Bad weather for iNavX [Update]

What I've been planning for a while has finally happened. : iNavX lost Navionics mapping ! It seemed obvious that the historic contract which allowed iNavX to have privileged access to Navionics cartography, since the origin of the application designed by Richard Ray in 2009, was threatened. Since then things have changed a lot : repurchase of the application by NavX Studio (¹), acquisition of Navionics by Garmin (²), generalization of the annual chart subscription policy (³)… Read more …

Predict storms with Weather4D


In Weather4D (all versions) most weather models provide a data called CAPE.

Convective Available Potential Energy, in French : Energie potentielle de convection disponible. Behind this obscure acronym hides a powerful storm forecasting tool. CAPE is measured in Joules per kilogram of air (J/Kg) and defines the vertical buoyancy energy of a hot air particle in a colder atmosphere. In other words, vertical acceleration of the air particle will be directly related to this energy measurement. Read more …

Weather4D and iOS LAN

From iOS/iPadOS 14.5, A new setting has appeared proposing to allow applications to access the Local area network. This option is offered when installing a new application, but is not necessarily activated if the application is already installed when the OS is updated.

MacENC is back

MacENCx64 is now the name of the MacENC application which has just been published by its new developer NavStation.

MacENC has been completely adapted and recompiled into 64 bits for recent MacOS systems and new processors, which explains the new name. I continue to ensure the French translation. But be careful : to date Navionics cartography is no longer available. So there is no charting yet for the coasts of Europe, except ENC S-57 and S-63 available from Chartworld (see the page Digital charting). Read more …

While, this morning of the 9th day, Hugo Boss at the top of the Vendée Globe 2020 finishes crossing the “Doldrums” at a slow trot (¹), followed by the fleet of competitors which spread out behind him to the north of the Cape Verde Islands, It is a completely different score that the leaders of the game are playing Virtual Regatta.

Friday 13 November will not be a lucky day for the Vendée Globe skippers 2020 (¹). They will have to negotiate the encounter with tropical storm "Theta" which crosses their course with average winds that can reach the 40 nodes and powerful bursts. Above all, the sea will be to be feared because, strongly crossed as they passed the centre of the low pressure system, Waves may exceed 6 meters and break in a chaotic way. Read more …

Routing : from game to reality

On the second day of racing of this Vendée Globe 2020, we can say that the weather conditions that the skippers will experience on the descent towards the Doldrums will be particularly tough. After a departure in a damned weather, A first weak cold front passed without incident, The Solitaires will cross a second, much more violent front during the night and morning from Tuesday to Wednesday, for the group that went to the West, and in the evening for the group passed between the DST (¹) and Gallicia.

But these upcoming conditions are very different for Virtual Regatta players and For sailors… Read more …
