Thats good to know.... I wouldnt at all mind the sound of just the water being expelled, was more concerned with the actual motor noise!
Now see I have another issue. I bought a 8a cat. on my cruise and for that price can go all the way up to 8e if i choose.... i have friends on deck 8 (verandah) in the rear of the boat... but i can take the balcony room up deck 10 (panarama) on the side of the boat.... does the deck or position even matter? or am i overanalyzing this?
