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