@MrMoose great minds think a like, I purchased a factory Yamaha bow cover for my boat and it just arrived yesterday. Last year I drove one of
@robert843 skis over and my buddy drove my boat over and from what my buddy and my wife said is that they didn't take any water over the bow. With 4 trips to Bimini and back we have never taken water over the bow, however I thought this was a cheap insurance to help cheap things dry inside the boat in case we ever do take water over the bow or if it starts to rain.
I plan on putting the life vests on top of the bow cushions under the bow cover. This way are out of the way in the passenger area but if needed they are easily accessible by opening the bow pass through door and reach in to get them.
Also, I plan on putting some blow up tubes, the type pulled behind the boat, on top of the bow cushions to support the bow cover. I don't like only having the center pole of the bow cover is sufficient enough to support the cover in handling the wind load or water load if we take a wave over the bow, I won't be using the pole while the boat is underway. I'm using blow up tubes so that when they are not needed I can deflate them for easy out of the way storage.
The bow cover I got for my boat (boat model year 2007-2009) is Yamaha part number MAR-230BC-VR-CH (charcoal color) with the best price I found being on eBay at $148 delivered. I won't be installing mine for a couple of weeks, too many other projects to finish, but when I do I will post my process.
