After being a disciple of the Bruce (genuine only please) for many years, the Mantus is now my primary anchor. I've been enjoying it's very VERY quick setting ability and take comfort (though rarely actually use) it's short scope holding ability.
Last weekend we had some more (unintentional this time) fun.
On Memorial day, in my neck of the woods, there was about 13ft of tidal movement and I was riding that sleigh-ride of an ebb back to my slip. Only problem is that (as you can see from the tide bottoming off the chart) there wouldn't be enough water behind my slip for me to get in. So I had to pick somewhere nearby and anchor for a few hours.
I chose a little bay that I'd passed a million time but never anchored in. It is only about 4KM from my slip, so I'd never had the need to anchor there. Actually that was plan "b" but plan "A" (grabbing a state park buoy in another nearby cove" was thwarted when I saw the buoy about 4 feet from shore.
I pulled into said bay, and with the wife at the helm we began regular anchoring procedures. We agreed on the spot, she stopped forward motion, and began reversing in idle, and I let out the anchor.
Only problem is, there was about a 2.5kt+ current swirling in the bay and it took us backwards at at least that speed. So I'm paying out the anchor and I don't realise how fast we're going in reverse, because I'm only looking at the wake on the chain, not our motion relative to the landscape. I think we're doing about 0.5kt in reverse, but we're actually doing 3kts or more in reverse.
I try and slow the chain freewheeling out and the chain stops paying out as the clutch catches (normal for my windlass) and suddenly I see the anchor chain going out at a very, VERY flat angle in front of the boat.
I've let out about 65ft of chain in 40ft of depth and she's caught and we're puling harder on it (in an instant) than I've ever seen us do, and we typically back down at 2/3 throttle in reverse. Suddenly the bowsprit dips down TWO FEET
and we come to a sudden stop.
I'd say she's set.
Actually, I'm a bit stressed that we've snagged a cable or something. Turns out this bay is all rocks. Probably has too much tidal flow and current to accumulate sand. Who knows, but it's low tide and all I see are rocks in every direction. Likely snagged a rock or cable....
I let out a bunch more chain to make 4:1. Then the current picks up and we're surrounded by standing waves. It's like we're anchored in a class-something rapid. I let out more chain. Being anchored in a rushing river is making me nervous, but then again, I snagged a cable, or sunken submarine right? I might never get my anchor back, but at least we're hooked up well....
Come time to bring her up and the chain was really, REALLY stuck twice. Both times brute force with windlass and engine freed it from a rock. Then, the anchor itself. I could tell when we got to her, and I expected an epic struggle. Nope, she came free with just about as much effort as she does from sand.
It seems to me that the anchor set really well, and REALLY FAST in rocks on a ridiculously short scope and yet was able to be retrieved with ease. Good anchor design or dumb luck on my part? Who knows? Was it the anchor that even did the set or the chain that found a rock? Again, who know, though I'd bet it's the anchor....
A nice reminder that you never have it all figured out when it comes to anchoring in the Salish Sea....
