LOGO DESIGN NEEDED

I would like to design a logo for my company: Shipshape Sailing. The company will offer sailing services (teaching, adventures, deliveries, etc.). There is of course therefore a marine / nautical theme. I would like a logo (perhaps with two different colour schemes) that can work well on both a dark and light background. I have attached a Powerpoint slide where I've collated all of the logos from companies in the same sector providing similar services. Most of the logos I like have a small sailing relevant emblem, that resembles a sailing boat, or a sail. My favourite of these is probably the very simple, single colour, emblem for blueoystersailing. Of the others, as an example, I also like the Tall Ships Youth Trust Logo, and how they have two separate font sizes (Tall Ships in larger font + YOUTH TRUST tucked in underneath in smaller font). I also like the mix of capitals and non-capitals. None of these ideas are intended to be prescriptive! I would like to work with a designer to come up with something really professional looking for the company. My intention is just to highlight some of the things I think I like or don't like about the logos of similar competitor companies in order to give you a guide / reasonable starting point! I would be happy to review and discuss some ideas or draft logos as part of an iterative process to develop the final logo.
