I can't really think of a reason why the piston returns to the original position!! any ideas?? I made a transparent QEV coaxial cannon out of the preform of a bottle. This was inspired by a Nighthawkinlight's project, although I added a transparent barrel and had to make everything work with a wooden piston and o-ring seal. The breech seal is just a piece of rubber from the inner tube of a bike tire. Thanks for watching!

The longest of three 100+ metre yachts built simultaneously by Benetti at its Italian facilities, the 108-metre flagship FB275 departed Benetti’s yard in Livorno on July 26, 2019. Featuring exterior design and décor from the British RWD studio, her interior design is from the drawing boards of Benetti’s in-house design team. With a steel hull, aluminium superstructure and a naval architecture by Pierluigi Ausonio, the 108-metre FB275 is the longest Giga yacht ever to be delivered by Benetti.

J109 "Going to Red" beating to windward had a fine line to thread the gap between Cape 31 Shootgun and the Corbt 37 Impetuous on day two of racing of Cork Week 2024. Race 6 ended up being the trickiest race of the day with the wind getting light and variable towards the top mark before a 30 degree shift on the last beat turned the race on it head. The race committee did a good job to finish the IRC 1 boats at the top mark to limit the damage from the variable winds. The team at Bottom Up Boats hope you like this short clip from our week of racing at Volvo Cork Week 2024
