QuoteOur vessel "Kingdom of Fife" is primarily engaged in a wide range of mooring and navigation buoy maintenance tasks. It has used the e-SEA™ system from Woodsons for some time now, and it has transformed our approach to shipboard communications. Benefiting from always on broadband without punitive data charges has allowed easy communications with the vessel and I am pleased to recommend it to others. Quote
