2009-05-19 00:01:24 - weird lines in view screen
This is a problem that I started to notice in leg 5 and in leg 6. Now it has gotten much worse. In the two previous legs it usually showed up as an extension of the land in a wide green line across the screen. On occasion and now in this leg (especially away from land) It shows up as extensions of the course traces of my boat, the lead boat and any other boat selected in the boats tab.
As I zoom in and out the lines jump around and sometimes grow quite large. Zooming in and out definitely causes them to move around and change in width.
This is happening on two different machines, my Vista laptop and my XP desktop. In both FF3.10 and IE 8 on the Vista OS, and FF 3 and IE 7 on the XP OS.
I haven't heard anyone else mention this but it does seem to effect both of my computers, with different OS's and graphics hardware and programs. It is a bit annoying when I'm trying fine tune a course. Any Ideas??

Me too. It mainly happens on the higher magnifications.

Thanks guys for reporting this.

It is certainly more visable during this leg, we know that this bug is there but haven't had the time to work out and implement a fix for it.

We will try to resolve this one soon, Jeroen

Maybe is somehow related to fix for crossing dateline? It first appeared for me during the Leg from China to Rio.

Yes, all these graphic bugs were introduced when we implemented support for datum line crossing. The algorithms actually get a littly tricky when you have vector maps supporting seamsless rotation :) Both me and Jakob currently have a pretty high workload with both our day jobs and SOL and Sailplanner and other things in life - so even though we will fix this it might take a while.

SSANZ Round North Island Race 2026 - Leg 3

Leg Three of our Round North Island Series, in partnership with SSANZ, keeps the pressure on! From Cook Strait, the fleet turns north for a 187 nautical mile passage up the east coast to Napier. It may look like a quick overnighter, but shifting coastal winds and the ever-lively Cook Strait demand sharp focus. In our responsive Sun Fast 3600s, a proven short-handed racer and powerful downwind performer, tactical decisions and precise timing will make all the difference!

Dyer Dhow Derby 2026


Most winter weekends, SOLer wsguerin and his friends at the Mamaroneck Frostbite Association venture forth on Long Island Sound to race Dyer Dhows, originally designed as WWII tenders. Indestructible little boats, great comradeship and serious short sharp races of 10 to 20 minutes duration. Sailonline now invites you to experience the joys of the Dhow in winter, virtually, by way of a slightly longer 14nm race: from Mamaroneck to Execution Rocks, over to the Gong Buoy and back to Mamaroneck. And if the wind pipes up to 20kn and beyond, you'll find SOL's customized polar will plane, rather than nosedive!

South China Sea Race 2026


Welcome all to the South China Sea and a virtual chase in Cookson 50’s of the Rolex South China Sea fleet, racing 650nm – as the local red-footed booby flies – from Hong Kong to Subic Bay on the southern tip of The Philippines’ Luzon Island. Chances are it will be a fast downwind ride, so see how you can keep up with the real-life fleet which we hope to be able to follow on our monitors.

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.
