My partner & I like all of the logos you submitted. We think the anchor shows security. There is an element that might show protection, that being a trident (like King Neptune's trident). Using this element might also add the color yellow in the background. Could you play with this idea?
We would like to see #70 with the anchor a touch slimmer, since it's outlined in gold, and change the background hole atop the anchor to blue from red. We would like to see #74 with the anchor a touch slimmer and the shield with a red border separated from the blue by white.
Designs 82 & 83 in our minds are both winners. We would like to see a version of each with the anchor without the gold border. Also, could you experiment with a couple of other fonts?
The trident in 82 runs into the shield border. Can you end the tridents at the bottom as in 83?
I'm not sure how to explain this. #97 & #98 are what we are looking for, except the tridents need to be stand alone elements and not run into the border of the shield. You did this correctly in #83. Notice in #83 how the trident does not touch the border. That's what we want.
Change the color just inside the shield border from yellow to white Reverse the colors in the lettering (change "American" to red and "Yacht Security" to blue)
