Guidance for Rowers and Canoeists on Shared Waters
Guidance for Rowers and Canoeists on shared water INTRODUCTION The growth in participation in water sports means that many rowing and canoe clubs and centres have to share the water where they row or canoe and it is important to build good relationships. This advice is published jointly by British Canoeing and British Rowing. Rowing boats and canoes behave very differently. By understanding these differences, and agreeing and following some basic guidelines, rowers and canoeists can happily share the same piece of water. The following table highlights the major differences: Rowing and sculling boats Canoes and Kayaks Relatively fast Relatively slow Good view astern, poor view ahead Good view ahead, poor view astern Not very manoeuvrable Manoeuvrability varies according to design Wide (up to 7 m blade tip to blade tip) Narrow Difficult to stop quickly Easier to stop quickly What canoeists need to know about rowing boats • There are many different types and sizes of rowing and sculling boats, for 1, 2, 4 or 8 people. • Rowing boats (especially 4s and 8s) are fast and go well in straight lines. • Rowing boats do not naturally stop quickly but rowers can do an emergency stop. • Rowers do not face the direction of travel. • Some rowing boats have coxes – some are in the front of the boat, some are at the back. • Coxes have restricted vision – the ones in the front cannot see behind at all or to the side very easily, coxes at the back have difficulty seeing directly ahead, can see to the side and have limited vision behind. -
Human Powered Hydrofoil Design & Analytic Wing Optimization
Human Powered Hydrofoil Design & Analytic Wing Optimization Andy Gunkler and Dr. C. Mark Archibald Grove City College Grove City, PA 16127 Email: [email protected] Abstract – Human powered hydrofoil watercraft can have marked performance advantages over displacement-hull craft, but pose significant engineering challenges. The focus of this hydrofoil independent research project was two-fold. First of all, a general vehicle configuration was developed. Secondly, a thorough optimization process was developed for designing lifting foils that are highly efficient over a wide range of speeds. Given a well-defined set of design specifications, such as vehicle weight and desired top speed, an optimal horizontal, non-surface- piercing wing can be engineered. Design variables include foil span, area, planform shape, and airfoil cross section. The optimization begins with analytical expressions of hydrodynamic characteristics such as lift, profile drag, induced drag, surface wave drag, and interference drag. Research of optimization processes developed in the past illuminated instances in which coefficients of lift and drag were assumed to be constant. These shortcuts, made presumably for the sake of simplicity, lead to grossly erroneous regions of calculated drag. The optimization process developed for this study more accurately computes profile drag forces by making use of a variable coefficient of drag which, was found to be a function of the characteristic Reynolds number, required coefficient of lift, and airfoil section. At the desired cruising speed, total drag is minimized while lift is maximized. Next, a strength and rigidity analysis of the foil eliminates designs for which the hydrodynamic parameters produce structurally unsound wings. Incorporating constraints on minimum takeoff speed and power required to stay foil-borne isolates a set of optimized design parameters. -

Paddle and Rowing Sports—Balance, Coordination, Etc
Physical Activity: PADDLING & ROWING SPORTS While participants are engaged in a paddling or rowing activity, they are getting lots of health benefits. The information in this packet details those benefits, from the muscles paddling and rowing sports develop to the way they make people feel. This packet supplements what you will be doing during paddling and rowing sports. You do have to get participants to recognize that these activities are great for their physical and emotional health, but you can do that in the way that best works for your group and you. These materials offer lots of different ideas for incorporating the health components into your already fabulously planned session. Read the Facilitator’s Guide in order to understand Frost Valley’s physical activity initiative, to effectively use the materials in your session and for ways encourage physical activity among your participants in and beyond Frost Valley.

Realistic Evaluation of Hull Performance for Rowing Shells, Canoes, and Kayaks in Unsteady flow
Journal of Sports Sciences, July 2011; 29(10): 1059–1069 Realistic evaluation of hull performance for rowing shells, canoes, and kayaks in unsteady flow ALEXANDER DAY1, IAN CAMPBELL2, DAVID CLELLAND1, LAWRENCE J. DOCTORS3, & JAKUB CICHOWICZ1 1Naval Architecture and Marine Engineering, Strathclyde University, Glasgow, UK, 2Wolfson Unit for Marine Technology and Industrial Aerodynamics, Southampton University, Southampton, UK and 3School of Mechanical and Manufacturing Engineering, The University of New South Wales, Sydney, NSW, Australia (Accepted 28 March 2011) Abstract In this study, we investigated the effect of hull dynamics in shallow water on the hydrodynamic performance of rowing shells as well as canoes and kayaks. An approach was developed to generate data in a towing tank using a test rig capable of reproducing realistic speed profiles. The impact of unsteady shallow-water effects on wave-making resistance was examined via experimental measurements on a benchmark hull. The data generated were used to explore the validity of a computational approach developed to predict unsteady shallow-water wave resistance. Comparison of measured and predicted results showed that the computational approach correctly predicted complex unsteady wave-resistance phenomena at low oscillation frequency and speed, but that total resistance was substantially under-predicted at moderate oscillation frequency and speed. It was postulated that this discrepancy arose from unsteady viscous effects. This was investigated via hot-film measurements for a full-scale single scull in unsteady flow in both towing-tank and field-trial conditions. Results suggested a strong link between acceleration and turbulence and demonstrated that the measured real-world viscous-flow behaviour could be successfully reproduced in the tank. -

Est., Ruddington Lane, Nottingham NG11 7HQ. Tel: 0115 945 5522 Fax: 0115 945 5533 email: [email protected] web site: www.concept2.co.uk ii Indoor Rowing Training Guide, version 2 Preface We are constantly being asked for training advice, be it for a 2,000m race, rehabilitation or general fitness. As every personal trainer or fitness expert will tell you, prescribing training is not that simple. Level of fitness, training background, maximum heart rate, history of illness, time available to train and your own expectations are just a few of the factors that need to be considered when starting any training programme. We developed the original Indoor Rowing Training Guide to address all these issues, and ultimately make sure you make the right training decisions. The Indoor Rowing Training Guide, version 2 has built on the success of the first Guide and now includes sections on Nutrition and Diet, Psychological Preparation and has input from many top rowers and coaches. The Indoor Rowing Training Guide, version 2 will help you whether you are training for a race or simply would like to achieve a more healthy lifestyle. Although we can’t anticipate every individual’s requirements we aim to provide information on the basic principles involved in designing training programmes and, by including many and varied examples, guide anyone in constructing an individual programme suited to their own personal needs. -
