For the real "otaku's", I'll say: Both have ecchi.
For people who actually care about the shows and not just animated boobs.
Although Umisho deals with Ecchi overall, in Tonagura! they only deal with ecchi of one person point-of-view. The art does match quite a bit, but the story's are different on multiply levels. But then again, the art's pretty much the same, just like some characters are similar. The comedy are both of the same factor, and some situations are exactly the same.
