Yes, functionality over performance for sure, though I do want it to look nice and be enjoyable to play with. (both for me and the upcoming batch of teenagers)Jaysen wrote: ↑Fri Jan 29, 2021 11:34 am I thought about this over night...
I have some concerns about needing stays/shrouds on this thing...
1. The stays/shrouds will put a lot of downward pressure on the keel seam under the mast and a lot of upward pressure on the thwarts (or wherever you decide to attach them).
2. Stays/shrouds need to be tensioned properly. That means lots of setup time.
3. Stays are kind of a performance things in little scooters. Like race performance. I think you will get MORE than enough speed and might want to consider #2 over performance.
I think I would recommend a config that uses a capturing step and a mast partner over stays/shrouds. A lot simpler.
This is where my lack of experience really shines..... a big stick poking up into the sky with a kite attached to it....... is two points of attachment a foot apart enough to fight that much leverage? I even had someone go the other direction with recommending that I would likely need spreaders to prevent the mast from acting like a wet noodle.... I just don't know the physics of it, nor the math to calculate anything like that other than reverse engineering or following someone elses plans.
yes, I was going to figure out daggerboard placement last as I do know they need to be balanced with the sail. I am planning to put them in the outriggers just so that its one less thing attached to the original canoe, I am sure I will need to do a few minor attaching modifications to the canoe but when its done ideally I can just bolt the canoe to beams and launch, then when I want a canoe I can unbolt it and its ready to go.... simple in my mind anyways......Jaysen wrote: ↑Fri Jan 29, 2021 11:34 am You also need to consider the CoE of the sail for the location of the dagger/lee board. if you don't get the right balance you wind up with either a frustrating or a dangerous end state. If the CoE is behind the dagger, you wind up with "weather helm" where the boat constantly points into the wind. This is frustrating as you wind up fighting to keep her on course. If you get COE in front of the dagger you have the apposite problem... always pointing lee. The problem here is that you wind up with a serious gybe potential and an increased risk of pitchpole/bow stuffage.
All the plans I have show the CoE aligned with the keel/dagger (it is actually aligned with the "center of resistance" on the non-BBC plans, I don't see a marked point on the BBC plans).
Might be worth asking JM to weigh in on mast and dagger/lee board placement.
My main project right now is the airplane, but I purchased the plans before they were completed, so this is my 'stay out of trouble' project while I am waiting for more things to do on it. It will at least keep my brain busy during the winter, and then hopefully have it figured out enough in the spring that when I have a good window to do the work put it all together. Its good and bad.... good that I can ponder things longer and sort out little details, bad in that things are simpler for me when I am physically doing them and stuff begins to make more sense and fall together more easily. (at this point I don't know what I am over thinking and what I am underthinking)
