Model speedboat enthusiasts try out their craft on a park lake.
Titles read: "MODEL SPEED-BOATING" (Dublin issue).
Various shots of model speedboat enthusiasts preparing their craft then putting them through their paces on a park lake. A large crowd watches.
Note: this looks very familiar! It's probably from an earlier newsreel issue or cinemagazine - could be MODEL BOAT REGATTA in 38/54?
