L’Atlantico, ad energia solare e senza pilota…

I suoi creatori si chiamanoย Isaac Penny eย Christopher Sam Soon e ci hanno lavorato per quattro anni, prima del varo a Gloucesterย inย Massachusetts il primo giugno. L’idea era quella di realizzare il primoย mezzo autonomo e a propulsione solare che attraversasse l’Oceano Atlantico.

Il Sea Voyagerย รจ lungoย quattro metri ed รจ equipaggiato con 240 Watts di pannelli solari capaci di produrre 7 kWh al giorno in estate e 3 in inverno. Quasi tutta la potenza รจ utilizzata per la propulsione, il resto per gestire l’elettronica. Il tempo previsto per la traversata, contando su questaย quantitร ย di energia, รจ di circa quattro mesi con una velocitร  di circa 2 nodi.ย La barca รจ stata progettata e costruita con sistema modulare piuttosto complesso in modo da garantire, in caso di guasto di un elemento, l’intervento di un modulo gemello “di rispetto”.

Il peso non รจ poco, 250 kg, ma รจ dovuto ad una costruzione robusta in alluminio che assicuraย una buona resilienza,ย eย all’esigenza di creare una certa inerzia che garantisca una maggiore stabilitร  di rotta in oceano. Ha al suo interno due compartimenti stagni che ne garantiscono l’inaffondabilitร . ย Originariamente il progetto prevedeva la realizzazione di una canoa pneumatica, ma proprio queste considerazioni hanno fatto virare verso l’alluminio.

Se si vuoleย tenere sempre sotto controllo la posizione del Sea Voyager, collegata al sistema satellitare Iridium,ย bastaย dare un’occhiataย alla mappa aggiornata in tempo reale. Per il momento naviga regolarmente verso Est sullo stesso parallelo di Gloucester, ed รจ arrivata all’altezza della longitudine di Halifax, nella Nuova Scozia. Obiettivo raggiungere le coste del Portogallo per la fine di settembre.

Do you need to sell your boat? You are in the right place! yachtdigest.com is in fact the largest online portal on recreational boating and in this section you will be able to write your ad for free if you want to sell your boat. Adding a new sales message is very simple and intuitive as is finding a boat you are interested in buying, but to make your listing even more appealing, we want to give you some general but important pointers that you can follow if you wish.

First of all, try to personalize your ad, describing the history of the boat and perhaps the reason why you are selling it, this way you will gain more trust from the reader.

You can call it “half-new” if it is almost new, or “used” by specifying whether or not it is in good condition. It indicates the condition of the engines, the year of registration, how many owners it has had-most importantly, it indicates whether the boat has been owned by a single owner: it increases interest to those reading the ad.

The goodness of your craft must shine through in your message, because before you can convince someone, you yourself must be convinced that the product is good.

It is important that no spelling errors are made in the advertisement, so reread the message well before putting it online. The language then must be clear and simple, understandable to all.

It serves to attract interest and induce the reader to continue reading; it is the most important part and should summarize in one line the whole message we want to give. Unfortunately, you don’t have much chance to stand out much except with something really original to attract attention. So focus on truly original details of the boat, its real qualities: in the yachtdigest.com portal this brief summary will appear by hovering over the picture of the boat with the mouse.

It is important to clearly include the general record of the vessel. Always enter: shipyard, model, length, width, draft, engines, number of cabins, year of construction, price.

In the boat sheet accurately enter all boat details, standard and extra equipment. It is useful to communicate many details and details for those who are really interested and will continue reading beyond the first few lines.

Suggest to the reader who wants to buy the best features of your craft, and do not indicate-unless it is necessary to inform the buyer in advance-information that might negatively influence the reader.

Always indicate the price. Unless you absolutely do not want to deal, we recommend adding the words “price negotiable” which gives an incentive for the buyer to contact you.
