"tent" type dinghy
OK, I do not want an inflatable dinghy cuz they row poorly. My
original dinghy was 8' of fiberglass and very heavy and took up too much space. Portaboats (folding dinghy) is both heavy and makes too much windage leaning against stanchions, my Two-paw-9 nesting dinghy is also too heavy and a pain to assemble in spite of my advanced L bracket and clamp system replacing the original bolts. SO, what I want is a dinghy that works like a modern backpacking tent, held "up" by tension of strong but lightweight poles. Two longitudinal ones at gunwales, one at the keel, one across transom , one across center and then all joined at the bow. This should have light weight fabric over it with reinforcing at stress and wear points. The center crossbeam should hold a seat for good rowing efficiency and another at the rear for a passenger. Does such a thing exist? Is any design available? |

I don't think fabric will work out for a dinghy. Simply too fragile. Dinghys lead a hard life. They don't look all that rugged but Platt Monfort's boats have a following: http://gaboats.com/ I once saw one somewhere in our travels. |

Does such a thing exist? Is any design available? I have tried every kind of dingy I can find. And just like you, they are either too big, tip too easy or just a pain in the but. I needed something that would fold easy and sit on the wing nets on my trimaran. So here is what I found, even has a sail adaptation if desired. http://www.duckworksbbs.com/plans/or...dex.htm#Videos I just started mine, all cut out and just waiting for warmer weather so I can epoxy coat and paint it. Have had it dry assembled and it is amazing. I am using clear fabric, so I can see below. Has partial wooden floor boards, so you do not sit on the fabric. Folds up nicely (less than 5 minutes). Only problem I had was one misprint in the plans and the weight. Most builders are coming in at 40pds or so. Mine is 40pds without paint or epoxy. |

For some value of 'tension' that reflects the fact that tent poles are always loaded in compression. Give or take lift from wind. In the latter case the poles carry no significant loads. Casady I didn't write that I guess I need to learn how to read. Don't take it personel I just answer posts and none of it is ever personel . I didn't set out to somehow libel someone. Casady |

Lots of good advice *but* here's a quote from the West System site at http://www.westsystem.com/ewmag/18/tanks.html ==== While professional builders are bound by tough USCG regulations and ABYC standards regarding tanks, backyard-boat builders have the option to follow or disregard them. However, if the builder decides to sell the boat, the federal regulations become applicable because he/she has built the boat for the purposes of sale. ==== That is my understanding also. From the introduction of COMDTPUB P16761.3B at http://www.uscg.mil/d1/units/actny/p...dBoatBldrs.pdf This pamphlet is routinely sent to new manufacturers of recreational boats for the purposes of sale, because it gives a good explanation of how to go about complying with certain portions of the Federal safety standards and regulations. |

Here is a simple idea: Add some straps to the fold-out design, and tie your fenders under them when you use the dinghy. They give at least some flotation, and may be easily available while your boat is on anchor somewhere... Probably not living up to the legal requirements in some places, but might work. Sufficiet flotation would have obvious safety benefits, but even a little would make the thing easier to find if ,you happrn to swamp it. My dad lost my favorite boat when I was a kid. In twenty feet of frest water. Casady |

So I guess it does not need added floatation. If someone was real worried about it, you could add foam water pipe tubing to the top of the plywood sides. 2- 6 foot pieces of foam would easily hold 200 pds afloat. We only use one in physical therapy, and it keeps my 180pds afloat. Also foam would protect sides from dock rub. If you used an outboard, then yes extra floatation would be needed, but I row. |

If you used an outboard, then yes extra floatation would be needed, but I row.- Hide quoted text - - Show quoted text - Well, exactly how many pounds of float does your boat have, full of equipment, and your kids? Seriously, when I first started building boats in my backyard nearly 2 decades ago I went through hell and the US Mail (no internet then) and ordered the rules from a nice Commadant in Virginia. It was a book nearly 4 inches thick and I got updates every year. You can all guess what you want, but the regs are clear, and the USCG is still the accepted regulator. The pamphlet I noted above is for any and all boats built, weather sold or not, powered or not, even if many natural powered are exempted, they are still addressed.. I won't argue with you guys here. Anyway, I always mumbled about the rules till I struck up a friendship with a USCG rescue diver. He told me that in 20years he had never had to come to the aid of a homebuilt. Now this was a long time ago, before the internet brought this fine hobby to the masses who could before then only watch from afar. But now it is different, anyone can (and should) build a boat but not everyone is as versed in boats as the old days when you had to learn from a builder and probably were a pretty good boater to boot to take on such a project. The rules accomodate folks that don't know, what they don't know and if they are a little stringent, it allows for some leeway or mistakes by an amateur builder so he can still have a safe boat. Take the calculations for flotation for instance. If you follow the rules, and many don't, putting all that flotation, in the configuration called for by way of your calculattion, flotation can be a real pain in the ass. It takes up a lot of room, and if you use the right stuff, it can add a lot of cost to the build. And why the hell doesn't the USCG understand that wood floats!?? Well they do, but with respect to the average Joe, they don't include it for our own protection. Sure wood floats, when it is is dry and new but folks have been known to float around in less than dry hulls;) I know the cost of putting flotation, especially in a small boat can equal the materials in the hull, but it's part of the boat. I know, I have had to work it into dozens of boats over the years. Makes it pretty hard to compete sometimes, especially if other guys are selling illegal hulls.. There were some videos posted here several years back of a builders meet. A couple of unfloated boats sank in a small pond with a slight breeze. The guys could not get back in cause the boats did not have proper flotation to be recovered, so these less than physical specimens (with no jackets either) had to swim the boats back to shore. After several minutes of getting nowhere with the breeze aginst them, other boats came in a dragged them to shore. The one guy almost dropped of a frekin' heart attack. If he had proper flotation in the kayak, he could have gotten back in and bailed her out and saved the boat. As it was if there had been no boats around on a larger lake, these guys would have lost their boats, an one of them would have probably died too... Anyway to avoid or eliminate flotation after building a nice hull is cheap and irresponsible,in my opinion. Noting personal, not everyone feels as I do, so I won't throw stones here. But for the sake of honesty, lets all know that all boats built, sold, or used in the US, under 20 feet, are subject to these rules, for very good reasons. Sorry this is so long, I am very busy and don't have time to go back over it, but it is a very important subject. hope someone gets something out of it... Scotty from Smallboats.com... |
