[You both are saying the same thing.]

You are absolutely right. I (mis)read his post three times before answering and still got it wrong. Thanks for the correction. I had this fight with the yard last fall and couldn't see what he was actually saying.

all the weight should be on the front of the keel only.

blocked with.... 25% of the weight on the nose of the keel. 

Mark,
You didn't say what % of weight should be on pads vs the keel, but, above, parsing out the pertinent information ... You both are saying the same thing. 

Weight should be supported at the nose (ie., forward part of) the keel. ***

I trust that you are not saying there should be no weight on pads (be it jack stands or a cradle)???

PS: ***Do not read into this I buy into CTY's fantasy explanation of what causes a smile.

I'm getting what looks like gelcoat chipping on the bottom of the keel. Five years ago, the PO shell blasted the bottom and coated with two coats of west system barrier coat. The yard looked at the bottom of my keel yesterday and said they never did the bottom of the wing. Offered to put me in the slings for a day or two in July for me to grind it off and barrier coat the bottom of the keel. Sounded more than fair. I mean, I'm sure they're going to charge me, but they said it would just cover their costs.

Is there anything I'm missing from this? Anyone do this job and found it to be more onerous than they thought?

Ron,

I'm not one to disagree with you and your experience, but the mechanical drawing from Catalina shows blocking only on the front of the wing keel. Mine is a Mk.II, so there might be a difference, but for Mk.II wing keels, all the weight should be on the front of the keel only. Next time I'm down at the boat, I'll take a picture.

dan : Disagree with you on the cause of the smile.  I talked to the factory many years ago and they recommend that the boat be blocked with 75% of the weight on the jack stands/cradle and 25% of the weight on the nose of the keel.  Also VERY important to get the jack stand pads on the bulkhead!!

A few thoughts

If you go with a "triducer" (depth, speed, temperature) you will only need one through-hull. Resulting in you having to seal up one of your through-hulls and probably replace/alter the remaining one to accommodate the triducer's size.

I can verify this. I bought the Raymarine all in box set with wind, knot meter, depth and temperature and a couple of i70 displays. All was installed except for the triducer. It was a DST810 and does not fit in the same size through hull. I was going to leave the old depth sounder in there, rather than doing all that glass work.

In retrospect, I would have bought the B&G for all the great sailing features it has. Especially when paired with one of their chartplotters.

Our C28 (Also an M25XPB) had black soot in the engine compartment in line with the alternator. Turns out it was he graphite from the brushes.YMMV

Do you mean Sailrite? I couldn't find anything on Sailtite, but I'm not a great googler.

Check on the Sailtite website and/or call them. They have some fast draining (open cell) for cockpit cushions, in three different firmnesses.

Jim,

Thanks for the response. I found your posts suggesting this and I think it would be a great solution for riding on the bow. The admiral wants the full length cushions and Mola Mola already has the snaps to hold them in place so they won't fly around.

We just use the folding seats with the adjustable backs. 

That's what I use.  I would only recommend the Sport-a-seat.   My Sport-a-seats are 15 years old and still good.  Friends that bought knock offs were soon disappointed with the frame/hinge breaking.   
Having said that, cushions with closed cell foam with a mesh cover are good in the rain and dry quickly but are not as comfortable to me.

It looks like it's been a few years since this was discussed the last time, so I figured I would bring it up here. Especially since it looks like Bottom Siders is out of business

Is there a consensus on which is better in the cockpit, closed cell or open cell foam cushions? We like to use our cushions both sailing and at rest. I was originally looking at Catalina Direct, but as I did more research, I found tons more manufacturers... C Cushions, Catalina Owners, Foam Order, and The Foam Shop, just to name a few.

They all seem to have the same types of cushions, just different options built around two themes: Vinyl and open cell foam, or Sunbrella and closed cell foam. 

Anyone have any thoughts about the manufacturers or whether open or closed cell is the right choice?

I would like to know the correct setting for the M35BC. When we bought Mola Mola, it was way off. I finally got a tach on it and got it dialed in, but now I notice that the hour meter is running 2x faster than it should be.

sounds like you need a second opinion.

Years back, I was taking slo-mo video of my 1991 C28 engine and noticed not only some cracking, but also how much they bent while the motor was running. (it was 25 years old at the time) Catalina's answer? "They do that, nothing to worry about"

I guess the only way to know is to get a second opinion

The survey was done for a buyer who has made an offer for this boat which is for sale.

I was talking this off today because the caulk looked like it could be leaking and, well I guess I was right. Taking this piece off showed significant delamination on the starboard side and minor delamination on the port side. It would seem that the caulk under the screeds failed and let water past. Sounding it the best I could, it seems like on the stbd side, it goes about 2" in and on the port side, maybe 3/4".

Questions? Since this isn't structural, I think I can just fill it with penetrating epoxy, clamp it, and call it a day. Is that right? I almost feel like another layer of glass could help, but I don't know that I want to get that deep into it.

Sounding the deck under this cover didn't reveal anything interesting and sounded like pretty solid glass underneath. I may take a bent nail and fill it with epox just to make sure. Is there anything else I need to do?

The guy in the J28 next door said to dry it out, but it's been sitting all winter. I can't imagine there's any moisture left, other than what's in the air.

Hmmm... looks more like a refit. More details to come...

Wow! Well, I almost have the whole thing traced through. The depth sounder and knot log go:

• To port and aft, like I guessed, into the port hanging locker.
• From there, they go, like KeelsonGraham mentioned into the space behind the port settee. There's a glassed in PVC pipe that carries these wires aft.
• Then they exit that PVC towards the aft end of the port settee and go up into the electrical compartment. There's a piece of trim that hangs down from the top of the electrical compartment. All of the wires are tucked behind this trim.
• They travel aft all the way across the electrical compartment to... somewhere. I can't figure out where they go. I've removed the trim in the head, but not the cabinet yet.
• From there, they appear in the aft cockpit locker and traverse the back of that

[li] Then they *appear* to go into the aft port locker and then *probably* into the posts for the Navpod
[/li][/list]     

I will update this as I get more information and continue to trace these wires. The weird thing about the routing through the head is that I can't see any wires going into the head...it almost looks like there's possibly a space behind the head??? Anyway, I'll leave this as a reference to anyone else trying this. I'm sure that I'll need to update this once I actually run the cable rather than just trying to trace it.

Mark

On our boat, both of these instruments are just forward of the bottom compartment in the v-berth. These wires go to port and disappear behind an insert. I can't tell where they go. Does anyone else have this setup? Any idea where they go on the port side of the boat?

I mean, logic would say that the wires are behind the port settee, nav station, hanging locker, and head, but I'm trying to pull new wires and want to get an idea of what I'm in for before I start it.

Thanks for your help!

Are there any references on how to grease them?

Guys : The Marelon valves are sturdy, but it is one of those items that need to be "greased" every year; so that they stay easily tunable!!
