I have no idea what a spar is when used as a noun and "a running bowsprit in its extended position" is incomprehensible...
However, the other day, I found myself on a sea vessel (yes, I did) and I was walking around on the poop deck (whatever that is). I stumbled (it was already shaky footing, the waters were choppy) and looked around to see what I tripped on. It was an eel and it was alive! I don't know how it got there but I needed to kill it immediately. I grabbed the nearest object (a fid) and smashed it to death.
