Nick,
You said "leave the plugs open". Will water not enter into those holes from rain or snow and settle in the hull? If it did I know it would eventually evaporate or freeze. My hulls are solid and have no leaks or water in them and I know that they breath through the tubes in the pylons. I see the point of leaving the plugs out (for more air circulation), but still feel like I'd be better off with them in. Is this a valid argument? I definitely don't won't a delam problem in the future.
