I moor my WB 250 in an area of the Connecticut river that is relatively unprotected. I have to worry about storms and boat traffic wake. There is a cove that I can moor the boat in that is well protected and has many other advantages. The problem is that the cove is very shallow at low tide. The harbormaster says there is about a foot of water at low tide. I think there is more water than he says, but for the purpose of discussion, lets assume he is right.
I do not know if I will damage the centerboard if the boat is moored in a foot of water and it drafts 1' 8". It will clearly be on the bottom. It is a soft muddy bottom and there is nothing hard to hit. There are a number of similar draft sailboats in the area who are taking this risk.
I guess I don't understand moving a boat that is on a deep water mooring, if it is an actual mooring. I can think of nothing good coming out of that particular shallow water mooring. The centerboard is already the weak point of the C250 WB series. You indicated you had a trailer in the previous post. Can't you retrieve the boat if the weather turns sour while on a deep water mooring? IMHO I wouldn't think twice about moving it.
Check your draft. There was a discussion a while back about rudders and how the third generation rudder was held to the depth of the draft. At any rate I checked the draft on our boat and it is 29" which is deeper than Catalina's literature states. You run the risk of severing the centerboard cable in a hard grounding. I agree with bear stay on the mooring if it is in good shape and sized right. When I was on a mooring I used a bridle system which meant that two lines would have to fail. Since I was still nervous even with two 3/4" nylon lines, I attached a third to the bow loop.
