It is nice if the boat has sails (in case of a sailing boat) and some form of aux propulsion
, oar, etc.).
I like dodgers and other forms of keeping excess of wind
, rain or sun away from the cockpit
. In cold areas some form of heating
is a plus (we use an electric
in), if the area is cold, dehumidifier is a great device.
I also like our dinghy
(inflatable) and our anchors (only if you need them).
Onboard get things you normally use - some like radios, others prefer computers
access, others like TVs, etc.
If you live onboard, cooking
facilities come handy. We use LPG two burner cooker with oven
. The oven
is a blessing.
You know, you are only limited by your imagination, budget
and the boat's volume ... ;-)
