Irresponsible Captain Tylor is a comedy. The main character, Tylor is the captain of a destroyer, THE SOYOKAZE, in the UPSF (United Planets Space Force), who is fighting the Raalgon Empire. He is the commander of characters such as: Yuriko Star - Lt. Commander, Yamomoto - First officer; a bunch of marines, 3 pilots (Kojiro, Emi, Yumi), and several others. Tylor is always doing extremely stupid of highly intelligent things (they never say if he's a genius or just an idiot). For example, he defeats entire Raalgon fleets with his single destroyer, just by "luck" as he calls it (others call it stupidity or ingenioustactics).

My interpretation is that Tylor is a genius. After all, he definitely seems to act wise in front of his crew, like saying things such as, "Don't live under someone else's rule; live life like you want to." Furthermore, he definitely seems to have exceptional plans in some episodes.
