that prevents it from rotting.
All the freshwater for at least a dozen people for over 6 months would have to be collected, transported, and stored. It took a crew 40,000 man-hours to construct a Viking longboat replica using modern tools, pre-manufactured resources, and precut lumber.
Between 1991 and 2007 three A Class Catboats have been built at the Independence Seaport Museum's boat shop and one was built next door at the Philadelphia Ship Preservation Guild by members of the same crew. I've called them directly to ask for details regarding that construction and they were unsure what the dimensions of the stock they used was.
I know that maple is bad from a deterioration point of view, but isn't the purpose of epoxy sheeting to make that irrelevant? Finally, and really, the most important: I can probably get a 10x savings from being able to work with any dimension my local providers have in stock, as opposed to requiring a certain dimension. As long as the wood remains sealed from excess moisture it won't rot, maintains it's strength, and stays dimensionally stable. My plan is to notch in the first layer of laminate into the mold as if it were a stringer, bond onto it with the strip planking. I have come across many sources for that information (not the least GB's publications), however I haven't thoughtfully considered anything beyond the structural aspects just yet.
Their clothing, tools, and other belongings are very out of shape or have already been discarded.
Somehow, he needs to extract the iron from the rock and then make molds for the tools. How does he make tools without tools? Since a wood oven can only burn between 500 and 1,000 degrees, he needs charcoal (and technology that wouldn’t be available for another thousand years). Keep in mind that there were ancient craftsmen who spent their whole lives ONLY making keels because of the skill level needed to do it.


But such foods are perishable, so Nephi needs to gather all the correct foods and supplies beforehand and then create a pickling a pickling industry from scratch. The plans let in Nina from Carolina large sheets of drawings screening the hull at several stages of construction full size details Bay Pilot 18 focus on Console Power Bo. They also did mention that it did snap on the maiden voyage due to grounding, and that they had to make a thicker version for it. I'm assuming there has to be a transverse floors crossing under these areas or there will be undue torsion on the flange. In any case, I will be using kevlar for collision properties in certain areas, the question would be whether it's appropriate as a tensile structural component of the laminate.
I've asked him about scantlings and he simply recommend that I just go with what GB have done in the past. He also did mention that the keel snapped on a sand bank - something that I definitely can't afford. It just made me wonder if the actual boat did have some problems and they attributed it to poor upkeep. Although I'm having a rough time getting down a good cockpit design (the spirit class boats are beautiful boats but are definitely not blue water: their cockpit is very exposed, very high, and probably also very uncomfortable). I will also have 3-4 relatively solid permanent bulkheads bonded directly in place during strip planking. The charcoal needed for this project requires Nephi’s family to chop down acres and acres of forest using the tools that he has not yet made.
Assuming he learned about it by revelation, Nephi also has to fashion pulleys and more rope to make the rudder work.
If he uses animal skins, he has to have animals (which means even more sheep) and then spend several years treating the hides with tannic acid.

Without all the other thousand impossible steps, the construction process alone would take ages. Given that the area of the keel is maybe a total of, say 5" by say 5 feet, that's 2 square feet. I will be reinforcing key areas (along keel, on the flare of the bow, the bow itself, and the fore foot) with an initial layer of kevlar cloth under the layers of veneer, and a final layer of kevlar on the exterior. If Nephi received a revelation and made barrels he would need more timber and metal strappings.

It's difficult to transport, it's difficult to handle on the shop floor, it's difficult to work on, and it's also difficult to insure that it's dimensionally stable. It's also going to be very expensive (for example if I choose to use dimensionally stable, but ecologically unfriendly, and also expensive mahogany).
