Set screw....

[Cztomo]

Couple weeks ago, while sailing I hear loud thump. Can find what was it, till my friend show me a large set screw he found on the front deck by the hatch.
Can anybody tell me where this came from??? Thanks.
Boat is 1997 Hunter 336.

Some forestay furlers have set screws to hold the aluminum extrusions together.

I forgotten to mention the size of the set screw, its a M10 x 20mm long.

M16x20

Upper swivel furler set screw?
Have you used binoculars to check your rigging?

Some Harken jib sheet cars use a set screw like that to hold the pin in the car.

While prepping the boat for winter dry storage, I found the place where the set screw came from. Please bear in mind I just purchased the boat on the summer..

Wow, from mast to foredeck - must have had some force on that batten when it gave way.

Glad to hear you found out where it came from.

So...it occurred to me that tossing a set screw like that onto the deck of a neighbor's boat in the marina would be a horrible prank. You know, the guy who's a loud drunk, has slapping halyards, and lets his dog run loose in the marina.

And you really think the guy would notice the set screw on his deck?

True.... it's the fastidious boat owner who would go nuts looking for the source.

Actually did that to such a fellow years ago.. trouble was he knew his boat so well that he knew that particular part couldn't have come from his boat....

Many years ago, One of the more nasty tricks that some guys did during competitive racing was to fire a bolt or nut into the top section of another boat’s main sail using a small slingshot. I’m not saying I condone this, but it has some humour to it.

Consider yourself lucky....Murphy's first rule states, " Objects dropped or falling on a sailboat will issue a sound report to get your attention. You will hear 2 bounces followed by a loud PLOP.".....
