You could try these two links:
http://pcf45.com/boat_tour/boattour.html
http://www.swiftboats.net/
In the second site, click on the "Background" tab and click down near the bottom of the page.
I built the Swift a while ago and played with the idea of detailing the interior. I decided that 1) my scratchbuilding skills were not up to it and 2) you can't see a whole lot anyway.
God luck and post some pics if you do it.
