Board » Technical Support » Big difference SOL map and Sailplanner

On SOL-map the SW point of Noronha is at -3.8778 and -32.4795.
If I make a waypoint in Sailplanner with this position it will be placed 1 NM north of Noronha! (I use the map "SP Atlantic South (GFS)")
Why?

There is also a difference with for example TWA when I sail the same CC at the same position and the same time! That makes Sailplanner difficult to use...
Differences in Maps are quite normal and do happen even in official Maps as a Result of Errors in Positiondetection by the original Measurer.

Did you use the latest SOL-Weather from Brainaids Toolbox (http://sol.brainaid.de/sailonline/toolbox/)?
If so there might only be small Differences due to different interpolation schemes.
How can you use brainaid's weather in Sailpanner?

Thanks!

You can't.
The dropdown list on the main toolbar contains the only weather systems you can use...
I help develop the client interface for the best online ocean racing sim there is... __/)/)_/)__
down loaded sail planner, for leg 2. and I'm registered in leg 2, but when I log in to sail planner, my boat doesn't appear??? I'm using the map for the indian ocean. ????
Sailplanner is not linked to sailonline in that way...

To get your boat or GPS location into SP automatically, you will need the NMEA proxy for the race from brainaid's toolbox, and a program called NavMonPC (very useful in its own right), to get the data from the NMEA proxy sent out on a virtual COM port, that SP can then read from.

Other than that, just drag the boat icon to match your current race location, or the start for pre-start routing, and go from there...

Red Eye 2026 - Georgian Bay

Welcome to the sensational scenic Georgian Bay of northern Lake Huron, the first area of the Great Lakes to be visited by Europeans in 1615, so former SOLer A2R informed us when he designed this geometrically tortuous course of 317nm criss-cross through its island maze. Originally known as Lake Manitoulin, in 1822 the bay was renamed after King George IV after his succession to the throne. This time we’ll take the very flashy Fareast 31R, which hopefully should keep you wide awake!

Welcome to the fourth of four virtual Tall Ships Races in European waters which are concurrently being organized in-real-life by Sail Training International .

Chinook Salmon - Canada to Andreanovs


A year after spawning in the upper reaches of the rivers of British Columbia, Chinook Salmon develop the age-old urge, so familiar to SOLers, to go to sea, heading for different parts of the northern Pacific Ocean. This race catches up with a particular school with an instinctive memory for the Andreanov Islands far west on the Aleutian Islands chain, as they depart the Salian Sea between Vancouver Island and the San Juans. It’s 2200nm and we’re taking the 60ft Trimaran, in the hope we can keep up!
