I am interested in obtaining a used dink this winter.Any ideas what size would be right? I would like an Inflatable (hypalon only) so that it can be easily stored.I have a family of 5 (me included) and want to take trips to shore from the anchored boat. We dont all have to go at once.Should it be towed or tied up out of the water on the stern?Also, what size motor would be best.I will have to lower it (the motor) from the stern to the dink so it should not be to heavy. Dont want the motor to be an anchor without a rode.
