Thanks for the ranking. Feedback is really important, and if there are any subtle (or not so subtle) changes you would like to see ... color, font variations etc. ... I will be happy to work with you to give you the perfect logo you were hoping for.
#48 a little more fine tuning. I will be happy to work with you to make any variations you would like to see. I hope you like the design that says you are #1 in competence on air, land or sea.
