The Mesa2 is the most suitable on deck solution for yacht racing for daylight view-ability, form factor, battery life and ruggedness. Additionally the touch screen works beautifully when wet - compared to iPads or other tablets which are rendered unusable with a splash of water.

Being a Windows tablet, Expedition runs perfectly on this machine and with the growth of wireless protocols to instrument systems this can be the only PC you require on board. I personally race very often with with B&G H5000 systems and a Ubunt Bullet M2 wireless device (or GoFree). I can connect Expedition directly to the H5000 processor 'websocket' and have full high speed 2 way comms - removing the need for a 'downstairs' laptop or PC.
