    Posted: 21 January 2023 at 19:17
Hello, I want to remove the bobstay chain plate on the bow (don't know what it is called). I want to have a large strong pad eye welded to it as a snubber hard-point. Has anyone removed this part before?

Looking at the inside of the chain locker I see bolts and I also see the attachment point for the forestay. Is the forestay attachment the same chain plate, or is it a two-piece thing?


If anyone has ever removed this part, I would love to hear more about it.

Thanks,
John

John,

On our 575 we removed one of the bow plate bolts and replaced it with a 12mm stainless steel bolt with an eye and attached the bob stay to that.

Hey John

Have you consider a bridle snubber hooked to both forward cleats?

We have made a bridle snubber "Y" type with 4m "arms" and 10 m of 16 mm Nylon with an HDG eye in the end where I attach a 14mm Dynema soft shackle and 1.5 m long 12mm dynema strop (double eye) covered with anti chafe. The strop is used to do a "bag Tag" around the chain so it does not damage the galv.

Cheers,
GG

Hi GG

We also have a Y type snubber, but your set up sounds great.

Do you have a few pictures showing your set up?



Merci

Hello Marc

I wont be in the boat for another month so I can get any pics, but in the mean time basically this is a Y snubber 12 m long 16 mm / 8 strand - Nylon - BL5900kg - Certified - Japan origin  with 290 mm spliced eye loop on each branch for each cleat. These and the branches all the way to the "trunk" splice are covered with chafe-Pro Sleeve so there is no risk of chaffing against the bow when the boat is "sailing" at anchor. The trunk is 9000 mm long with an internal thimble on a splice. 14 mm chafe-pro (USA) sleeve covered Dyneema 78 soft shackle and a 12 mm chafe- pro sleeve covered Dyneema 78. See hand sketch attached.

1200 mm fully chafe-pro sleeve covered strop used to do a "bag tag" loop around the chain. Under the tension of the snubber the strop will not slip and will not damage the chain galv.

I live in New Zealand so our South Pacific weather is well known. This set up has not failed once in 50+ knots and provided us with a safe way take the load from an already Hanse's under-sized windlass. 
Pulling loads are shared by each fore cleat rated to SWL 4000 kg (according to Hanse though).uploads/5828/H_505_Snubber.pdf

Cheers.

Hello
Am I missing something in this topic?
A BOB STAY is proposed to counteract the upwards forces on the bowsprit of the gib-gennakker forestay.
A SNUBBER is proposed to take of the loads on the anchor windlass and bring those to the SB and BB cleats and prevent the boat from to heavy swinging while on anchor.
Am I Confused wrong or is my English to bad?

Wild,

Your understanding is 100% correct. The thread went astray.

Wayne 

The original post was started by John requesting help to remove the bobstay to install a pad eye on it for a SNUBBER anchoring point.

Then an alternative for a snubber was proposed INSTEAD of removing the bobstay chain plate which is a significant job as it requires to deal with the forestay anchoring as well.

hope this helps.

Cheers
