Now here's a hobby I didn't know existed: members of the North Texas Battle Group build elaborate radio-controlled balsa warships armed to the teeth with CO2-powered BB guns, then launch them in a nearby lake and battle it out. Also on board are pumps to evacuate water taken on after direct hits, independent rudder and propeller assemblies, and an auto-deployed float to help salvage the not-so-fortunate sunken wrecks. And it's not just in Texas—similar clubs are staging regular mini-naval battles around the world. —John Mahoney

The heavy artillery operates like paintball guns
clubs generally have rules for what the ships can be made of. thin Balsa is used because it is cheap and actually allows the ships to be sunk ensururing a fair and fun battle.often hte huylls are made of a number of pannels allowing the replacement of dammaged pannels easily.
This is a fun port with players often starting with a small cargo vessel anor trawler and working hteir way up to battleships as they gain experience.
Many scenarios are played, with favourites often being convoy escorts as this allows both junior and experienced players to participate and has a real life flavour.
