I need to replace my.... thing?

i have a stern pulpet, or some such thing.
the wood is rotting.
bolts on with two bolts. but what about the rigging?
can i just unhook it for a week at dock?
or do i need to run the hallyard down and hold it in place that way?
does it need to be wood? or can i have the welder fab it up in aluminum?

and what is it called?
sorry, its kinda new to me

Not that I would really know, but could you post a pic of what you are referring to. I would be interested in seeing. Thanks!

Re: i need to replace my.... thing?

looks like a load bearing spreader bar for your mizzen backstays,so any replacement needs to be structrally sound enough to take the loads imposed on it by the mizzen,all the other attachments are purely surplus to its pupose

Re: i need to replace my.... thing?

I read somewhere that Red Oak is bad. I also recall White Oak was "OK" if properly treated. Gougeon Bros. Book might shed some light on your project. It is on their website for free download:

WEST SYSTEM | Use Guides

Hope that helps.

Re: i need to replace my.... thing?

Great title! I understand why there is confusion because if you were to post a picture of your "thing" you would get into trouble

Never replaced mine so I can not help you, are you sure a pill wouldn't fix it? I whole hearty wish you good luck.

I guess I should have been more careful asking someone to post a picture of their.....thing.


Thread drift.....

Re: i need to replace my.... thing?

Me would rig a halyard just in case - especially if the Mizzen used as a "perch" for a radar or windvane.

For replacement my natural inclination would be for s/s ($$$), but failing that I think aluminium would be ok (a decent thickness and some form of box or even a girder?! shape) - my thinking is that the strength in the current arrangement comes from the pull from below and not from either the material itself (apart from for the fixings) nor from the hull fixing (primarily in compression?).

Of course I am no rigger nor structural engineer - hence my comment that me would favour s/s!

BTW, in the second pic I am curious as to why a hatch appears to be there? Does it lead to the head?!

Re: i need to replace my.... thing?

In those 2 new pics the "hatch" is not there - but nor is the bar it sits on!, at least it does in the second pic in your original post (at the top - it's wood and has slats).

Seeing those pics a thought has occurred to me, that mizzen is a decent way forward (she is not a Yawl!) is the bar really needed? (obviously depends on Mizzen Height, at 53' of boat likely it goes up a bit! - and probably other stuff to think about!) - but if a retro fit by a PO perhaps he simply got enthusiastic? Just a thought.

Re: i need to replace my.... thing?

i had wondered that myself.
i cant for the life of me figure out what the two solid loops are on the stern by the steps are. perhaps where is was originally rigged?
of course, there are many mystery's i find every day on this yacht.

and i think my height above the water is 55'. both mast are the same height.

McMaster-Carr carries structural fiberglass shapes that you could use to fabricate a new thing.
Thanks
