I have a 1998 Catalina 28 MKII. This year for the first time I noticed some dripping on the rudder after taking the boat out of the water. I opened up the cover for the emergency tiller and found it was full of water. I always thought water drained from this area and have seen it do so in the past. Not so this year. The boat is on the hard on the south shore of Lake Ontario and subject to deep freezing and I would like to ensure that it drains properly and stays dry. Yes I can put antifreeze in the area and make sur eit is covered but it should drain. Any ideas on what might be ahppening? Thanks.
