Hi guys, not wising to beat this issue to death, but I was down checking the boat today, and mindful of the interest others have expressed re this rather novel and new anchor concept, (especially as it is apparently about to become available in the North America), but tempered perhaps by the possibility of an anchor with slotted shank being at risk of self-tripping at a bad moment, I clipped my anchor to the samson post and had a liitle play with it.*
What I found was what I sort of expected to find by experience of using it for now about 8 yrs.*
Back to the the slot...the 1st pic is looking at it from behind, showing how the longer than usual U-shackle sits in the slot with the shackle bolt through the slot - NOT the U-shaped end - in that configuation it would slide too easily.* The way it is here, any off-line tension tends to lock the shackle in place because the slot is square-edged, and slightly rough.* The shackle only must be stainless.
This is why the pull has to be from above and in line with the slot for it to slide forward to the fluke end to enable the trip when fouled.* This is demonstrated in the 2nd pic where I slid it down the slot about 1/3rd way and then exerted enough pull on the chain & shackle at a forward (~ 50 degree angle) away from the bow, it was pulling the whole boat towards me against the breeze, yet the shackle did not slide down the slot to the fluke end, but locked where it is.* This held good for all angles except directly in line with the shank.* In a real life situation, that means the whole anchor would have been rotated and reset itself as wind or tide effect clocked round, well before any self-trip effect could occur.* Thought you might find these interesting.
