Re: [Cal_Boats] Cal28 Chainplate material?

I'm not sure the material. I thought the originals were bronze. I've attached pictures of my originals and also the new plates that I machined out of aluminum bronze. The shots taken above deck are of the new chainplates are have started to rust. I don't think I would recommend aluminum bronze at this point. Is this sarafina from crusiersforum? If you have time, could you show me some pictures of the bag you made for your outboard in well? and maybe in place as well?

Missed the last one! This is one of the new chainplates out of aluminum bronze, about a year installed. About time I get to switching those stainless screws to bronze!

My Cal 28 ( no 155) has stainless steel chainplates. I also had big water intrusion which required new bulkhead. I will up load pictures soon. Geo. Barlow

Hi, Can't see the pics for some reason but thanks for trying : -( I am she, and I used a big dry sack for the prop protection, one I picked up at a marine swap meet. Nothing custom at all. I jockey it down beside the outboard in the well and then, using lines tied to the straps on the side and a broom handle, open it up around the prop and pull it up. Once I have the edge of the bag above the water line I stick a big manual pump in and pump out the water until she is dry inside. Stays dry all during the off season no problem. I don't bother with it if we are sailing often, but more than a week sitting around and it is worth it. That modification is neat but I do not believe the C28 lazarette is deep enough to the transom to accommodate a tilt inside it. --- In Ca… [at] yahoogroups.com, Adam Thorp <thorpydo@...> wrote: > > I'm not sure the material.

Just a question as I dont know the boat but.....would it not be simpler to move the chainplates to the exterior of the hull as they do with long distance cruising vessels. Its really a questions for a designer as I dont know if the hull can take the stress. But it sure would remove all the water penetration issues. Then again, it may interfere with the jibs and jib sheets pending on what size you use. Just an avenue of investigation. Best regards /ch

To avoid having to do the maintenance of undoing a couple of screws, scraping out some old caulking and putting in new once every 5-15 years you want to do how much work? If there are bolts holding the plates on there are water penetration issues no matter where they are. Admittedly you don't care as much if it's leaking through your solid fiberglass hull than onto wood bulkheads or deck core. Some people say that the only good cruising boat is one that has a full keel, outboard shrouds, etc, but there are many (if not most now) boats that are good cruising boats that sail much better than the old designs.

It was just a question in case the bulkheads were gone...:) Many boats are good cruising boats. Few are good bluewater boats that you can spend years on in all kinds of weather. In the CAL collection there are a couple that are outstanding. Popping on an external set of chain plates takes what less then a day if you have the parts, do it yourself, and do one at a time. Its the removal of the other stuff and sealing the deck that takes time.

On my ancient Cal 24 the straps are bronze. I'd like to think of them as "mystery metal".

Don't have water penetration issues around the plates, so I don't see any reason to go to the bother. They have remained dry, no water marks at all, or soft spots above. And I have seen plenty of cruisers with bulkhead chainplates. Wouldn't have thought of that as a bluewater designator necessarily... I suspect at least on the 28 the placement and sail paths might be an issue. The PO moved all the stanchions inboard about 8", clearly to reduce friction with the sails and lines. Moving the stays outboard would be counter to that thought. --- In Ca… [at] yahoogroups.com, chris123 <chris.herrnberger@...> wrote: > > Just a question as I dont know the boat but.....would it not be > simpler to move the chainplates to the exterior of the hull as they do > with long distance cruising vessels.
