A port size of 4" to 5" in front of the pylon is the correct size. If you consider behind the front pylon the the correct size is 5". Anything larger than what I have recommended will weaken the structure.

Bob,
Thanks for your words of wisdom, duly noted. As Patrick (yoh) has stated earlier, I have never concidered ports a requirement to keep the hulls dry. I don't understand the obsession with ports. I bought a 1980 that sat for 5 years, yes it had condensation water in both hulls (quart or so) and the plugs were closed. It eventually stopped dripping and it doesn't weigh that much over minimum (not enough for a sailor like me to make a difference). If you can, keep your boat stored with the bows up or lift to drain as often as possible. Leave the ports for structural repair jobs.
