I noticed the same thing but got used to it after a trip or 2. I will tell you that if you hit something like a piece of floating firewood you expect to see water gushing in but when you look all is dry. WHen you pull it out of the water on the trailer you crawl under to see how big the gash is and how hard it will be to fix and you can't find a spot the inspect.How did the test run go?
I was surprised by the noise. The sealed airspace between the bottom and the deck is like a cello. I told my wife, "It sounds like a cello with outboards." Although I was neutral on the foam vs. air argument, the noise has pushed me to the foam side of the argument.
I had wondered about foam making a difference in the sound of water slap. I am not a big proponent of foam as I have seen to many examples of waterlogged foam but I would entertain the thought of having it in the cuddy and the main cabin and not under the fish deck. Just my thought but it is not a big enough deal for me to tear out to replace. The air works fine. I would be interested in knowing if those who used pool noodles have the same echo chamber effect?
Sounds like a success. Where did you trailer to and launch from? Ken
