Re: opencpn Charts
Don't use outdated maps for navigation. The map of Spain including the Canarian Islands costs only 16.90 €. https://o-charts.org/shop/en/oesenc/15-es.html |

Re: Plotting Questions; Radar ranges; magnetic compass bearings; positions on Open CP
I have a radar, but it is not connected to OpenCPN. The jamming has been much further north than I live, so I have no first-hand experience. I believe that the other types of GNSS are less... |

Re: Spurious track points when merging

Re: Radar recommendation
Sailed 82 nm along the coast of Norway last night. Even if the visibility was good, radar was very helpful. I detected all boats on the radar before I could see them. Only about half of the boats... |

Re: Weather Routing
The reason i had set a high tacking time was that when sailing along the shore i need small timesteps i order to not get "stuck" in the islands. Then the I got routes with tack every 15 min, and that... |

Re: Weather Routing
I get a bit confused by my weather routing results. The boat speed is much higher than the one I specified in the polar. See the example below. This is a simple polar for motoring with max speed of 7... |
