I just received my September/October issue of 'Good Old Boat' magizine, and if you don't subscribe I highly recomend it. 

There is a piece on enlarged scuppers and cockpit drains with  check valves, that is worth considering!

There is also an article on a 15 gallon ridgid  8 inch PVC pipe holding tank that looks very interesting.

But I must say, that the article that is using twine to terminate the lifelines is very lame and down right dangorous, what was   Karen, the editor, thinking about!

And just as an aside, off shore racing rules do not permit vinyl covered lifeline wire because the wire condition can not be checked or verified.
So when your going over the side and you grab the wire, just hope it isn.t ruster away.

 So... when replacing your lifelines , go with plain wire, not as pretty, but A lot less $$$$
