Could you post a pic of the setup or give a fuller description? I am having trouble visualizing where you attach the snatch block

Another Snubbing Option -- Lawrence Killingsworth M40 Ta Ata Ori, - Wednesday - 08/30/06 - 1:46pm
Another option, Steve, as shown somewhat in the photos of Ta' Ata Ori on this web site, is to have a dedicated snubber line attached to the point where the bobstay attaches to the hull. On the anchor end, the snubber line (5/8" or maybe 3/4" nylon line) has a hook that attaches to the chain. No knots to tie. This arrangement keeps the anchor attachment low, so less pitching. Also, completely out of the way of the bobstay, dolphin striker, etc. There is some controversy associated with the having anchor stress at a point near the waterline, but the bobstay attachment area on the hull is highly reinforced and the snubber has worked fine on Ta' Ata Ori for many years.

can do... -- Randall, - Wednesday - 08/30/06 - 2:00pm
...a pic, but i won't be on the boat this weekend, so it will be a while.
a better description is difficult, but let's try this: for the bridle, find a random piece of (1/2 inch?) used line in the locker 6 to 10 feet long (?); tie the bitter ends together to form a loop; fold this loop in half, twice; lay this folded loop over the bowsprit (in that space just in back of the cranse iron and just in front of the pulpit); now on each side of the bowsprit should be two loop ends that hang just below the bob stay when taut; clip the snatch block to these loop ends.
the bridle will rest on the sprit and lay over the whisker stay turnbuckles; thus the double loop, which helps distribute the load and the chafe. Extra chafing gear would be in order, but I've noticed very little line wear to date.
i haven't experimented w/this much. the first thing I tried (above) worked so well, I've not made any modifications. if the boat is sailing on anchor much, you will hear, from the vberth, the bridle shift position back and forth, but the noise is nothing like the wake-the-dead thunking and thundering of chain or snubber full across the bob stay.
ya, so a picture will be worth a thousand words... :)

Step one: the loop -- Randall, Murre, M31, - Sunday - 09/10/06 - 11:37pm
Select a 10 foot +/- length of rope; tie off w/a square knot and whip the ends (so things look neat and nautical for your mariner brothers).

Step two: lay over sprit -- Randall, Murre, M31, - Sunday - 09/10/06 - 11:42pm
Double the loop over twice and lay it over the sprit and over the outside of the whisker stay turnbuckles.

Step three: attach the block -- Randall, Murre, M31, - Sunday - 09/10/06 - 11:45pm
Attach your block ... without falling overboard.

step four: run the snubber -- Randall, Murre, M31, - Sunday - 09/10/06 - 11:52pm
Run the bitter end of the snubber through the block and BACK ON DECK. Attach to chain w/a rolling hitch. Run both snubber and chain through chain roller. Feed out as desired...

Step five: relax -- Randall, Murre, M31, - Monday - 09/11/06 - 12:26am
You're anchored.
Advantages:
-no extra stuff to purchase
-no holes in your bowsprit
-easy to deploy
Disadvantages:
-chafe on the sprit and whisker stay turnbuckles (but this isn't much in moderate conditions when used for weekend anchoring. Besides, it's a junk piece of line you're using: if it chafes through, use another. That, or install extra chafing gear.)
-doesn't entirely eliminate snubber rub on bob stay, but rub is only audible when boat is sailing around on anchor (i.e. is a vast, vast improvement over nothing at all.)
