Large torpedo boat? No.

Here is something different; at first-glance this looked like a huge David but it was a unique log-raft:

They were known as Benson log rafts. They were towed in the open sea along the Pacific Coast, dramatically lowering shipping costs from railroad or traditional ocean barge transportation. Held together by large logging chains, they were the first ever seagoing ocean-worthy logging rafts to transport intact millions of board feet over a long distance. The first was launched in July 1906[10] and last of 120 in 1941. About half were "deck loaded", with processed lumber such as shingles, fence posts, and poles atop the logs, maximizing savings. Four of the 120 were lost due to fire or storms.

Today using a modern Ferry like the CAT Ferry the journey from Nova Scotia to New York is about five and a half hours, how long would it have taken with the Benson Raft? There must have been some weight to that thing considering it was 700ft long.
