I'm currently engaged in a project to design a large, ocean going, multihull rowing vessel.
I should probably add that my line of work is in designing equipment for Ocean Rowing, and I would be glad to add my input to any other rowing related queries.
Chris Ostlind Previous Member   Take a look at Jim Antrim's approach to multihull rowing. If you are after overall efficiency get away from rowing and go for pedal driven prop in a slender aerodynamic monohull. It is set up for single person but would also suit two up on rotating watch for long distance.
It is possible to determine the lowest drag hull shape for set constraints and something I have addressed with a number of designs. Rowing shells are close to optimum shape for the installed power and weight whether 1, 2, 4 or 8. Location: Portscatho Thanks Chris - I'm well aware of Orca and his other projects. I have discovered that there is an American team working on a vessel designed by Morelli and Melvin, though whether she will simply be a modified version of Playstation(!?) or a complete new design remains to be seen.

The people who purchased Rocats were generally disappointed with performance against other rowing and paddled craft. Unless you have tried a well designed pedal craft you really cannot appreciate the advantage over stone age technology of rowing. The outriggers on this hull are designed to be very lightly loaded so they contributed almost nothing to drag but offer good initial stability. In a seaway the ability to apply power efficiently and consistently in all sorts of weather conditions with a propeller is a significant advantage over rowing. However the hull forms my colleague are I generally use when appropriate (see caveat above) is the series 64. Any way, this is academic as this vessel is intended to compete in rowing races and record attempts against other oar powered craft.
To be of any value to the customer, this design must average 4.2 knots over 30 days on a rhumb line passage of 3000 miles. I agree that catamaran configuration is NOT the way to do this, as I stated in my first post. Ad Hoc - I will do a little digging and see what I can unearth regarding the 64 series - it sounds like the right direction for the design.
This software and its derivative have been used for optimising many vessel types ranging from Australian olympic rowing shells to US military craft.
There is great value in knowing what the best possible hull form looks like and what various constraints might cost in terms of performance. Guest625101138 Previous Member   Just to bring home the point on pedal power over rowing. Given the rough values you have, then clearly the lowest froude range is better, the 0.24, with a length of some 16m even this is pushing it at some 6knots! The fact that a simple rough calculation, as above, demonstrates you have a tall order, in designing your vessel. Many years ago i had a nice chat with Nigel Irens at a RINA conference we were both presenting, nice bloke. If you look at overall efficiency from oxygen uptake for rower versus pedaller of similar trained ability, using more precise hull data, you arrive at a rower achieving an overall efficiency of 14% compared with a pedaller achieving 22% - so the rower is going to expend 50% more energy to go the same distance at the same speed.
However, the paper is no different to many others, as such all taken as interesting but not too literally.
Weight of personnel is 1.28t so a well constructed hull with provisions for say 20 days might get as low as 2t.


You would need to go into complete detail on provisions and essentials such as water maker, comms, batteries, solar collectors etc to iterate on the weight estimate. There would be little loss in performance by shortening the bow and stern to remove the concavity evident in the plan view. Location: Melbourne, Australia Are you still engaged in your project of building a multihull ocean rowing vessel? When making potentially dangerous or financial decisions, always employ and consult appropriate professionals.
A hi-tech ocean rowboat is now available for you to use when you want to row and stay for a while in the ocean.

Her friend, Betsy, believes they put up work together and get along up with something creative that will make U.S.
This custom range model made by Premier Ship Models is a perfect replica of an ocean rowing boat, and depicts much of the design features of the original boat. Models like these support the fact that Premier Ship Models is known for its expertise in the model making industry. The ocean rowing boats are participating vessels in the sport of ocean rowing which dates back to 1890’s. John Fairfax was the first person to cross the Atlantic Ocean in 1969 when he took off from Gran Canaria heading towards Florida. Apart from this unique ship model, you can browse the Premier Ship Models website for other exceptional custom made boats, yacht, historical ships, tankers or carriers. The ship model arrived in great shape and was easy to put together (mast, sails, etc.)  Thanks very much! Confirm ordered the model on line today 3 April again your service and salesmanship was impeccable and excellent.
Be a part of the first mixed team of rowers to make landfall in South America having crossed the Atlantic. Two ocean rowing record holders build these specialist boats for long distance rowing events. I will be working on the foundations of Nigel Irens iLAN designs, and have a feeling (unsubstantiated as yet) that the concept will work well when applied to lower speed regime ocean going craft.
Marine definitions do tend to confuse people who are not naval architects owing to clever marketing! Naturally favourable weather conditions will assist this, but in reality the distance that they will travel will be greater. Wetted surface will contribute the greatest proportion of my resistance quota, but I am sure that there must be, or have been tests carried out on hullforms designed to operate at low Fn. The requirements of carrying sufficient food, water, power and ancillary equipment makes this a difficult task. As well as the drag penalty incurred at this speed, it raises serious practical snags for a rowing boat. Also, whilst we are on the subject, I do appreciate that a stabilised monohull is not, technically, a monohull, however I look on the term as a subclass of the trimaran, different in that it has a much smaller percentage of overall buoyancy displacement in the outer hulls.
It neglects fundamental aspects such as the biomechanical efficincy of pedalling over rowing. Since the paper, like an optimisation, is just one position on one aspect of the science that is being studied.
I'm currently seeking ways in which to do the Pacific ocean crossing E-W but exploring the idea of having a multihull vessel as apossed to the normal single hull that you see most ocean rowers use.
This Hi-tech rowing boat is equipped with cooking materials and other working tools for you to use when rowing, and can eventually serve as your little home in the ocean, wherein you can also sleep with them comfortably.

Belic bought the plans for the boat inwards the other 1990s from Bolger a well known Belic had no ocean rowing experience but good for the journey away rowing ocean rowing boats plans. Our team of skilled artisans is responsible for delivering the best quality craftsmanship, paying particular attention to the smallest details. This and other custom range models are made from high quality materials which coupled with the premier craftsmanship creates exceptional ship model pieces.
Frank Samuelson and George Harbo were the first rowers to cross the Atlantic Ocean when starting from New York and heading towards the British Isles of Scilly in 1896.
We aim to cross the world?s largest ocean with a crew of eight people from mainland to mainland, Peru to the east coast of Australia. I have been searching (with limited success) for parametric vessel types to start my concept models, and wondered if anyone had any experience or interest in either ocean rowing as a sport, or in the iLAN type? However, the race is now on in certain quarters to innovate and improve on what we have so far. When I say Ocean Rowing Boat, I mean Atlantic, Indian, potentially Pacific, to be used in record attempts with a substantial number of crew. These hull forms were developed after the WWII with the intention of reducing vertical accelerations and resistance for Frigates etc, from operational experince. Lets say you decide upon a certain configuration of hull and decide to be made from some exotic material, as opposed to normal glass, for weight reduction.
Since It is not rocket science, the longer and more slender and the less displacement for the length is better than anything else. Otherwise the research becomes very time consuming and cost prohibitive for very little real gain. My issue is the thought of capsize in a multihull vessel and not having the ability to turn it back over as easyily as a single hull which tends to do it automatically. When you want to sail, using this hi-tech rowboat can also be of use, because it can also accommodate loads of equipments that you need or want to bring along with you when sailing. Inwards 1995 gravy boat fashion designer Phillip Chloe Anthony Wofford created plans for a boat ideally suited for rowing across Oceans.
It is capacious enough to shelter ii people and I am looking at for type A imitate of an ocean rowing boat programme or looking to steal a second hand ocean rowing boat. The first Atlantic rowing race as we know it today was launched in 1997 by Chay Blyth which made ocean rowing a mainstream sport. I am particularly concerned with low resistance hull forms at low speeds - a combination that doesn't often get addressed. Since Mondiale's demise, I would imagine there are a few interested parties in designing to beat the records she set.
This unaccompanied ocean rowing gravy boat was designed away Phil for Dave Clarke who wanted angstrom unit smaller lightweight and compress vessel to row across the mid Atlantic and the gravy boat ALL.
The AOR has too recently been supplied with the plans for a composite ocean rowing boat Phil Jim Morrison 2003. Ocean rowing boats as used in the races are divided into several sizes, in particular singles, doubles or fours and can hold between 1-14 passengers. I agree with your comments about windage though, which is tricky to achieve with a rowing hull.
