So I've been playing a lot of hamlet and shipwrecked recently and I'm surprised woodlegs hasn't already been added there's a lot of potential for him especially since a lot of players lack the motivation to even explore the ocean at all in dst. One of his perks would be to make his own ship. This is very much needed and would be more aerodynamic looking like a ship variant in the dst "more boat shapes" mod. Another would be his own craftable sail. This would have the power of three sails having one sail on the top and two on the sides having a pirate symbol on it. This would really help passing out the slog that is traveling the ocean in these clunky, and unintuitive boats, saving space as well as increasing speed. The downside of this is that it would not be able to have any attachments like the lightning rod attached to it. Another perk would be his ability to sing sea shanties. When woodlegs is sailing the ship he could start to sing sea shanties with everyone on the same boat as him. The sanity gain for this would be very slight, but would grow with the number of players singing. The last perk would be his lucky hat. Similar to shipwrecked his hat would increase the chance for him to get ruins tier equipment making it more convenient for him to get the chests instead of delving into the ruins.
One drawback to woodlegs would be his slower speed on land as well as his sanity drain on it. These two would make woodlegs more reliant on the sea. Another downside to him would he that he gains less stats from eating food that isnt sea food. Sea food isnt always very filling so one way to fix this would be to either add new fish recipes for hunger, or have woodlegs gain more hunger from seafood. That's all that I can think of I hope klei can consider my ideas I've presented.
