Bad Luck with Swedish Ralph Osborn Koster

Hello all,

Summer 2010 I was here a lot asking for advice and probably some of you remember. After a long yourney I found my boat and it seemed to be in an extremely good condition. How the can eyes can be fooled!

Under this link I have placed a range of galleries about the boat.

Index of /01Images/Sweden-Sailing-Boats/2010/Koster-project-web

01-The-Boat/ = about the boat
02-Hull/ = the hull, which seems to be OK, even after checking and knocking on the entire hull.

The boat was all it's live on the Swedish west coats in salt sea water. I took it half august 2010 to the Swedish east Coast, which is a lot less salty. (Baltic sea) and took it out of the water in october 2010 before the winter.

When i took it out of the water, we presure washed the hull and a little chip broke out of the hull.
This spring I decided to inspect the wood around that area and to my horror to find out that I have wood rot in the boat hull.

How is it possible to get wood rot in a mahogany hull, which was all it's live in salty sea water?

see here this gallery;

Koster close-ups


For me a big mystery.


Anyway,

last year many forum members adviced my to lower the keel and to inspect the keel botls.
It's now going to be not only inspecting the keel bots but all wood as well.

Hope I cam afford this fun.

Definitely not I was hoping for.

Any feedback welcome


Udo

Re: Bad Luck? with my Swedish Ralph Osborn Koster

it is quite possible to get rot due to electrolysis from the fasteners,mahogany and oak suffer from this a lot.

Re: Bad Luck? with my Swedish Ralph Osborn Koster

Beauty of a boat. But all that she is is what makes her hard to maintain. Best of luck, she is a really pretty boat.

There should be a few really good wood boat builders in Sweden. A bit costly but if it's done right it is worth the cash.

Did the previous owner know about this but not tell you? I know "Buyer Beware" but where I live there are some laws about "discovery" and hiding major flaws.

Re: Bad Luck? with my Swedish Ralph Osborn Koster

The seller told me clear that the boat was completely free of any woodrot, though told me that the last time he scraped the hull below the waterline 10 years ago and advice me to do so again in order to check the condition of the boat.

But as you can see in some of the earlier images I made last summer, the boat looked oK. I knocked on many places and initially could not find any worrying things till I pressure washed the boat and a little wood chip broke out of the hull.

That was the start of the discovery.

Re: Bad Luck? with my Swedish Ralph Osborn Koster

What is the grey material covering the wood planks below the waterline? If you say it's antifouling paint, I'm asking myself why don't I see the caulk lines showing through the paint? I've never seen a carvel planked hull not show the plank or caulk lines. Is it possible the boat has been glassed over wood or epoxy coated?

Hello Chris,

This boat has definitely not been glassed over. With a simple sharp scraper it's easy for me the scrape of the paint. However, the planks are very tight on this boat. During the hot summer, we had last year, the boat was continuously unused in the harbour and the freeboards above the waterline did show up no gaps at all. I can see the planks, and here on image 10 you can see a caulk line:

Not to belabour a point but, a professional survey would have found this.

Don 1500 is so right about the survey. But she is a beauty. Hope all works out for you.

Re: Bad Luck with Swedish Ralph Osborn Koster

It's not fairing putty many European bats that are carvel planked are built tight seamed, which is an art form in itself. the plank edges are planed to fit tight (no day light) either flat planed with the edge changing bevel as the run on the hull changes or they are planed concave edge to convex edge and then fastened to the ribs.

Yep you are right, but when I had an expert checking out another boat, i thought he would miss as many places as I could miss, also experts are not a guarantee.

Indeed, carvel planked, very tight seamed. edges planed to fit tight.

Even during the hot summer last year not a single place where i could see light in between the planks in the freeboard above the waterline,

No glue used, just tight seamed.
