Hi Keith, This is a well known 376 problem, the mast compression support was cast iron and it rusts. The solution is , rig down, remove joinery and replace the mast support, the bulkhead bonding needs to be checked as well. Hope this helps, not a DIY project I’m afraid, Regards, John

Hi,
I don't think Moody ever used cast iron for a compression post, they used a mild steel tube with mild steeel plates welded on for the top and bottom ends. It also rusts. Greater problems with the mast support system arise from the timber blocks , one on which the compression post is mounted and the other in the deck between the top of the compression post and the mast step. In both cases, water can get into them and start rot with the consequence that the timber can no ;longer bear the load and gets squashed thinner. In the case of the block in the deck. the issue often arises because the holes bored through it to pass cables below deck are not adequately sealed.
