Your...I stand corrected, it's actually 8 knots. Your response made me look it up, as I was going off of my memory of other peoples' stories. And it's not exactly a hard rule, but if you can't maintain a minimum speed of 8 knots, there is a penalty fee of $471 for "transit pilot delay" (http://www.noonsite.com/Members/sue/R2012-03-14-3)<br /><br />As for the idea that a displacement hull cannot exceed it's hull speed with enough power, that's a myth Dmitri. Hull Speed is not a physical speed limit like the speed of light, it's usually defined as the speed at which the standing bow wave period matches the waterline length of the boat, so that the stern of the boat is in the bottom of the standing wave, while the stern is high up the bow wave, and your engine is constantly trying to climb a hill of your own making... <br />"From a technical perspective, at hull speed the bow and stern waves interfere constructively, creating relatively large waves, and thus a relatively large value of wave drag. Though the term "hull speed" seems to suggest that it is some sort of "speed limit" for a boat, in fact drag for a displacement hull increases smoothly and at an increasing rate with speed as hull speed is approached and exceeded, often with no noticeable inflection at hull speed."<br />https://en.wikipedia.org/wiki/Hull_speed<br /><br />While most displacement hulls become incredibly inefficient beyond hull speed, requiring exponentially more power until the hull finally planes, it most certainly can be done. Your displacement simulator will tell you how much power would have been required to hit 12 knots; and 200 hp was just a guess, so I won't be shocked if it requires much more; but there is such a number so long as neither the bow nor stern is swamped by the effort, which can happen too.MoonShadowhttps://www.blogger.com/profile/07026735575577934205noreply@blogger.comtag:blogger.com,1999:blog-7334230772332433270.post-33470452718158390252017-04-12T16:26:38.465-06:002017-04-12T16:26:38.465-06:00Thanks for the reply, seems that would be a tough ...Thanks for the reply, seems that would be a tough job to fiberglass the shower/sauna.

But Quidnon has two masts with two sets of sails, so the inboard engine is already redundant. If the idea of *both* sets of sails AND the engine getting damaged beyond function still upsets you, then you could certainly carry another outboard as a backup, say a small one about 3 or 4 hp. A good size for a dingy, and very common around the world. In fact, I'd consider it a good idea to have a storage rack to hold a spare outboard engine. If you had the opportunity to acquire one in your travels on the cheap, you would have a place to hang it; and if you should cross the ocean and never need it, you could end up selling it somewhere that such engines demand a premium, far away from normal shipping ports. If I was to hazard a guess, I'd wager that a quality, used outboard engine in working order sells for more in Waterford, Ireland or Cape Farewell, Greenland than it would have cost you within 100 miles of the ports of San Diego, New Orleans or MiamiMoonShadowhttps://www.blogger.com/profile/07026735575577934205noreply@blogger.comtag:blogger.com,1999:blog-7334230772332433270.post-85711688462397969732017-04-12T15:41:50.840-06:002017-04-12T15:41:50.840-06:00Please don't spread false information.

I'...There is also the advantage of familiarity. I've never owned a boat with an inboard engine myself, but I've heard some real horror stories. But on the flip side, I've got quite a bit of exposure to the small outboard engines. I suspect that my own experiences are the most common; and whether or not you intend to learn how to repair your own engine or pay a mechanic, the more mechanics that know how to fix *your* particular engine, the less that such repairs would tend to cost, generally speaking. Also, you don't necessarily have to repair the engine at all. You could simply pull it out and sell it at the closest harbor as a fixer-upper, and use your stash-cash to buy another one already running. The swapping process isn't nearly as difficult as with an inboard engine, and there might even be cases that you would want to rent an outboard. For example, crossing the Panama Canal requires that your vessel be able to maintain 12 knots, so that you won't hold up commercial traffic. As I understand it, most personal craft just lie about this, but some will lease an overpowered outboard in order to be able to hit 12 knots. The exponetial nature of wavemaking power demand of a displacement boat like Quidnon suggests that it would take something like 200 hp to get Quidnon to 12 knots, but it might be doable if such a crossing were required. Once on the other side, you simply pull the rented outboard and return it to it's owner, and replace your 40 hp outboard back into it's inboard well, then re-attach it's fuel lines and controls.MoonShadowhttps://www.blogger.com/profile/07026735575577934205noreply@blogger.comtag:blogger.com,1999:blog-7334230772332433270.post-48135685997505335412017-04-12T12:45:47.516-06:002017-04-12T12:45:47.516-06:00The sauna/shower will be glassed over.

The idea is that the sole panel extends past the junction with the bulkhead portion of the hull by a few inches. It is supposed to reduce lateral slippage a little bit, by creating a swirl on the leeward side of the hull as the mass of water tries to flow from the leeward side and around the bottom of the boat. It would likely also make the junction easier to perform, and stronger, because it's no longer a pair of boards joining at two ends, but instead one board joining it's end into a t-juction with another board. Different wood junctions are available in that case. Also, rails wouldn't work well to support the ship during a dry out, because that would create a pressure point that the whole ship would have to be designed to direct the weight towards, lest it collapse under it's own weight once the ballast was installed on the first dry out. Quidnon has a copperred bottom, in part, to accept and spread out the weight across the bottom of the ship, so that it can handle both a sand dry out, and hopefully also beaching on rocks.MoonShadowhttps://www.blogger.com/profile/07026735575577934205noreply@blogger.comtag:blogger.com,1999:blog-7334230772332433270.post-42792578461182192102017-04-08T20:38:40.708-06:002017-04-08T20:38:40.708-06:00Am interested in the chine runners: how they work,...Am interested in the chine runners: how they work, why you believe they are needed and their construction and mounting. <br />Do they extend down, out or both? <br />If down, are there similar 'skids' spaced along the length of the bottom to share the weight when rolling up/beaching?
