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...

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 ;-)

Iceland to the Falklands 2026

Welcome to an all-new route, the first of three Round the 'Old World' of Europe, Africa, Australia and Asia. To give each leg of the ROW a bit of length we'll try to hug the coasts as little as possible, so starting in Iceland our first leg of the series, which will also be the final leg of our Quarter 1 Ocean Championships takes us 7200nm to the Falklands, the full length of the Atlantic end to end. To make sure we'll get it done within the month we'll be sailing our Maxi Trimaran.

SSANZ Round North Island Race 2026 - Leg 1

Welcome to Leg One of the Round North Island Series in partnership with SSANZ. The four-leg circuit of New Zealand’s North Island is a true test of short-handed skill, and it begins with the 150nm passage from Auckland to Mangonui. This year, our SOLers will be racing the dynamic Sun Fast 3600 – Jeanneau’s renowned racer-cruiser and a proven flyer downwind. A gentle opener on paper… but coastal tactics and shifting breezes will demand focus from the start!

New Ice Age 2026 - Browerville to Longyearbyen


Our 2026 long-distance ice-boating challenge continues with a second race in Arctic waters, now from Browerville, where we arrived less than a month ago, continuing east, back to Svalbard’s Longyearbyen, leaving Canada’s Ellesmere Island to port and Denmark’s Greenland to starboard. It’s about 2500nm, which, if there’s wind at all, should, well-wrapped in your DN-cockpits, not take you more than a day or three, thus to complete your first (of several) online circumnavigation of the planet of 2026!

Beketov by Balloon 2026 - In Siberia


Way-back-when France and England, and Spain as well, were squabbling about who should control what of North America, only to lose the most of it to their own insurging colonists, their eastern European neighbour empire, Russia, was quietly assimilating vast, thinly nomadically populated territory of its own – Siberia! Amongst the many explorers and adventurers that served Russia so well in these conquests was the Cossack hetman Pyotr Beketov. Let’s pretend we’re he and eschewing horseback, let’s travel by balloon from Yekaterinberg to Krasnoyarsk – just a short 2000km (1100nm) section of the Trans-Siberian Express’ 9289km!
