before you people come with those argument about sun celestial gears etc,
maybe you should go with a basic map,
i mean us spherical earth beleiver, begin by the first step and did a basic map of the round earth, and we did explore all the place on it, refining it,
in your case you just omit the basic thing, started by explaning the edges, and your so called ice wall that repulse boat in a mysterious way,
explain also why there is no report what so ever of boat in the entire naval history that have go againts this so called magnetic field and couldt go any further
there is a lot to be explain before, the sun on the horizon, the celestial gears even your gravity with the stupid 94 meter second theory that we go upward,
anyway just my cup of tea onvce again you wil probably just ignore all of those cause this site is a joke
