Tonnant

 Back in 2005 Bursledon Regatta suggested as part of the event a reenactment of the battle of Trafalgar, using dinghies which were made into "fighting ships" with the addition of wrap around hardboard or plywood panels. Actually one of the entries went a little further, it was pretty much a scale model with full rigging based on a mirror dinghy hull.

 My effort was somewhat more modest with masts from PVC pipes and fully armed with plastic buckets and water pistols for full broadside. 

My plywood panels are long gone, can't even remember what I used them for, but along the river is a nice reminder of that battle 20 years ago.

Great set of pics here  in fact pictures of all the recent Burelsdon themed regattas.
