I design my ships after historical precedents, whether Age of Sail Sixth Rates, Ships-of-the-line, Sloops-of-War, & Seventy-Fours (by number & size of guns); Ironclad era Frigates, Battleships, & Cruising Battleships (by role); or WWI Corvettes, Dreadnoughts, Torpedo Boats & Battlecruisers (by tonnage & speed).
