Found this and "Catastrophe at Spithead" on Kindle for 99cts apiece. I believe in this book Marsden makes the case for a high-castled, top-heavy ship. Normally, I'd check them out from the library, but this seemed well worth the expenditure.
I'm a big fan of the Internet Archive, which has a very large selection of hard-to-find books. At first I was concerned that the books were pirated, sort of like a literary napster. But once I researched it I found that several libraries are involved. It looks like they scan books they no longer have the room to display for borrowing. Most of the scan jobs are good, though I've occasionally run across missing pages.
Also a good source for information.
