Gordo, etc
If you have the room, a built-in computer (like Argonaut with an Ocean PC {now Argonaut} screen) is the way to go. No problem with dropping it or getting it wet. Nobeltec is far superior to the others, stability has never been an issue, and the vector
charts are worth the price of entry.
Si-Tex isn''t much of a
radar compared to
Raymarine, but its the only one that permits
radar overlay with Nobeltec. The
Raymarine radar overlay with MARPA, etc. unfortunately only works with
Raymarine 4.0 & now 4.1 software, using seatalk (much faster than NEMA 0183). In talking with
Raymarine, no plans to interface with other people''s programs. Good luck.
