I started reading it because of the similarities with Grand Blue and I have to say that so far the humour has been solid and the art style really good.
The characters are enjoyable and the story is quite simple and straightforward, so if you're into deep and complex stories it's probably not the series for you
I definitely recommend you give it a try, especially if your into ecchi comedies and if you enjoyed Grand Blue I think you'll truly enjoy this series especially because some of the elements are also heavily used.
Overall quite entertaining and a good comedy.
