Octuple scull

An octuple scull (abbreviated 8X) is a racing shell or a rowing boat used in the sport of competitive rowing. The octuple is directed by a coxswain and propelled by eight rowers who move the boat by sculling with two oars, one in each hand. Like a coxed eight, an octuple is typically 65.2 feet (19.9 meters) long and weighs 211.2 pounds (95.8 kilograms).[1]

Racing boats (often called "shells") are long, narrow, and broadly semi-circular in cross-section in order to reduce drag to a minimum. They usually have a fin towards the rear, to help prevent roll and yaw. Originally made from wood, shells are now almost always made from a composite material (usually carbon-fibre reinforced plastic) for strength and weight advantages. The riggers in sculling apply the forces symmetrically to each side of the boat.

When there are eight rowers in a boat, each with only one sweep oar and rowing on opposite sides, the combination is referred to as a "coxed eight." In sweep oared racing the rigging means the forces are staggered alternately along the boat.

gollark: CraftTweaker actually can dump all recipes as ZenScript or something, and I wrote a parser, but I got rid of it because squid had an alternative of some sort.
gollark: It's kind of annoying that basically all autocrafters require you to manually program in all the patterns.
gollark: Isn't there some Opus thing to mount files from HTTP (if you don't need to edit them)?
gollark: I'll probably run gzip over it in my thing anyway.
gollark: My code captured every font character as an `ImageBitmap`, but apparently only Chrome implements the bit of the standard which would allow me to scale those correctly.
