Long boat is a longer version of a boat that was discovered by the JHC group in 1970.[1]

Commonness

The long boat is the eighth most common still life in Achim Flammenkamp's census, being less common than ship but more common than ship-tie.[2]. It is also the tenth most common object on Adam P. Goucher's Catagolue. It is the second most common 7-bit still life, being less common than the loaf but more common than eater 1.[3]

Synthesis

Long boat can be constructed using only 3 gliders; its first glider synthesis was found by John Abbott.[4]
