How do I buy charts for the Caribbean to use on my coastal explorer?
Just noticed you also asked here, so you’ll get your answer in the reply to your email too.
For that area you will need C-MAP charts. Here’s a video on how to purchase and install them. Make sure you pick the region that works best for your future cruising plans. There are three regions that include Antigua:
M-NA-M027 - CENTRAL AMERICA AND CARIBBEAN
M-NA-M035 - PACIFIC COAST AND CENTRAL AMERICA
M-NA-M033 - ATL. COAST, GULF OF MEXICO & CARIBBEAN
