What Main Boats should look like

I simple took a screenshot and edited the sail of the ship. of course it has that pattern to fit all sides aswell.
Those plain white sails bore me xD

Meh. Seems sort of pointless since they already have their own colors, and there's really no problem.

Is that big secret thing that's coming out soon? *please be so!*

It should be a combination of simple techniques that come together to form something great.
