Long boat is the eighth most common still life on Adam P. Goucher's Catagolue, being less common than pond but more common than ship-tie. Among all still lifes with 7 cells, it is the second most common, being less common than loaf but more common than eater 1.It is also the tenth most common object overall on Catagolue.
The long boat has two six-cell predecessors. The second can be turned into a glider by placing a tub with centre four cells below the "bend" in the pattern.

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 synchronized 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.
A long boat can be used as a 90° or 180° one-time turner.
