Here is a short video of the just completed regular Laser Worlds at the same site (they call this the Senior Championship).

Addendum: For those who don't bother to check the comments, the eminent blogger Tillerman has ran with my question on early Tech dinghy history and, through diligent research and his knowledgeable readership, has put together a very thorough tracking of the current whereabouts of the wood Tech dinghies. here.
Also, one of Tillerman's readers, O Docker, has pointed out the existence of a very fascinating video of the early days of MIT and collegiate sailing. Narrated by Hatch Brown, MIT sailing master in the early days, this video is for anyone with a love of sailing history. Watch the full 35 minutes.

The last photo was taken by me in about 1960 on the Port River. A couple of Rainbow scows and Cadet junior dinghys feature. The old steamship is the S S Karatta which carried freight and day passengers from Port Adelaide to Kingscote, Kangaroo Island from 1907 to 1961. It was then replaced with a roll on roll off ferry.
Here is my commentary:
1. Finn GBR 41 sailing dead downwind - or nearly so - in surfing and planing conditions (Judges so state after the yellow flag at ~ 45 seconds into video).
2. There is some rocking of the boat, apparently induced by the skipper. Since the boat appears to be changing course - to windward when heeled to leeward and vice versa - when this is done, the boat does not break any rule. See RRS 42.3(a) (and ISAF Interpretation Rock 6) which permits the boat to be heeled to facilitate steering. This is an exception to the prohibition on rocking found in RRS 42.2(b)(1).
3. The judges are focusing on the skipper's actions with respect to the sail - specifically pumping. According to the ISAF Interpretations of Terms Used, a pump is a single pull [usually vigorous] on a sail unrelated to wind or waves. RRS 42.2 (a) prohibits repeated fanning of any sail by pulling in and releasing the sail. See Interpretations Pump 1 and Pump 2.
4. RRS 42.3(b) permits one pump - but only one - for the purpose of initiating surfing or planing. One judge can be heard counting the number of pumps [at least two, possibly three] on the same wave. This breaks RRS 42.2(a). In addition, since the boat is already surfing or planing, the exception in RRS 42.3(c) is not available but, if it were, only the first pump would be permitted.
The ISAF Interpretation of RRS 42 may be found here http://www.sailing.org/2004.php They are dated 2005 but did not change for the 2009 - 2012 period.
