Toba is a popular tourist desnaon at the southern entrance to Ise Bay. Toba’s greatest claim to fame is as the birthplace of cultured pearls. The area is rich in lobsters, fish, and other seafood off the Rias Coast of the Shi‐ ma Peninsula.

Please email Kathryn at BE BACK ON THE WATER [email protected] or Elizabeth at [email protected] A message from Martin Morgans, Vice Commodore, sent before he set off on the first post-lockdown cruise. As, at the very least, a hint of normality has returned to our lives it is great to see that at last sailing has returned to the Royal Temple Yacht Club. The Cruisers have taken some small steps with a few ad-hoc run outs, with two weeks in Holland only days away followed by the East Coast and France. The racers are out all be it double handed, but they are out, with three races already completed. Six handed racing begins shortly. And lastly the RC Laser racing has returned to the club with new vigour and fresh faces. Saturdays at the Royal Harbour is fast becoming a tourist attraction thanks to the high-spirited competition which, after only four outings, has all the commitment of Formula One! The bar has taken its first tentative steps in the process of returning to normality with limited weekend opening 12.30 until 4.30pm. As the new chair of the Bar Committee I ask you to support the bar more than ever before. The current limited opening will increase to 250 CLUB DRAW RESULTS SO FAR reflect the need for it, the goal being to return February 2020 to normal opening hours just as soon as you, £25 No 12 Mr R Formison o the members, indicate by your attendance that £50 N 149 Mr J Williams £100 No 124 Mr C Richardson it is justified. -

How Fast Can a Sailboat Go?
How Fast Can a Sailboat Go? Alan Kruppa 1 Introduction Race, a no-rules, no-limits, round-the-world sailboat race set to begin on December 31, 2000 [1]. At the 65+ knot speeds achieved by modern high-speed sailboats, the hydrodynamic efficiencies of hull ele- ments play the dominant role in top speed performance yet the combined aerodynamic efficiencies of sail and superstructure elements begin to play an increasingly balanced role. It becomes necessary, therefore, to opti- mize high-speed sailboats for supercavitation hydrody- namically and low parasitic drag aerodynamically. A new design with a patented sail and hull configuration is introduced and shown here to have the best combi- nation of aerodynamic and hydrodynamic efficiencies, maximizing the theoretical boat speed to wind speed ratio achievable when looked at in the context of the Beta Theorem. From this section onward, a bold-italics convention is used to build the roadmap connecting the theory to the design. New concepts are introduced in bold and then summarized in numbered statements in ital- ics, which are the essence of the roadmap. 0.

A Short History of Timing
A SHORT HISTORY Contact details: WSSRC OF TIMING PO Box 2 Bordon Hampshire GU35 9JX 40 years of the World Sailing UK Speed Record Council Email: [email protected] PPL Media © IDEC - Francis Joyon (France). Single-handed Around the World Record Holder Cover picture: l’Hydroptère - World Nautical Mile Record Holder, Crossing San Francisco Bay. Alcatraz Island to leeward. Photo: © Christophe Launay INTRODUCTION The integrity of WSSRC has always depended on the skill and hard work of its Commissioners – men and women who seem to spend an inordinate amount of time standing on windswept shores or in icy water while strange sailing craft flash pass. One who has been involved since the very beginning is Michael Ellison who has quite literally spent years of his life ensuring that the right competitor gets the right time and that it is an accurate one. Here’s how he recalls it: Time? A frightening thought - I spent over a year on Fuerteventura alone ! The start was two weeks in Australia for Yellow Pages. A month in California for Longshot, a month or six weeks in Namibia for kites and then Sailrocket each year since 2006 Luderitz only has a small airport, a sign on the gate says “Please hand your guns to a member of staff before boarding the plane”. Usually I am driven from Cape Town or last year from Johannesburg by a competitor. It normally takes over 24 hours flying time to South Africa via the Gulf or via Frankfurt to Windhoek. Two weeks in Tonga (2004) and two weeks in Cape Verde islands clocked up some flying hours plus the driving time down to the numerous early “annual” French events, totting up several months in total at Ste Marie, Fos, Port St Louis, Leucate, etc. -

The main objective is to address the following questions: Is the long run sustainability of today’s well‐functioning network dependent on that existing airlines maintain their position in the Norwegian market? How can other airlines be expected to enter the Norwegian market if one or more of the incumbents reduces their level of service, be it from financial or other reasons? Will the structure of airlines or airline ownership have an influence on the level of service that is offered to the market? How will policy framework conditions and the current economic situation (influencing e.g. air transport demand and the level of competition in the airline industry) affect the supply of air transport services? The findings indicate that there are challenges in Norwegian air transport, connected to the weak financial state of affairs for SAS, Norwegian’s expansion plans with a unit fleet of larger aircraft and a network of 800 metre local airports with a limited number of competitors for the PSO routes and scarce aircraft availability. -
