Hi, I am new to Wikipedia and I am not sure how to edit or add files, or to add a comment here other than editing what is already written. However I would like to point out that your file for flag "H" is incorrect, as it shows white and red split vertically. Flag Hotel is actually white OVER red split horizontally, this matches up with the International Regulations for Prevention of Collisions at Sea in which a pilot vessel shows two all round lights in a vertical line, the upper of which is white and the lower of which is red. It also gives birth to the simple phrase from distinguishing a pilot vessel: "White over red, pilot out of bed"
