A thought about the wooden plugs sold for leaks
I've had over a few years 2 through hulls that broke, one was due to my negligence
Both times I've used wooden plugs top stop the inflow of water, the plugs were made of a soft absorbent wood I thinks it's named Tupelo wood.
When I put them in I tapped them about 5 or 6 times with a small hammer then in about a half hour I tapped it again to make sure they were secure
The first time I was up all night checking them every 1/2 hour or so.
Anyway they worked flawlessly and when I had to pull the plug out I had to use a 15" Channel lock pliers for about 3or 4 minutes to get it out.
Now the reason I'm saying this is because some marine retailers are offering high end (Price Wise) Teak plugs that don't swell and will pop out.
So beware when purchasing plugs. <img src="http://www.traveltalkonline.com/forums/images/graemlins/toast.gif" alt="" />
