This brings me to a big question about the hammock rails themselves. Marquardt shows them boarded over, in effect raising the height of the bulwark. Unfortunately, there doesn't seem to be any good contemporary evidence on whether Cherokee/Cadmus class brigs had hammock rails that were boarded, or left with simple netting. John Chancellor, the maritime artist and historian, contrary to Marqurdt, is convinced they were not boarded over. He says the hammock nets were often covered with tarred or black painted canvas which would look like solid boards from a distance. I'm tempted to go with Chancellors view.
Then we come to the diamond-shaped decorations. They puzzle me a lot. All the accounts say that these brigs were fairly plain ships, with few frills. Minimal stern decoration, and some even doubt the presence of a carved beagle on the prow! Why then would they take the trouble to add all those carved diamond decorations? Were diamond decorations used on any other Royal Navy ships? I haven't found a single example yet (but stand to be corrected). The only example I have come across is a contemporary model of the Belle Poule (which returned the body of Napoleon) in the wonderful Paris Maritime Museum. Admittedly, PG King's rough sketch of the Beagle's deck does show faint diamonds below the hammocks, but drawing was from memory in 1897, 62 years after he served as a midshipman on the Beagle. I cant believe that HMS Beagle alone in the Royal Navy had diamonds on the hammock rails. I'm drifting towards adding soft netting (probably black painted fabric), rather than boarding, and omitting the diamond decorations. Feedback/opinions welcome.
