@@SvenYrvindExlex Even Sam teases Sam about his hole drilling. Thank God his drill finally died. It was only a matter of time before he drilled a hole below the water line. 😁
That's a great setup. Question; if the line breaks at sea are you able to reach the daggerboard in the down position? Or will you put an emergency retrieval line on it? Or do you think thats overkill to a problem that most likely won't happen?
Looks good Sven. Depending on sailing qualities of existing keel, to be seen, i was thinking of a ballasted swing keel located at the center of lateral resistance (clr) but have limited access in my shallow draft hull and i see your daggerboard case certainly takes less space. Only wish i had your strength snd determination. Maybe, hopefully our courses will cross one day.
By having an adjustable forward daggerboard, it allows him to easily adjust where the CLA is. This is very helpful when trimming the boat for different points of sail and for different sail configurations.
@TJF-f5l theoretically, all types of sail that are usually adopted. The simplist application is an adjustable centerboard or lee boards where it is easy to change the amount of board under water. Unless the centerboard is exactly in the center of a forward/aft symmetrical wetted hull area, the CLA will change some as you lower or raise the board. But having the daggerboard far forward allows much more percentage change in the overall CLA for small changes in the depth of the dagger board, making adjustment of lee/weather helm at different points of sail very easy and effective. Of course the down side is complexity, loss of storage, more lines, another hole in the boat etc. Almost nothing is free.
In my little brain I saw instead of using boring planks for lateral stability or a so called keel why not use big heavy metal demolition hammer’s that have extra strong polycarbonate plastic handles.A line of them could easily become glued together or tied making a bloody strong weighted super keel.
There is only disadvantages of having the daggrer board higher than the hull. Center of gravity gets higher, but mostly it will interfere with boom of the sail
@@stefantornblom1555 True. I must hoist the daggerboard higher than the deck to make it flush with the bottom of the hull. It is still a bit higher than the the deck. The dagger board is quite long. As long as I can make it. The bottom of the hull and the boom is what limits it.
At sSea, there might be little more power required if wind is pushing the boat but should be ok. What about mixing graphite powder with epoxy on the final layer of the keel, that will make it slippery/ and black)?
Pretty cool! I like it.
I should have done this on previus boats.
I am learning
@@SvenYrvindExlex Never too late for putting a good idea to use.
As always, fine work. I know nothing about sailing but everything you do makes sense to me 😊
It will only get better when the glass makes it heavier and smoother. Great idea and very nice work. I'll bet Sam Holms is jealous as hell!
Poor Sam

Sam b.Sailing
I would add additional support on both sides of the tunnel to prevent bending end possible demnage because of side forces...
It will be supported by the deck, I think, more than enough.
Be paitent.
I am still building.
Attach the pull string lower on the board, dont need the height above deck to lift.

WOW, Captain Sven, it looks really good.✝️🙏❤️🇺🇸⛵️👣🍍☘️🤗
Very good job

Hi Yrvind, when I look at 0:16 it seems like you have left the foam core exposed, am I missing something here?
The Divinycell is exposed. But it is inert and do not rot nor absorb water so its OK
Very good. I'm presuming it will be weighted to drop down and not float.
It will be epoxylaminate G11 density 2.0, sinks like a stone
Good work, et gravity do it. Is the rake of the dagger board slightly forward in a seaweed catching angle.?
It is straight down. Maybee the boat have anngle. I did not make it level.
Is the entire length of those slots above the water line? I worry about things growing in hard to clean places.
What is the reason for locating the daggerboard near the bow, instead of closer to the middle of the boat?
Thank you.

Thank you.
Does that concept work for all sorts of sail configurations? Or just the kind he’s using on this boat?

If you place the upphaul connection as close to the hull as possible, when the daggerboard is down you can hoist it higher.
There is only disadvantages of having the daggrer board higher than the hull.

@ ok in the mockup it looked like you must hoist the daggerboard higher than deck level to make it flush with the bottom of the hull.

I newer had problems pulling the dagger board up.
👍👍
Compared to the removed CB this dagger board looks very narrow in length. Won't this affect the sailing performance in terms of directional stability?
My experiences with the 2 previus Exlex says it will be OK. They had excellent directional stability I did not need wind vane or autiopilot.
Will you have lead in the board to help overcome the natural buoyancy of the board? or will you have another mechanism to pull the board down?
It will be G11 epoxylaminate. Density 2.0. Sinks like a stone.
@@SvenYrvindExlex Great 👍
👍
¿ No es demasiado fina la orza y frágil?!
It is just the mock up.
All my admiration for you!
