"Once again thanks to your valuable advice & guidance we managed to dodge the Hurricane(s). Keep up the splendid job!! It was most re-assuring to know that someone was "with us" all the way and it is much appreciated."

"Many thanks for your kind and so valuable assistance which has helped to avoid bad weather and made last passage almost pleasant."

"As for present passage though it's too early to say because it's not yet completed (I am superstitious, as most of the seamen), I have to admit that it's not so bad and your good team should be credited for giving so valuable recommendations."

"Thanks to you and your crew for a great ride. We made up all of our lost time and will arrive...on time."
