New system for 34' sailboat

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum fferraz,

While Raymarine's MFD's are designed to meet the IPX6 standard for protection against water ingress, touchscreen performance may be adversely impacted when operating the MFD. For this reason, Raymarine's e-Series and eS-Series MFDs feature HybridTouch interfaces, permitting buttons and a UniController to be used instead of the MFD's touchscreen when operating in wet conditions. As such, it would be recommended that an a-Series MFD be accessorized with a RMK-9 Remote Keyboard when such MFDs will be operated in wet conditions. Should an a78 be purchased, then it would be recommended that a compatible thru-hull transducer be used for sailboat applications. Otherwise, your suggestion for the a78 and i70 System Pack would be a good recommendation. The E70203 a78 MFD does not feature charts, permitting a Navionics or C-Map chart card to be separately purchased for use with the MFD. The E70203 a78 MFD's package also includes no transducer.
