All of the following are Class Features of the Master Mariner prestige class.

Weapon and Armor Proficiency: A Master Mariner is proficient with all simple weapons, light armor, medium armor, but not shields.
Sea Legs (Ex): At 1st level, the Master Mariner has become accustomed to the pitch and roll of a ship at sea. She is never subject to penalties to the use of her skills due to the motion of a ship. In addition her familiarity with the shipboard environment confers +1 to AC when aboard a moving vessel. This bonus increases to +2 at 3rd level, +3 at 5th level, +4 at 7th level and +5 at 9th level.
Navigation (Ex): At 1st level, the Master Mariner gains +1 to Survival, Knowledge (Nature) and Knowledge (Geography) checks pertaining to the sea. When the Master Mariner can see the clear sky, at night or day, he can always determination his orientation, and will never misjudge the direction of true north.
Shipboard Climbing (Ex): At 2nd level, the Master Mariner gains a +2 bonus to all Climb and Jump checks when made aboard ship. This applies to scaling the outer hull of a vessel, and jumping from vessel to vessel, as well as climbing the rigging.
Lookout (Ex): At 2nd level, the Master Mariner gains a +2 bonus to all Spot checks for identifying hazards to navigation, such as reefs, pirates, islands and the like. This bonus only applies when in a suitable lookout position aboard ship.
Patois (Ex): By 3rd level, the Master Mariner has been exposed to a wide variety of languages. She can communicate sufficiently on a basic level to convey simple concepts and barter for goods in any language she could conceivably have learnt in her travels. This communication is limited to simple one or two word phrases.
Bonus Language (Ex): At 3rd,, 6th, and 9th levels, the Master Mariner gains an additional bonus language. This must be a language the Master Mariner would have frequently been exposed to in his travels.
Seamanship (Ex): At 4th level, the Master Mariner has become so familiar with the ways of the seas that she gains a +1 to all appropriate skills when used at sea. This bonus increases to +2 at 7th level.
Sea Sense (Ex): At 4th level, the Master Mariner has learned to observe subtle changes in the sea and sky that enable him to sense the approach of dangers at sea, such as pirates, storms, reefs and so on. On a successful DC20 Profession (sailor) check, the Master Mariner becomes aware that danger at sea is nearby. On a DC25 Profession (sailor check) he is able to identify the nature of the danger, and what must be done to avoid it.
Lore of the Seas (Ex): By 5th level, the Master Mariner has spent so much time swapping stories with other mariners that she has gained a body of knowledge about the sea and its legends. This allows her to make a check equivalent to a Bardic Knowledge check relating to anything to do with the sea. Levels in Bard stack with levels in Master Mariner for the purposes of this check.
Friend in Every Port (Ex): By 6th level, the Master Mariner is so well travelled that he has literally a friend in every known port. He can add +2 to Gather Information checks with regard to finding cargoes and other goods or services in known ports.
Cargo Mastery (Ex): By 7th level, the Master Mariner has learned much of the art of buying and selling cargo. He may add +2 to appraise checks with respect to cargoes.
Dead Reckoning (Ex): At 8th level, the Master Mariner has learned to calculate accurately the position of her vessel at sea. With a successful Survival check at DC20 + days out of port, he can plot the ship's course from the last port to the ship's current position.
Sea Tracking (Ex): At 9th level, the Master Mariner has learned the subtle signs of passage so that he can actually follow the trail of another ship at sea, even when it is out of sight. This ability requires a successful DC 30 tracking check.
Master Navigator (Ex): At 10th level, the Master Mariner has so mastered the art of navigation that she may confidently sail into unknown waters and bring home maps of newly discovered regions. She does so at half her usual speed, whereas a captain without this skill may only sail such waters at quarter speed and never routinely.
