When fishing on a sport boat, it is wise to dress in layers, and don water resistant clothing and boots.  Water resistant boots are usually overlooked by new fisherman but fishing with damp socks throughout the day can be very uncomfortable so be sure to look into purchasing some before your trip.  Wearing layers can help you adapt to the changing temperature from morning to night time. Staying dry and comfortable will ensure you spend more time at the rail fishing rather than avoiding the elements in the galley.
