Hello again, gentlemen!

Thank you very much for your responses.

Schnipster, I have not tried a Pro Boat silence yet. I am just gathering information. I will try to have a quietest one.

Ron, I have already added some foams in the hull, but still it did't help much to reduce the noise. Maybe I need a better way to do it again. Could you give me more deatail of adding foam in the hull, please?

Thank you very much for your attention. Have a good day and enjoy boating!
