Re: Cal 28 Teak Toe Rail
I have the same construction on my Cal 33-2. I think you are going to have a tough time finding an identical replacement. And it will be a huge job, requiring removal of the entire toerail, etc. You could certainly just reinstall the toerail with LIfecaulk or something similar in place of the gasket.
Are your sure that is where the water is coming from? Not from stanchion bases or other leaking fittings? You certainly don't want to go to all that trouble and find out its coming from somewhere else.
