Arguably, I'm spoiled. On my C28, I had a M25XPB and on the C34 we have the M35BC. In both cases, I've appreciated the boat speed we were able to maintain in 20kts of headwind with the sea state to go along with it. In both cases, we happily clipped along at 4.5-5kts. I attributed it to both boats being slightly overpowered for their size and weight. I wonder how true that is, though. Of course we're talking theoretically, but I wonder how much different it would be with the M25 in the C34.

I think that the only way you will really know the answer to this question is if you have a mechanical engineering friend. Knowing that type, turn it into some kind of bet and offer them a case of their favorite beverage so they do a "Finite element analysis" of the keel/hull joint blocked in the front or blocked fore and aft.

Logic dictates that the bolt isn't stretching, but the piece of keel that sticks out forward of the forward most keel bolt can bend. I'm not saying it does bend, I'm saying it "could". FEA (finite element analysis) would tell you exactly how much force you would need to create a "smile"

that's a good suggestion, and one I'm going to do at the end of July. For now, I just slapped some antifouling as best as I could and will deal with it then. This should be sufficient until then, no?

Quote from: Ron Hill on April 26, 2024, 09:25:07 AMMark : Here is what I do before the spring splash. Late in the day I have the yard lift Apache up so I can examine and bottom paint the underside of the wing.  Then the boat hangs in the slings there overnight and lets the paint dry. I'm the first splash the next AM.  Works well.

Good question. Only that the rest of the hull has it. I hadn't even thought about doing something different. If primer is all that's needed than great! But I wonder, then, why did Catalina gelcoat the keel?

Quote from: KWKloeber on April 24, 2024, 07:28:10 PMHonest question, inquiring minds want to know.

What's the purpose of paying to epoxy-barrier-coat a lead keel? 
A barrier coat is to prevent blisters from forming on a polyester-fiberglas hull.

Isn't a good paint primer enough on a lead keel?

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.

Quote from: girmann on April 24, 2024, 04:58:27 PMall the weight should be on the front of the keel only.

Quote from: Ron Hill on March 17, 2024, 03:23:06 PMblocked with.... 25% of the weight on the nose of the keel. 

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?

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.


Quote from: Ron Hill on March 17, 2024, 03:23:06 PMdan : 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!!

Quote from: Noah on January 10, 2024, 08:59:24 AMIf 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.

Quote from: Noah on July 05, 2023, 12:55:18 PM
Check on the Sailtite website and/or call them. They have some fast draining (open cell) for cockpit cushions, in three different firmnesses.

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.

QuoteWe 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.

Mola Mola #1488
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.
