Decided it was time to fix the cabin top dribble down the compression post.

I'm logging the progress on my blog.

The cause of the dribble is definitely the degraded compound between the Mast base and the cabin top.

Good looking blog Paul! I didn't know you were towing with a smart car. Those diesels are tougher than I thought!

Thank you for sharing such detailed information. Can anyone tell me if an 88 25 would have the same post as well? I thought it was just a plate. I am preparing to lower the mast this summer and add a halyard plate under the mast step plate. I thought I knew what I was in for, but now am not sure. Just left my boat yesterday (4 hours away) so I can't go look until next weekend.

Erin, the C25 compression post setup is entirely different from the C250.

Others will chime in.

Paul,
Good post, made a comment on your other post about a bigger boat. When I did this I ran into some of the same things you did, but not the swirly things on the cabin top. Looks like someone was overzealous with their grinder or something?

I didn't know about butyl at the time, or I'd have used that instead of Life Seal. I still get an occasional drip down the compression post even after all the work to get it sealed up. Did you also epoxy seal the plywood in the post hole? At least on mine, I know the water can't get into the wood after I sealed it.

Erin,
I helped Alex (awetmore) drop his mast a couple of weekends ago on his '84 C-25. The mast is deck stepped, and as Paul said, completely different from our C-250's. I don't know whether an '88 is the same, but it probably is. Getting the halyard plate under the mast was relatively easy. He only had to drill one hole for his VHF coax access. The cleanup was pretty straight forward as well, a bit of scraping the old compound off and some minor sanding to clean it up. I think I have some pictures on my phone of his deck step that I can post.

Chris,
I doubt that Paul's SMART is a diesel, I don't think they import that version to the US. At least they didn't import them into the US when I was looking for a high mileage commuter a while back, although you could purchase them up in Canada. The gasoline version only got about 35 miles to the gallon as I remember (this was about five years ago). The diesel version gets something like 55 MPG if I remember correctly. I bought my Jetta TDI specifically because it got such great mileage. I get 43 MPG on the road and about 37 around town.

David is correct, the SMART car is not a diesel.

I did have to add weight up front to offset the hitch load though

Alistair (a friend who helped out) did need to file out two of the holes slightly to get them to align with the ones in the original deck plate. It wasn't major surgery though, and only took him a couple of minutes with an 8" round file. Drilling the hole for the VHF cable was a lot more work and would have benefit from a drill press.

The organizer plate is really nice, and I already have 3 lines running through it back to the cockpit (two halyards and the boom vang). The reefing lines, topping lift, and outhaul will probably head back that way too.

The only other helpful little advice is that a 2x4 (or other piece of scrap wood, maybe even a broom handle) is helpful for torquing the step from the fiberglass once you've removed the 4 bolts.
