Four major differences between the units... First, the 4210 has NMEA 2000, the 3210 does not. Second, the 4210 has higher resolution, 800 x600 vs. 640 x480. Third, the 3210 has fewer soft keys, five running along the bottom of the screen, where the 4210 has eight of them along the right edge of the screen... Fourth, the 4210 can do autorouting for an autopilot... but I doubt this is all that useful on a sailboat.
Remember, either will take NMEA depth data off your existing depthsounder, if it outputs NMEA 0183....so unless you need a fish finder, that doesn't matter too much.
Also, the Weather XM service requires you to pay a subscription fee, and has coverage limited to mainly north america and the caribbean.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
