I love the brass portholes on the tugs and wonder if they could be installed on the curved surface of a 22. C-batical has some nice aluminum ones and I think Red-Fox had a pair. Any ideas ?
Check out the Vetus website: http://www.vetus.nl/en/index.php.
Vetus seems to be the only company making smaller portlights/holes. I chose the smallest oval porthole and the curvature of the cuddy wall did not pose a problem. Vetus is a Dutch company. They make a very nice product but getting their products in the US was difficult for me. I ordered my windows from Marine Parts Source: http://marinepartssource.com/index.asp. It took several weeks, however, for me to get my windows.
