I talk about it all the time to my wife. Trying to get her buy in is a hard sell, but this is my favourite daydream, so I may have to leave her to live my golden years as a sailor or marina rat. I've never owned a boat before and barely know how to sail, but this sounds great to me. <br /> <br />My questions and comments are coming from the nautical novice fringe, but are informed by my experience as a carpenter and architect. BTW I'm pretty good with CAD software, maybe I could help the project along? You don't need to post this or even reply. I just wanted to get these ideas into your mental hopper in case they'd hadn't been considered, which isn't very likely.<br /> <br />I just love reading and rereading all the Quidon design development posts and have great faith in your dream Dmitry. I'm ready to sell my big house and downsize on almost any provocation, when that happens the first $50K is being set aside for my Quidnon HouseBoat. <br /> <br />My questions: <br /> <br />1. The chimneys for the stoves, where are they mounted on the exterior? Do they penetrate the side wall or the deck? Will they have a protective heat shroud like the exhaust pipe on an 18 wheeler? What is to stop water from coming down the pipe during a storm at sea? Is there an escape vent for that water? <br /><br /><br />2. The railings around the deck, what sort of hardware detail or railing system is planned? For maximum flexibility you'd want a sectional system where the wire ropes between the posts are easily removed for loading of gear/ freight to the deck, right? Are the posts surface mounted or is there a metal sleeve drilled into the deck that receives the post and fixes it with a twist lock action? If water gets into the sleeve is there a drain vent path for water to escape? It would be joint/ penetration prone to damage and an infiltration point to unprotected plywood. It could be a weak spot in the design if not well considered. <br /><br />3. If the boat were to take on significant water for a short time the walls and built in furniture should be detailed to allow for ventilation without disassembly, and treated to prevent the plywood from swelling up like oatmeal at the first hint of water. Are the interior deck/ floor boards removable in a systematic fashion with just a screw gun? <br /><br />4. Thinking about the floor, I'm wondering if long term storage items, for emergencies, could be stored under the floor while still maintaining air flow for heating in the the underfloor plenum? Things like extra keel boards and rudder, extra rope, chain & anchor, another propeller, that don't care if they get flooded. <br />5. How does the companion way door seal out stormwater? Or how does it manage the water that will inevitably spill down the stair? Will there be a recess in the floor there, or gaps in the floor boards with a drip collection pan underneath and a pump? <br /><br />6. I'm 6'-3" and would like to have 6'-5" clear in most spaces. Is there an option to order 12' long plywood for the side walls and suffer a bit of waste to gain an extra foot of height for headroom, ceiling cavity, and increased underfloor storage/ plenum? It shouldn't be too hard to stretch the height in the software, but would we be able to make good use of the cut offs for interior furniture or other parts? <br /> <br />I think that's it for me and my bright ideas. This is what you get when your dream catches fire with other dreamers. Love your work Dmitry, and I hope you and your family are able to ride out this pandemic in splendid isolation in a lovely little marina or lagoon somewhere. <br />Sincerely, Jake <br />Unknownhttps://www.blogger.com/profile/17154533651494617582noreply@blogger.comtag:blogger.com,1999:blog-7334230772332433270.post-52720458565381056762020-04-04T14:36:23.055-06:002020-04-04T14:36:23.055-06:00The dual keel boards make sense.

How does Dave Zeiger deal with the "uneven" tension on the sail. <br /><br />Just looking at it (and I have no experience with sail design.., what if you move the attachment point of the upper block farther forward on each batten. Wouldn't that increase the tension on that portion of the sheet and help balance the increased force when reefed?<br /><br />I'm asking "cause" I want to learn something.

I did all sorts of sheeting experiments. I was not willing to invest in expensive blocks and found that one continuous sheet had too much friction. Then I tried a separate sheet for each batten. That gave a lot of control but a bit too cumbersome. So I settled on tow sheets, one for the boom and first batten up and then another for the next tow battens. I can then control twist by tightening one or the other. This has worked very well, not perfect but very good.

I suspect that the idea, if not the exact method, will outlive us all. On that note, I've noticed that with your design requirement that Quidnon be sail-able entirely from the cockpit, that it's also going to be ideal for autonomous/computer controlled sailing. Replace your locking sheet block control line with a pneumatic break pin, the take up spools with electric winches, and your sheet clutches with pneumatic cleats/clutches; and it becomes possible (not trivial) to program a Raspberry Pi as an autopilot that can sail Quidnon in changing winds for hours at a time, or sheet back the sails and wake the "watch". Combined with your controllable tiller mounted autopilot, it might even be able to sail a pre-programmed path "zero-handed" in some predictable waters.Anonymoushttps://www.blogger.com/profile/03887549418645633812noreply@blogger.comtag:blogger.com,1999:blog-7334230772332433270.post-67328448489728788812020-03-07T16:46:22.833-06:002020-03-07T16:46:22.833-06:00Aha yes, an advantage of a lateen sail as opposed ...Aha yes, an advantage of a lateen sail as opposed to a marconi is you don't get twist, due to the top boom. An especially visually pretty rig, the schooner rig, seems me to be an attempt to get the best of both worlds, large sails that are a hybrid lateen/marconi. <br /><br />You could probably buy any old tub of a catboat to test sail rigs etc with .... cheap. alex carterhttps://www.blogger.com/profile/12458022111793552536noreply@blogger.comtag:blogger.com,1999:blog-7334230772332433270.post-73455859597667645582020-03-01T13:38:34.192-06:002020-03-01T13:38:34.192-06:00I'd like to build a dinghy to test out the kic...I'd like to build a dinghy to test out the kick-up appendages and the sailing rig, mostly.<br /><br />The usual modern sails are stitched or laminated out of nonstretch materials such as Dacron and carbon fibre to have a certain aerodynamic shape. In racing, there are also certain adjustments, such as the Cunningham, which can reduce the belly of the sail in stronger winds. Quidnon's rig is different. It is best viewed as a stack of Lateen sails. The panels between the boom, the battens and the gaff all form conic sections, which make perfectly good airfoils and create plenty of lift. The equivalent of belly can be adjusted by tightening or loosening the leach of the sail. In the case of Quidnon, this can be fine-tuned using the reefing line and the halyard.<br /><br />What I meant by "flat" is not that, though, but the avoidance of twist, which simply spills the wind out the top of the sail, generating no lift. That's the problem I believe I have solved.Dmitry Orlovhttps://www.blogger.com/profile/00381674543530177679noreply@blogger.comtag:blogger.com,1999:blog-7334230772332433270.post-54089783379037200812020-03-01T11:44:32.812-06:002020-03-01T11:44:32.812-06:00I wonder if a "dinghy-non" would make a ...I wonder if a "dinghy-non" would make a good test platform for sail design. A lot of dinghies or "cat boats" are small, but will have a main and a jib, and a boat like that set up with a Quidnon-type sail system could give you some valuable experience. <br /><br />I'd like to mention that keeping sails flat generally isn't a goal of modern sail designs. Just keeping them to a shape that viewed from the top, looks like the top surface of an airplane wing. In a sailing class I learned that if you have to make use of the smallest whiff of wind, you lean the boat purposefully to get the sail to "belly" out a bit, and it works far better than sitting straight up with a flat sail. alex carterhttps://www.blogger.com/profile/12458022111793552536noreply@blogger.comtag:blogger.com,1999:blog-7334230772332433270.post-59125535479788792482020-02-29T11:53:06.365-06:002020-02-29T11:53:06.365-06:00Woohoo, Quidnon!

I make the Kootenay Doukhobor version which is strictly vegetarian. It is a staple in my freezer. I will miss that freezer if or rather when collapse happens. <br /><br />I have expressed the impolite opinion that an epidemic that mostly kills old people might be a welcome development, and if that includes yours truly, so be it. I would love another decade but at 76 will not feel cheated if this is it. What I fear is not death but discomfort. <br />After a lifetime of sort of prepping on an acreage I plan to move into the village this summer. My main selfish worry right now is: will the interruption in supply chains interfere with the delivery of the modular home I have ordered? <br /><br />Meanwhile the political landscape in the West has gone bonkers with extreme political correctness. If you want to have a laugh, google Yaniv. It does look like the gods wish to destroy us. Merry prepping everyone.<br /><br /><br />Ien in the Kootenayshttps://www.blogger.com/profile/01766317652520657570noreply@blogger.comtag:blogger.com,1999:blog-7334230772332433270.post-32520802225622253612020-02-29T11:33:25.467-06:002020-02-29T11:33:25.467-06:00Sounds great!
