I'm writing a story that takes place on an island. This is an earth-like planet in gravity (though I'm willing to negotiate this one a little), climate, etc., but it's almost completely covered with shallow oceans.
What I'm curious to know is what features of the planet (since I can adapt it as needed) would make it easier or harder to maneuver a small boat? (think, something a somewhat primitive tribe could make that's designed for two people. EDIT: The two-person boats are built for speed, not range. There might be other boats for going longer distances.)
Tides can definitely be manipulated, I'm planning to have two moons and their sizes are definitely open for negotiation at the moment. If that helps, go for it. Do note, they're co-orbital in a similar style to Saturn's Janus and Epimetheus, so they have to be the same distance from the planet; just manipulate size/mass and what that distance is.
So, in short, how can I manipulate tides (i.e. moon size), weather, gravity, topography, currents, or any other feature of the planet to be maximally conducive to boating but still keeping the planet reasonably habitable by humans?
