Fantasy civilization

Okay, so in this magical fantastic world I'm creating, there is one civilization that I invented to flesh out the universe a bit. I can't think of a name for it now, but they're kind of trickster-like and slightly supernatural, so I'll call them Fey for now.

The Fey live a nomadic lifestyle, following the currents of the seas and the migrations of fish and birds, only stopping by the land to trade. They live in colonies of approximately 30-50 people in gigantic longboats. All the chores, which include building, tying, fishing, cooking, storing, and caring for young ones, are shared equally among the colony members. At sea, the Fey mostly eat fish and the meat of other aquatic creatures. When in shallower waters, they also collect sea vegetables, and shellfish. Citrus fruit are extremely prized among the Fey, because they ferment it into a drink that is consumed during sacred and special occasions, as well as being a source of much of their vitamin C.

Despite being disorganized as a whole and having no land to call their own, Fey civilization is actually made up of many (warring) monarchies, called clans. Today, there are 15 main clans. Some of these clans have split apart and declared independence from their mother clans. This has happened so many times that the true number of clans that consider themselves independent may be impossible to know for certain. (Some clans recognize the legitimacy of a few newly independent clans that have gained power, but not always.) Each clan is made up of many longboat colonies. They may split apart or come back together as they please, or to band together against a common foe. Each longboat is led by a captain, a man or woman who is the child of the previous leader of the colony. Other children might stay with the captain, or go to found their own colonies of the clan. (The latter option is a perfectly acceptable means of revolt within the Fey, and is not a cause for war.) Extremely discontented or power-hungry children will either assassinate their siblings, or mutiny and form their own clan altogether.

Fey people are short, and rarely grow higher than five feet tall. The majority have olive skin, and eye colors that range from deep chocolate brown to nearly yellow. Their hair ranges from black to dark brown to auburn, but premature graying is also common and it is not unusual to see a Fey person with several gray streaks in their hair by their early 20s. Because of their active lifestyle of doing the chores on the boat, all Fey are muscular and lean in build. (According to superstition, obesity is considered to be a sign of a greedy personality.) Their clothing is generally loose and baggy, and they are able to fit many layers of fur underneath to keep warm during cold weather. Most Fey people put their hair in braids, which are then woven with cloth into ornate designs. Others put their hair into one or two braids and cover the rest of their hair. The color of the clothing of a Fey person indicates their colony and clan affiliation.

A Fey boat is an interesting construct, for it is literally alive. It is unclear to outsiders how exactly a Fey boat is created, but it is believed to be something like the process used to create a homunculus or golem. However, unlike a homunculus or golem, these boats are capable of growing, self-healing, and shifting shape to reduce drag. Fey boats are intelligent enough to understand commands, but very few can really be considered "sentient". They are simply an extension of the will of the inhabitants of the boat. The prow of the boat is adorned with the clan's namesake. The stern of the boat may have a tail on the end, and some boats even have flippers or (non-functional) legs.

A special kind of Fey boat is the Wedding Barge, and it is a tradition as old as the Fey themselves. When men and women come of age (about 16 or so), they are brought to the Wedding Barge. There, they interact with the other visitors of the barge until they find a soulmate, at which point the head priestess (the only permanent resident) marries the two. (Homosexual relations are not frowned upon among the Fey - they are usually given the role of caregivers while the actual parents do chores.)

I'm still world-building for these guys, but suggestions are greatly appreciated. Thanks!

I can't really offer any direct suggestions. But if you could try get inside their heads and find out how they think and then apply it you'll get all sorts of really wierd stuff that still is internally consistent.

Best thing I find to do is take a trait of theirs, eg, their view on obesity. Why do they think that? I guess they believe that your outward appearance reflects your inward personality. What implications does this have? Maybe they might view other physical deformities as having special significance. eg, if your ugly you have an ugly personality. Though maybe you only would want them to view the outward characteristics that are not genetic as significant.

Another one, though it may just be cause you haven't mentioned it, is the lack of land. It seems that trading is the only reason to go on land. So what keeps them from land? Is it biological, societal, or spiritual? What are their religous beliefs?

@Gvzbgul - Thanks, I'll work on adding that now.
