[edit] Sailing innovations

Page numbers below refer to: Yacht Racing The Aerodynamics of Sails and Racing Tactics. First published in English 1928, Fifth edition 1948. (Original German, also published in French and Turkish).

Inventions or developments include:

1. Wind-tunnel testing of sail shapes, aspect ratio, curvature, twist, jib overlap.
2. Telltales on sails (he used "down") (p19)
3. Bent boom (p80)
4. Bent topmast (p75)
5. sleeved mast or wing mast (p75)
6. cam cleat = curryklemme (German technical term, I suggest showing his original product, photo in the book)
7. fully battened mainsail, on 22sq m Aera 1922 (p64)
8. Aero (restored: see http://www.bluegreenpictures.com/perl/Cyan.pl?mode=lightbox&lightbox=68&offset=0 )
9. hull streamlining
10. These boats appear to be capable of planing on a broad reach and presumably did so, in spite of the absence of toe straps and absence of mention of planing in the text.
11. Is restored Aero capable of planing when sailed in the original manner (less toestraps, trapeze, etc)? In the UK, invention of planing dinghy is generally credited to Uffa Fox (Avenger) 1928. http://www.international14.org/index.php?option=com_content&task=view&id=29&Itemid=29
12. overlapping (Genoa) jib (p67)
13. Narrow jib sheeting angles and venturi effect
14. Spinnaker airflow
15. centreboard and rudder foil sections flat, arched, streamlined
16. analysis of wind shifts and weather patterns

and many other topics. GilesW 23:38, 30 July 2007 (UTC)

Since a regatta is an occasional event involving several races, I suggest that "1400 regattas" is impossible and should read "1400 sailing races" or "1400 dinghy and yacht races" or something like that. Any objections to this change? GilesW 20:02, 2 August 2007 (UTC)

More biographical details and dates please. GilesW 01:49, 1 September 2007 (UTC)
