Where it comes from? Water in hatches.

[Kaito Matsumura]

Cause I'm Japanese,I can't speak English completely,sorry.

I enjoy the sailing life in 420.
But unfortunately, there is water in the hatch of my 420 after sailing practices.
Where it comes?
I want your opinion.

Greetings Kaito!

A picture is a great start to understand the problem...all I can suggest for now is...can the hatch be adjusted or is there a gasket that needs replacing?

I found this one on the web...where is the hatch in question?

Thanks for repling.
"Hatch" means rooms not to sink.
(Actually,I knew that hatch means a door of airplane just now.)

If your 420 is like the ones I sailed in college, the most common place for the buoyancy tanks to take on water is the hull to deck joint. The second most common place was the hardware attached to the tanks, like the jib blocks and can cleats.

One easy way to find the point of water ingress is to pressurize (very slightly like 1/2 psi or 3 kpa) the tank while washing the boat with soapy water. The bubbles will show you the leaks.

To me "hatch" evokes a vision of this...wish I knew how to help!

I had a similar problem on a Wayfarer World.
You need to pressurise your bouyancy tanks.
This is how I did it.
You need a standard dinghy drain fitting and plug, a domestic vacuum with an outlet nozzle, a length of plastic pipe that is a push fit into the drain fitting and some duct tape or similar.
Fit the drain fitting into the tank that leaks somewhere that it won't get in the way.
Push the plastic pipe into the fitting, connect the other end of the pipe to the exhaust of the vacuum. On my vacuum the hose connected to the exhaust so I just pushed the plastic pipe up into the vacuum hose.
You don't need much pressure.
Start the vacuum, I found all my leak points just by listening to the escaping air, but soapy water would make sure.
Then all you have to do is fix the leaks ;-)

I pic might be helpful. Don't worry about the English, it is better than most of our Japanese.

I am guessing that "hatches" refers to the buoyancy tanks (or compartments intended to be watertight) that run along both the starboard and port sides (maybe in the bow as well). Sailmonkey and Bluebeard seem to have correct identification and possible methodology for a determination and resolution.

Unfortunately, I was unable to get photos found on Google to copy to this reply, but the search term used was "Nautivila 420."
