Keith,
I only had time to read a portion but appreciated the coverage. As usual for woodenboat, the pictures were unique - I haven't seen them published anywhere else.
I have an out of print history called "Racing and Cruising Trimarans" by Robert Harris. This covers early development by Piver, Crowther, Kelsall, and Newick. As a bonus it has a series of photos of early beach trimarans that use to sail against "C" class catamarans. There are pictures of Crowther's "Jaberwoky" and Meade Gouegon's "Victor T".
