I hope you find this interesting. Today we took my boat to the loacal Catalina dealer's and met the fellow from my neighborhood that has a soda blasting rig. It took 2 hours to blast and another 30 minutes to spray it down and generally finish the job. The link to the pictures is:

We are going to do a little fairing on the keel but not much. We also have a few blisters to mess with but the majority of the blisters that turned up (none were visable when the paint was on, I thought I had a blisterless boat) I will ignore. I will put VC-17 on because of the ease of maintaining it from now on.

Why not do an epoxy job on her now that she's all cleaned up?

That soda blaster is neat... I WANT ONE. No, I NEED ONE.

The position of that front strap sure scared me... did you have a safety line on it so it couldn't slide?

They have put straps in that position for 20 years, scares the hell out of me too. The picture of the guy on the ladder is him getting on the boat with the straps like that. He raises the boat with a manual hoist and does it from the cabin top. He also lowered and raised the keel while it was up there. He did have a line on the front strap but I think it goes the wrong direction. It sure would not work on a Beneteau.
Dave, (the guy on the ladder) said that the problem with barrier coats on old boats like ours is that the chemistry of blister generation is probably already going on and a barrier coat would make it hard to manage the occational large blister that needs tending to as it shows up. It is an interesting point.

Wish we could do that kind of thing here in Washington. As it is now we would be hit with a 25,000 dollar fine from the E.P.A. I cant even sand without an 8 hole orbital sander hooked to a double filtation 5Hp vac and the boat must be tented.

Vote Republican, we did. Seriously, you would think that after Mt. St. Helens people up there would quit worrying about the polution of people. Mother nature can smack us down anytime she wants and we are not going to smack her down. That latex paint was three years old and any toxins had leached out.

two questions

How will the steel keel react to the alkalinity of the soda blasting?

Will soda blasting remove some of the dry skin from my face?

<hr height="1" noshade id="quote"></blockquote id="quote">

The soda residue will be washed off with simple soap and water. We would have done it yesterday but there was just too much blue goo under the boat to want to work under it. We are letting the area dry today and will clean the boat Monday before we take to the inside lift. In the pictures you may have noticed there is a car wash next door, I may even take it through there. As we fair the keel, glass it and add the hula it will become a cast-iron fortress of solitude.

I wear a CPAP mask at night, (obesity sucks) and the area where it sits gets dry. When I got home last night it seemed irritated, I put some Neosporan on it and it burned when I touched it. I think the baking soda dust had been working on it all afternoon.

I think the most amazing thing to see yesterday was there was no difference in the technique for blasting the keel and the fiberglass. The dealer, (Ed) his son, (Dave) and I, (me) all saw no evidennce of any damage ay all to the gelcoat. Dave said it was in better condition that if we had sanded or if we had used a chemical strip.

Hey Frank
Actually, for the dry skin on my face is caused by seborrheic (spelling?) dermatitis. I use Aclovate Cream 0.05%. It is a topical steroid. Prescription. works like a charm. The winter wind is what causes it, never get it in summer.

I understand about using a CPAP mask. It is sometimes a challange for me to intubate someone who has to use one, and then to ventilate someone who isn't intubated and obstructing.

Good luck.

By the way, nice job on the boat. Are you going to drop the keel?

In the keel ball thread I have a picture of the pin area and I do not think so. I am wrestling the demons who want me to order the wing. Let’s see; $200 to fair/paint/rebuild or $2500 to retro fit the wing. Damn you demons, never a moments peace.

Dropping the head of the keel should be pretty darn easy at this stage in the game... I estimate it might take an hour using the 'all-thread' method. Then you could epoxy coat the entire keel.

Freshwater sailor? Heck, take care of the cable, fittings and ball... I wouldn't worry about going to the wing keel in your venue.

My own plans on a wing conversion are based on finding out how the family likes cruising.

First trip to Clear Lake (CA) for a 3 or 4 day 'cruise'. If successful, then off the San Juans for 2 or 3 weeks... If they like that, I will probably convert to a wing keel before taking the boat to the Sea of Cortez in 2005. (gawd, that sounds scary... 2005)

I have to say. We bought our C25 this summer and we have the same exact plans with the exception of our first cruise being in S. Oregon on different lakes (all went well). We drove down to Baja last christmas and after seeing the sailboats anchored in Bahia Conception, then in Vancouver B.C. / Seattle this summer, it was all over.

See ya out there,

How much energy does it take to destroy the environment?

one Watt.

I have a T-Shirt with a bunch of people doing the lemming walk off a cliff the caption reads. "Vote consertive, look what it did to the Germans."

Other than that, cool lift too. I want one of those in my back yard too. What was the cost of the soda bath?

Oh you silly kids.

The lift is handy. We are moving the boat to an inside lift later this week. I am putting an Interlux 2000 barrier coat on her. Today when I went out to look at the hull again, (now that it is dry) I see the 20 odd years of bottom maintenance on the hull. Lots of pits and tiny blisters and voids and chips and sanded through places. Just generally 20 odd years of bottom maintenance. I will post some pits tomorrow. The blast job will sell for about $400-$450 here in Wichita. It is such a good prep for the barrier coat that it makes the barrier coat a cheaper event. It will be right at a grand with the blast, barrier coat and VC-17. I will have a fast bottom that will be easy to maintain for the rest of the boats life.

Exactly . . . and you don't even need a power washer to clean the bottom at season's end . . . if your season ends that is.

Is there anything quite as nice as hired help

Interlux 2000

We tried a different barrier coat on my rudder, I forget the name. Dave at the dealer said it turn too quick to use on a bottom and he was glad that he had tried it on a couple of rudders.

Hmmmmmmm... Out here, they sprayed for mosquitoes carrying West Nile, and ended up killing all the lobsters in Long Island Sound--ALL of them. Turns out lobsters are not too loosely related to mosquitoes (look at pictures the same size of each). One benefit: hardly any lobster pot warps to catch on your rudder any more...

We are most certainly capable of smacking down Mother Nature, and have done it in many ways in many places. She's getting back up in some places like Lake Erie, but more slowly in others, like the Hudson River and Long Island Sound. Humans are, as I see it, the most destructive infestation in the history of the earth.

BTW, that strap position scared me, too. I don't get the point of it.

They do it to minimize the area under a strap. The point is, there is less bottom covered by strap. For the soda blast it left less hand sanding, for the barrier coat it leaves less area to feather in. They have always done this, I made sure the boat is very empty before I took it to them. When I had my Merit, it was lifted from a single cable suspended from the hoist to a keel bolt with an eye on it. It was great for hull exposure but the stern and bow of a hull can droop when hung from a single point. Bottom line, I'm glad our boats are so well built and strong.

Forgive me for keeping this updated, I hope people find it interesting. Since I am spending my children's inheritance, I find it great theater.
I found these nylon bushings at my pin today, can you see it? They seem like a good thing to find.

This picture shows how little is left to be done at the bow, He leaves enough at the stern to use one gallon of the Interlux 2000 to finish the job.

I wish I could hang my boat keel down in my garage!
