      A Few Simple Rules   05/22/2017

      Sailing Anarchy is a very lightly moderated site. This is by design, to afford a more free atmosphere for discussion. There are plenty of sailing forums you can go to where swearing isn't allowed, confrontation is squelched and, and you can have a moderator finger-wag at you for your attitude. SA tries to avoid that and allow for more adult behavior without moderators editing your posts and whacking knuckles with rulers. We don't have a long list of published "thou shalt nots" either, and this is by design. Too many absolute rules paints us into too many corners. So check the Terms of Service - there IS language there about certain types of behavior that is not permitted. We interpret that lightly and permit a lot of latitude, but we DO reserve the right to take action when something is too extreme to tolerate (too racist, graphic, violent, misogynistic, etc.). Yes, that is subjective, but it allows us discretion. Avoiding a laundry list of rules allows for freedom; don't abuse it. However there ARE a few basic rules that will earn you a suspension, and apparently a brief refresher is in order. 1) Allegations of pedophilia - there is no tolerance for this. So if you make allegations, jokes, innuendo or suggestions about child molestation, child pornography, abuse or inappropriate behavior with minors etc. about someone on this board you will get a time out. This is pretty much automatic; this behavior can have real world effect and is not acceptable. Obviously the subject is not banned when discussion of it is apropos, e.g. talking about an item in the news for instance. But allegations or references directed at or about another poster is verboten. 2) Outing people - providing real world identifiable information about users on the forums who prefer to remain anonymous. Yes, some of us post with our real names - not a problem to use them. However many do NOT, and if you find out someone's name keep it to yourself, first or last. This also goes for other identifying information too - employer information etc. You don't need too many pieces of data to figure out who someone really is these days. Depending on severity you might get anything from a scolding to a suspension - so don't do it. I know it can be confusing sometimes for newcomers, as SA has been around almost twenty years and there are some people that throw their real names around and their current Display Name may not match the name they have out in the public. But if in doubt, you don't want to accidentally out some one so use caution, even if it's a personal friend of yours in real life. 3) Posting While Suspended - If you've earned a timeout (these are fairly rare and hard to get), please observe the suspension. If you create a new account (a "Sock Puppet") and return to the forums to post with it before your suspension is up you WILL get more time added to your original suspension and lose your Socks. This behavior may result a permanent ban, since it shows you have zero respect for the few rules we have and the moderating team that is tasked with supporting them. Check the Terms of Service you agreed to; they apply to the individual agreeing, not the account you created, so don't try to Sea Lawyer us if you get caught. Just don't do it. Those are the three that will almost certainly get you into some trouble. IF YOU SEE SOMEONE DO ONE OF THESE THINGS, please do the following: Refrain from quoting the offending text, it makes the thread cleanup a pain in the rear Press the Report button; it is by far the best way to notify Admins as we will get e-mails. Calling out for Admins in the middle of threads, sending us PM's, etc. - there is no guarantee we will get those in a timely fashion. There are multiple Moderators in multiple time zones around the world, and anyone one of us can handle the Report and all of us will be notified about it. But if you PM one Mod directly and he's off line, the problem will get dealt with much more slowly. Other behaviors that you might want to think twice before doing include: Intentionally disrupting threads and discussions repeatedly. Off topic/content free trolling in threads to disrupt dialog Stalking users around the forums with the intent to disrupt content and discussion Repeated posting of overly graphic or scatological porn content. There are plenty web sites for you to get your freak on, don't do it here. And a brief note to Newbies... No, we will not ban people or censor them for dropping F-bombs on you, using foul language, etc. so please don't report it when one of our members gives you a greeting you may find shocking. We do our best not to censor content here and playing swearword police is not in our job descriptions. Sailing Anarchy is more like a bar than a classroom, so handle it like you would meeting someone a little coarse - don't look for the teacher. Thanks.

Bulkhead repairs

16 posts in this topic

Anyone have a good idea/estimate of how much bulkhead repairs cost?

 

Our used J22 (1987 #635) arrived yesterday and after thorough inspection with some friends at the new club, we've been advised that we need to have the starboard side bulkhead inspected and repaired/replaced. The wood is very soft (mostly at the edges and not around the bolts, but that probably doesn't matter).

 

Gonna make some calls tomorrow, but wondering if anyone has a ballpark idea or has dealt with this before.

 

Thanks!

We had that issue on our J22 right at where the chainplate met the deck. recall it was about $500-1000 based on condition.

though I'm dating myself here. I last owned our J22 in about 1996 or so.

On a 24, the bulkhead kit from Waterline was about $400, did the tearout myself, had the installation done for about $500.

Bulkheads in the these boats are plywood. Get a sheet of plywood from Lowes, $30. Cut it, epoxy it, glass it in. Pretty simple.

But get Marine Plywood the difference is there are no voids in the Marine grade

cut out old bulkhead with fein saw (use for pattern) use marine ply. measure to make sure your chainplates are equal (ussually not) grind back 3-4" on both sides.

install new epoxied on all sides bulkhead. do fillets to hold tabbing nicely Tab in with 2 layers 1708 cloth. 8" and 6" or so. buy a mask, suits, and a box of rubber gloves etc.Total parts about 3-400

 

3/4" marine ply 200 ish i use okoume 4X8

glass maybe 40

epoxy a bit more than a qt. 45

 

rolling on a coat or two of an epoxy primer makes it look better

 

your aft bulkhead is likely toast as well

assume a repair at the chainplates too.

Bought a 1987 J22 2 years ago. All the bulkheads were toast and looked like the pictures that are provided. I replaced everything myself with 3/4" okoume. Really nice material and very attractive finish. Boat is now super solid. Use Epoxy Resin and not Polyester Resin. The materials will cost about $300.00. Replace them all. Since you're upside down, it would behoove you to get this job done and over with. The boat will be good for another 20 years or so. Just keep the water from seeping through the deck at the chainplates and keep the interior as dry as possible. A deck fan is recommended. I am 72 years old, so you should be able to do this job yourself. Or, buy a lot of beer and invite the crew for a party. Good luck, the boat is well worth it.

Thanks. Got an estimate of about $1400 average for the bulkhead repair. There is also some moisture around the chainplates. Probably need to remove about 3-4 inches at $350 per side. So about $2100.

 

I;d love to do this stuff myself and will look at some sites, but i'm also very nervous about it!!

indeed. one J/22 pro told us to remove and reseat the chainplates every 4-5 years or so.

Agreed.

 

I did my tearout in about 3 hours by using a sharp chisel and cutting the tabbing all the way around then pulling out the wood.

chainplates are easy. first remove the chainplates and set aside. bend a nail a little stick it is a drill and drill between the deck and inside layer of fiberglass. The rotton/wet core is typically black. Just bend the nail a little longer each pass until you are starting to dig out good core. Stop. Tape the back (Inside) thicken some West System and inject, it will seep into all the right areas and now you are water tight for the deck. drill out the slot for the chain plates, reinstall, use a good silicon, good to go.

DO NOT use Silicon on chainplates. Or most other boat places for that matter...

 

Try Sika 291

Lifechaulk

3M 4200

If you need to remove 3 - 4 inches per side, it will probably be closer to 6 inches for and aft. I doubt the nail in the drill trick will work for that. You should ask you repair guy what he plans to do to fix the problem. The most straightforward and accurate way to fix it is to take off the top non-skid layer of fiberglass and have a look at the core. You can use a dry wall cut out tool to cut some of the top layer of deck off, inspect the balsa core, cut out the soaked stuff and replace. Replacing balsa is easy. Just epoxy it in and then cover up with fiberglass. Many will say only cut from the bottom (e.g in the cabin), but it is really tough to inject epoxy and not have gravity take over this way. The downside with cutting the top layer is your repair will be obvious to the next buyer. (maybe that is not a bad thing).

 

For bulkhead repair, the estimate you got is pretty reasonable. You can do it yourself. It is pretty straight forward. Just get 4x8 3/4 inch MARINE plywood. You'll need to remove the benches and the chain plates and then carefully cut out the old bulkhead. You want to preserve it's shape so you can use it as a template for the replacement. It is a long weekend project, so if you don't have time, the $1400 is not a bad deal at all.
