Note the small ships are small boats/barges called Chatas. These were built to only carry a 68pdr or 80pdr gun. The Chatas had no propulsion, so had to be towed.
I chose to not do full ship lines or ratlines. I figure at this scale just a representation is sufficient. The areas on the ships where there are ship boats on the sides, I did not want to struggle fitting in the ratlines. Who knows, maybe later I will.
