I found a lot of really good information on the web.

anatomy of quality seacocks.

The pictured sea cocks are Groco sea cocks which are considered top end and very pricey, as always you get what you pay for.

I have a created a static page under the info index with the above information on it. If anyone knows what kind of sea cocks and what size were standard from the factory it would be interesting to put up here. So any thing anyone has to contribute about their experiences with their boats and what kind of sea cocks they have and the locations of them would be valuable. Once we get some data here on the forum from people I will consoidate it on the Sea Cocks page.
