Redmonke suggested that the skill should have a skillcape. I was thinking that it could include a picture of a cape, with the boat and OSRS gold sailor behind. The message could be: You try to get to get a mini-ship, and then begin sailing across the sea. It's a straightforward idea, but it would be quite funny. Girfaniam recommended Fishing Boats. I am now adding onto his suggestion.

It is possible to build a fishing boat at level 20. It will be a tiny wooden row boat. As your level gets higher the fishing boat can be expected to grow. Additionally, on your ship you can visit the port side and the PORT SIDE ONLY (Unless there are any weapon restrictions there) You will be able to fly fish or use a normal fishing rod. This would be a great experience to fishing. If you're running short of supplies for your crew, you can simply fish and then give that to them. You could also visit the nearest port.

As suggested by a number of people and as seen in other forums, this may be a journey. Here's my lame and made-up quest. Quest: My Sailor's Journey! The way to describe it is simple. Length: Medium. The requirements are good food, armor, and a fishing rod. You must be able to take on the level 200 Sea Serpent using only range, mage, cannons, or catapults. Must have complete Pirate's Treasure Quest.

Walkthrough: You have the option to start the A Sailor's Life! Find the biggest port in runescape - Port Sarim. Talk to Trader Stan for advice on how to build similar ships to his. You will be amazed at the custom-built ships he's built. When you ask him how, He says that you need to find items for him. Redbeard Frank's Priate Hook is the first item you'll need. Also, you will require a Jug of Wine, Karajama Rum 5k and an Asgarnian Ale. You will also need to find the peg leg.

Talk with Redbeard Frank, and ask for his hook. He will tell you that you have to arrange a date for him with Emily at the Rising Sun Tavern. Emily is crying in the tavern. You ask her why she's crying and she tells you that she's going to be forced to shut down the restaurant because she's not having enough customers. She states that she needs 5,000 GP to remain open. She says she would be cheap RuneScape gold open to a date with Redbeard Frank if she gave her 5k. Redbeard Frank will contact her and she will be able to pay the $5k. After that, he'll give you the hook.
