24 hour HPB record

Greg Kolodziejzyk — 2008-07-22T22:48:50

Hi - not sure how many of you have been following my latest progress, so I thought I would give you a quick update for anyone interested. I hit 16 kph (10 mph) the other day, and finished a 5 hour circuit on the lake here with 11.4 km/hr average speed (7 mph, 35 miles) http://www.adventuresofgreg.com/HPB/uploaded_images/P7200014-728295.JPG More pictures and a video of the 10 mph run here: http://www.adventuresofgreg.com/HPB/2008/07/fairing-test-10-mph.html Greg K

Displacement hydrofoils

2008-07-19T16:50:49

Most hydrofoil designs have relatively thin bladed foils for "flying" mode and auxiliary floats for "floating" mode. Does anyone know of any designs that have fatter foils that make flying more of a cross between the two modes? If so, how is the overall performance? Could this be an option for a long distance hydrofoil design that wouldn't require superhuman strength and endurance? Michael Lampi

Open Sourcery iii codes

2008-07-16T22:54:40

Bob, all, I have been working on a building for too long now and there are good and bad about codes. The good is that it sifts out some problems in safety , corner cutting, etc. Good for safety. I make sure as best as I can that I'm anal about quality. If the code specifies a certain structural size or insulation amount, I usually end up a notch or two over the spec .It is not so bad to have a staircase a little wider (carry up hydrofoil) or make the place a little less expensive to keep warm, or have the place jiggle less when you jump up and down on the second floor. Also good for not having to worry about a hog farm next to your condo complex, a dog kennel (constant barking) next door... Bad thing is the idea of having to report to someone about all your stuff sounds sort of a combination of buraeucratic and dictitorial... Oh well.... jake **************Get the scoop on last night's hottest shows and the live music scene in your area - Check out TourTracker.com! (http://www

Open Sourcery ii Drive Unit Foot Ergo Specifications for Catamaran, Proa, etc.

2008-07-16T22:38:24

Giu - 2 Parameters may include ergonometrics for the feet. In your site, the model sitting on the Talssociclo is qualified as very OK (grin), but there have to be some parameters you have to address. Heel clearance: if it's too low, cyclists who want to stay dry won't in wether that you could still navigate in. In other words, it is wavy out, but not enough to be scared about, or force you to come ashore. The height of the heels above the water should address this. It is amazing how many boats I've seen and ridden have not addressed this tradeoff. OTOH, if the pedal bracket is too high the butt placement will get driven up too far and the CG will be too high and so on. The relationship should be Water to heel at the lowest part of the pedal stroke, centering that to the pedal bracket, pedal bracket to the seat bottom! Which indirectly influences the width of the hulls! Mount Standardization. There should be a vertical-plane spec. that includes a tolerance to being vertical and perpe

Giuseppe, Bob, I agree that there would be varieties of a class of boat (such as a HP catamaran), and it would be good to establish a group of PARAMETERS, variables in the design, and PRIORITIZE them. What are the most important? What complete class branches can or must we come up with? i.e. a catamaran pack boat is one that is important enough to pursue? Or one that I hear the most, speed...? I too have been introducung additional parameters (other than speed that is) to this sport. High on the list includes *habitability, comfort *ease of takedown, assembly *efficiency (the late Bill Murphy won a "captains surprise" at the race one time by having his rig rotate the most times when spun) *Well made!! Long lasting, dependable etc. *Low maintenance: I ran a hydrofoil in the '90s that took more energy to set up and keep tuned than to run. But the head-turning factor was worth it ;-) While some concepts related to open source really creep me out like politics, charlotinism, stealing

gmane bikelist board

Rick Willoughby — 2008-07-15T00:32:47

The gmane board seems a poor service. The history gets lost and the board goes down regularly. I suggest the HPBers take a look at: http://boatdesign.net/forums/ This seems to offer a very good alternative. There is some nonsense on the site but it provides an excellent platform. It will accept all manner of files so very easy to post photos and video clips. Very rarely goes down. Has an extensive following and a wide range of knowledge. Also as fuel prices soar there are a lot of boaties looking for less expensive ways to get on the water. Human power is gaining increasing use. Still not many convinced on the virtues of pedal power but that is something we can lead. I will start a new thread for pedal power. Rick Willoughby

QUESTIONS FOR GIUSEPPE: Hey guys, I would do a metaphor of boat building and inventing to musical performance. Sometimes yopu have a symphony. Lots of differing individuals with varying degrees of talent, and fur sure differing specialties. If you propose an open source, how would you treat musicians with seniority? Now for the "64.00 question": What about virtuosos? Who would conduct the symphony? There are other parallels; What about a sports team. Perhaps there are only a given number of openings on the team...? Who would coach? who would play what position? More questions later.

New drive leg

Ian Cassell — 2008-07-10T00:41:22

Finished my drive leg and worked ok, boat was not as fast but at least it worked. It consists of an involute gear box angled at 45 deg with two universal joints connected to a 450mm prop. The boat was a bit slower than with the shaft and drive in the boat, advantage was transport and turned a lot tighter probably from having the prop in the middle and not at the end. Disadvantage was the big hole (100mm x 1000mm) to fit the drive leg, this has weakened the boat and when pedaling hard the drive wobbles a bit to the point where I sprang a few small leaks. One problem in raising the drive leg was getting the prop into the vertical position to lift it through the hole, without the outriggers I would have gone for a swim. Ian Cassell

Open water bike

Ian Cassell — 2008-06-13T03:55:50

Giuseppe How do your drive legs work? Do you use gears, chains, belts or whatever. To me the start point for your open water bike project should be a reliable drive leg that could be fitted to any type of boat, the variable would be a range of different propellers to suit speed and power. I am making a driveleg using an involute gear box with a 3:1 gearing, the gearbox is angled at 45 degrees with two universal joints connecting to the propeller so the prop spins vertically. My boat is a 5 metre monohull with outriggers, it has a centreboard casing for the driveleg and hopefully this should work (nearly finished). If you would like some pics let me know. Ian Cassell

The Open Waterbike Project revised

Giuseppe Carignani — 2008-06-09T09:44:31

Dear colleagues and friends I have carefully considered all your comments of The Open Waterbike Project and I have therefore revised the project and updated the website. Most of the comments made sense to me, and this shows that often strong criticism is often more useful than praise... I hope I have provided an answer to Alex et al. (who said: ...I'd really like to ask what the aim of any OpenSource boat is first, because without that I really do think it's a no-goer...) at the page, in which I tried to summarize the requirements of an Open Waterbike: http://www.openwaterbike.com/architecture/the-open-waterbike-requirements and I'd really appreciate your opinion! I'd like also to stress that racing HPVs and leisure HPVs are possibly not as far apart as Alex believes, as all the history of technological change, e.g. the history of the bycicle, shows. Finally, I'd like to comment of who said that we don't need an 'Open Waterbike' since we have already some nice mass-produced pedal-boats like the Hobie M

catamaran waterbike on the waves...

Rick Willoughby — 2008-06-08T04:13:23

Giuseppe I posted a reply to this on my travels but it did not get through. You should look at the Rocat hulls: http://www.rocat.co.uk/ You would need to mount the pod to face forward and also provide good fairing on it but the boat has proven safe in heavy conditions. There may be hulls available as I believe they stopped production. The boat would be a better performer in rough water with pedal power. Remember you are giving away a lot of performance to s stabilised single hull. The cat will require about 40% more power for the same speed as a good mono with outriggers. It is similar in basic dimensions to my V4 boat: http://www.rickwill.bigpondhosting.com/web_photos_video/video_v4.wmv It is quite safe in rough water but gets very wet because there is no fairing in front of the seat. The front cross brace punches through waves and makes it very wet. Rick Willoughby rickwill-bzGI/hKkdgQnC9Muvcwxkw< at >public.gmane.org 03 9796 2415 0419 104 821

Father's Day purchase

2008-06-07T19:10:25

After seeing the results from Rick's GPS/heart rate monitor remotely as well as live, and after a *lot* of hemming and hawing, I decided to take advantage of a Costco.com deal and buy the Garmin Forerunner 305 GPS/heart rate monitor. The deal ($179 w/shipping) expires tomorrow, so if *you* want one of these babies you'll have to hustle. With luck it might arrive in time for the next Sound Rowers race. Anyway, if the GPS/monitor works as advertised I'll also get the cadence sensor. Some of the reviews disparaged the accuracy of the Garmin GPS, and even the heart rate monitor, so I'll make sure to take along the Magellan for distance and speed comparison purposes. --Michael Lampi

Giuseppe Carignani — 2008-05-27T16:26:42

Hi everybody any piece of advice for a catamaran waterbike to be used not only in calm waters but also on the ocean, with waves some 1 m high? Best distance between the hulls, hull length and shape in your experience? We have little experience on choppy waters... Requests at the Open Waterbike website are coming earlier than I thought...

Open Waterbike

Ian Cassell — 2008-05-25T09:34:47

Just got back from holidays and have read through all the emails, even when you tell people you are away they still keep sending them. Anyway, read the important ones ( the ones for hpv-boats ) and Giuseppe has started quite a debate. His open waterbike project is an interesting idea, but one type of boat will not satisfy everyone. I think hpv boats have to be like bikes, different types for different applications. The road time trial bike is the fastest but try it on a dirt road or touring and it wouldn't last long, same for hpv-boats, Greg K's 24hr boat is the fastest as long as the water is calm and not much wind. Maybe Giuseppe you could offer a few different boats river, ocean, racing, touring. My criteria for a boat is weight, transport, launching. Weight is light enough to be carried by one person. Transport is small enough to be carried on a cars roof racks. Launching is being able to go from a beach or riverbank. Thats my two cents worth. Ian Cassell

Outing on Lake Union with Rick Willoughby

2008-05-25T00:13:35

I spent a rather glorious morning and early afternoon on Lake Union with Rick and his wife Rhonda. Rick tried out the Cadence while Rhonda pedaled the Escapade. I sat in the back of the Escapade and took pictures and videos. Thank you, Rhonda, for pedaling me all around the lake! Unfortunately, however, I left the camcorder in the car so the videos are those taken by the camera. This means they are rather large and not of as good quality as I had planned. The photos and videos can be seen at http://snorlax.lampi.org/images/Lake%20Union%20RW%202008-05-24/index.html Enjoy! Michael Lampi

The Open Waterbike Project - Matabolic Rate

2008-05-24T04:57:07

Vic The best comparison come from racing. Over time you get an idea of what performs the best under what conditions. It would be very interesting to see what would develop out of an unlimited class of pedal boats that had a strong following and regular racing. I suggest this is not likely to happen. For now I think it is hard to better the Hobie Mirage as a pedal boat for the masses. My interest is really different as my target is more toward an unlimited racing craft only constrained by the laws of physics. Anyhow we should be grateful to Guiseppe for generating some new debate. Where is Dan Grow? Rick

The Open Waterbike Project - Matabolic Rate

2008-05-23T14:52:29

Guiseppe I just read your latest post on the power reading and now understand it is overall metabolic output. It is in close agreement to what I have determined from less direct measurement. I have stated on the IHPVA site before that I believe my V11 boat is the most efficient long range human powered boat. Hopefully this will be proven with no doubt over the next few months. Again, I believe there is a large gap between overall efficiency and having something that is marketable. The Hobie proves this. Rick Willoughby
