Re: Irwin 1975 24 10/4 opinions, info

I sailed one a couple of times in the early 80's on the Chesapeake and was very impressed with her roominess and how well she sailed and handled in light winds. I remember that the centerboard pendant broke...can't recall much else but it is a compromised design in many respects. If you want a similar LOA boat that also has a lot of room consider the Nonsuch 26--very different from the Irwin 10/4 in many respects but similar in terms of room and beam.

The pin holding the center board on my Irwin 10/4 looks pretty shot anyone have any experience with this kind of thing? How is it held in? If I tap it through should I maybe replace it with stainless rod with threads on both ends? Roger

Re: Irwin 1975 24 10/4 opinions, info

I had my centerboard off maybe ten years ago. It's just that stainless steel pivot rod that is epoxied into the leading edge of the keel. Mine had worked through the fiberglass on one side so no telling how long it would have been before the pivot rod wiggled out completely and the centerboard dropped out. I tapped it back in with a hammer and epoxied a flat washer on the end of the pivot rod to give it something to push against. That was a couple haul outs ago and it seemed to be holding.

If you could find a rod that was threaded on just the ends that would probably work. I was thinking at the time that a long smooth shaft bolt would also work. I wouldn't put a nut on the other end. Just epoxy it in and the bolt head would give the fiberglass a little purchase to grab on to. There isn't much weight on that centerboard, so that shouldn't be an issue.

I guess the other question is if stainless is the right metal. I understand stainless isn't good imbedded in fiberglass as it can't get oxygen. Having said that, mine didn't look bad after 30 years. Maybe it isn't stainless? Don't know.

Rob,
I took your advice and after a new bow sprit, 1,500$ on 8 hp yanmar repair, paint everywhere port lights and a trip to Ocrocoke NC for a race that got canceled 1/2 way due to lighting wow what humidity great time though. Now I'm having the yard do the rest, stuffing boxes and some pretty rusty pullyes to the center board with luck we may just sail this year. This badly neglected boat has been quite a challenge . With lives curve balls thrown in. I hope we can keep in touch I've read your post a number of times it's the best info I have on this boat I really have great plans for summer fun on her. We sail great and little Peconic mostly. I'll moor the a few hundred feet from where Einstien kept his boat when he summered in Cutchogue. Hope you don't mind if we have a few more questions when we actually get in the water. Have a great summer, Roger

Has anyone owning an Irwin 10/4 had a problem with the center of the mast moving forward and aft when motoring into a head sea? I notice that there is only a single lower shroud! I had a Columbia Challenger sloop years ago that also came with a single lower shroud. When motoring into a head sea, the middle of the mast would move forward and back! I subsequently installed double lowers.

Rudy, I haven't noticed that on mine, though maybe I just haven't known to look. The mast is pretty substantial compared to some other 25 footers I've looked at. I think double lowers wouldn't be that hard to do and probably a smart upgrade. We had a 10/4 at our marine lose its mast during a hurricane when the steel I-beam the shrouds attach to gave way. That I beam is susceptible to rust and not easily examined. So lowers straight through the deck to each of the bulkheads would take some of the stress off that I beam.

A removable baby stay would be a more logical, cheaper and simpler way to stiffen up single lowers than changing to double lowers. It can be released from the deck and held at the mast until it is needed.

I, myself, personally intend to continue being outspoken and opinionated, intolerant of all fanatics, fools and ignoramuses, deeply suspicious of all those who have "found the answer" and on my bad days, downright rude.

Thanks for your input, Rob. We are thinking along similar lines.

Rudy

To the person who suggested a "baby" stay that could be removed and used only when needed, that sounds like a kind of "running" stay to me which would be rather cumbersome, in my opinion.
