Welcome - Small world...I grew up in the Tampa Bay area myself...Up and down the gulf coast actually. I have submitted some ideas that show a simple elegance with a hint of geographical appeal.
My favorite is #40 where the sail seems to form an abstract JD.
Please feel free to offer any suggestions or feedback that you feel would be helpful.
I like # 38. Colors are good. The JD logo to the left of JD NOBLE needs some adjusting as it is hard to tell that it says JD, it looks predominantly like just a D. Also place the JD logo on top of the JD NOBLE. On your other designs I do not like the Blue wave visual you are using. Thanks and great work.
#38 - I like this one. Can you place the JD logo above jdnoble and Make the JD in the box easier to read. I'm losing the J when i look at it. Also some more color variations.
