I recently bought a Daysailer II with a tabernacle. I assumed the tabernacle was fixed to the foredeck, and when I first looked at the boat, I didn't even bother to check whether this was the case. Unfortunately, the first time I rigged the boat, I discovered that the tabernacle is attached to a tube that slides up and down. Despite this, I managed to step the mast, but later when I was lowering the mast by walking it down, the tabernacle slid up and the mast fell onto the stern.
Is the tabernacle supposed to move in this way? I am hoping the answer is no, and that there is an easy way to fix the tabernacle so that it can't move. If the answer is yes, then I must say that it is a very poorly designed feature.
I'd appreciate any suggestions. Thanks.
