That should work, but be aware that the top two slots should be used for a 30A breaker that cuts off AC for the whole boat. I have a panel almost identical to that and the third breaker is used for the few outlets I have aboard. It is a fairly limited system, but I have fairly limited AC needs on my boat.
I would highly recommend you get a charger like
this for use on your boat. To use it, merely plug it in... unplug it when you don't need it. However, it would be better if you have space on your boat for a larger AC panel, to get one and get a charger like
this, and
rig it to a fourth breaker, leaving the third breaker for the AC outlets.

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.
