There are many of them around, it has a twin-boom nose section:
Well, -I've seen those flapping around underneath my boat at times.
-First time was kind of scary though, we were anchored at a coral-head with sandy bottom underneath us. Suddenly the bottom turned black -the "span" of that thing must have been 6 to 8 feet......
Luckily they are gentle, harmless creatures.
Now, back to the twin-boom tail!
