lass. I moved the thread to its own thread.
Delta is Lewmar's model name of a plow-style anchor.
you'd be looking for between a 22lb or 35lb anchor. I had a 22lb Rocna and then later a 25lb manson supreme on my 2800 SCR. I would look at the new-generation anchors like Rocna, Manson Supreme, Spade. I am not a fan of old anchor designs like Bruce, Danforth, Plow. New generation anchors overall, perform much better.
Use the sizing chart from each manufacturer.
Windlass style (e.g. Horizontal or Verticle) are determined by the space available in the anchor locker. the size of teh windlass is determined by the size of the anchor and chain.
You would typically be using 1/4" chain and 1/2" line.
