timber & glass anchor sprit

Might be interesting to introduce some exposed carbon fiber to the "look" of the boat?

Awesome build!!

Maybe you can hide a chrome within a nice piece of hard wood similar to above logic but more aesthetically pleasing to Skinnydips's lines?

It is much easier to incorporate on a longer sailboat pulpit but on a 21' boat trying to keep it proportional is the main challenge.

I would try to use an already tested and hide that to the lines with wood..

Thanks for your responses cape man, Jaysen, tcason and Ilker. :D

They are helping me clarify which way I want to go. I want to keep it functional and simple, as cape man stated in an earlier post. I'm attracted to something like the pic below.

No boat building today due to oyster reef restoration stuff.

Will post sprit decisions tomorrow after I've slept on options..

Sticking with simple and functional.

The anchor shank will pivot over a 2" wide roller set in the split of the sprit. This will be wide enough to allow shackles connecting anchor, chain and rode. In the pic below, the 2" wide opening will be a little forward of the capital S on the word 'Supreme' on the anchor.

The forward most three of inches of the slit will be only a little wider than the anchor shank. This will prevent the anhor rattling around when it is stowed.

I think this should work.

As discussed earlier, following Jaysen's suggestion, the bulk of the sprit will be countersunk below the deck line. The top +/- 1/2" may end up sitting proud of the deck line for aesthetic reasons. Will make that judgement at the time.

For the slow guy...

You’ll have a 2” roller about 6” back, a cut out about 1.5” in diameter to allow chain to go over roller then just the 1/2” slit forwar of the cut it to the end of the sprit. Yes?

Any plans to line the wood edges that are likely to take load/chaffing when the anchor is deployed?

I think the problem with the standard here is that it allows the anchor lateral movement which creates banging.

I think.

On my CS winch pulled it snug into the rollers no banging whatsoever, not sure GB is gonna use a winch though

As I said, “I think”. I also “think” the anchor will only be pinned for securing it.

There’s a burning smell right now. Thinking is bad for me.

Yes, and internal edges will need to be lined with ss plate.
