Long boat is a longer version of a boat that was discovered by the JHC group in 1970.
It can be trivially extended to form longer versions of the boat.
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.. 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.
Long boat can be constructed using only 3 gliders; its first glider synthesis was found by John Abbott. There are multiple ways to synthesize a long boat using three gliders, two of which involve a glider hitting a beehive or loaf in a way only possible if the beehive or loaf had just formed. This can be useful in soup-based glider syntheses, as the beehive/loaf (predecessor) can sometimes be synthesized together with another object more cheaply than synthesizing the two separately.
