If you can get hold of a book called "High Performance Sailing" by Frank Bethewaite, there are a few dinghy polars in there - including a very detailed one for a Tasar, which I would imagine is roughly similar in performance - and take some numbers of the pics.

Actually this book is worth its weight in gold to the serious dinghy racer - it has many small contributions on trim an technique from various class World Champions and IIRC there are more than a few by the then Laser2 WC - Mendelblatt or something?
I will hunt down my copy and have a look for you also - whatever I find I can scan and post here...
I help develop the client interface for the best online ocean racing sim there is... __/)/)_/)__

Nice Stu - how did you make the graph? Manually entered data from the pic in the book?

Just loaded a scan in a 2-D CAD application and copied manually the graphs. I am learning better with visual methods ;-)

Current Races:

Christmas to Christmas Island 2025

Two waypoints, start and finish, and between them 5827 NM of two oceans. Not much time if we want to sit at the Christmas Eve table. You will need to maintain an average speed of over 10 knots, maybe quite possible with this Maxi Trimaran, but prepare your vessel well and choose the best of the many possible routes. Hands up everyone who knew there were TWO Christmas Islands?! OK, maybe you have sailed this Sailonline course before... but it's time to get ready for the 2025 challenge of racing between Christmas Island in the Pacific to Christmas Island in the Indian Ocean! It also marks the conclusion of our prestigious Ocean Race Championship 2025. Please have fun! Fair winds!

Andaman Islands PYOC 2025


The Andaman Islands are an archipelago, made up of 200 islands, in the northeastern Indian Ocean. Together with the Nicobar Islands to their south, the Andamans serve as a maritime boundary between the Bay of Bengal to the west and the Andaman Sea to the east. These waters will be the theater of our next 240nm race in the ARCH 2025 series. Which one you choose depends only on you, i.e. your Elan 410 sport will leave the Andaman Islands on the starboard or port side.

Sinbad by Balloon 2025 - Carnarvon to Dondra


From here, our home in Bharatavarṣa is now north west of us – said Sinbad to his fellow balloonists. Perhaps we can ride the wind first further north, and then catch the winds that every year bring the rain, perhaps not. It’s 2600nm and we could be aloft awhile, so, Master el-Quarters, victuals only, no sandbags, provisioning the giant hamper. It will be not a picnic!
