Jason it depends on what type of weather you expect the system to be able to handle; a
CQR is hardly the best type, but it will probably not give you much in the way of setting problems around the area. However, it is a touch small for your boat in terms of holding power, particularly in softer stuff.
I must also pick up on your mention of the sentinel; do not be under the illusion that this in any way will help your
anchor. Kellets do not increase the ultimate holding power of any
anchor; they are not something to be used in the context of performance, particularly a weight of only up to 30lb.
We have cruised through the area, and frankly I would not be happy with that set-up overnight, let alone leaving the boat. I would upgrade the
anchor to a new generation design of similar size, up the chain to at least 50', and put the sentinel somewhere out of the way for the rare occasion I might want it. The existing tackle would make an acceptable 2nd
anchor system.
I would keep the
Fortress as a kedge or stern
anchor, but not the 35
CQR.
Probably not what you wanted to hear but there you have it.
