Reed's Digital Almanac : The Bible of anglophile yachtmen

For those who navigates in the English Channel and along British shores, an elementary English language practice is a great help. Except know order a « Pint of Guinness » or a plate of « Fishes and Chips » at the first pub landed, nautical books in English reading, with help of a French-English Navy terms lexicon is a valuable asset. English navigation guides are among the best in the world, to the extent that many of them have been translated into French, as Imray Guides.

But if there is one absolutely essential, It is the Reed's Nautical Almanac, « The» English Bible for boaters. A pad of several hundred pages, fortunately available today in digital version on iOS. (continue…)

Iridium GO! A positive feedback [Update]

Following my previous entries (¹) concerning this satellite communication device, I stayed wary on the interest of this product despite its indisputably innovative character, indisputable ergonomics, and an excellent quality/price ratio. Defects in youth who have taken a long time to be resolved, and especially a substantially lower data transfer rate (²) other brand devices (Iridium 9555 and 9575) had overshadowed for me the positive aspects, mainly concerning requests for GRIB weather files.
