I NEED EXPERT ADVICE!
I am aware of the work which will be involved with wooden boats, but I have a concern:
I am considering buying
a 24 ft Koster made in Sweden
is made of: Mahogany on oak (Carvel build)
The boat was kept in the same family
for many, many years ( around 25 years)
Under the waterline the boat is having a plastic / (according to the owner) a thick epoxy
coating and when I looked at it, feels like a thick flexible rubber coating. This was applied 15 years ago. The owner also told me that every year the upper edge along the waterline, needs to be checked, because the edge might loosen a little, just only a few mm. but needs to be re-glued with epoxy
glue in order to avoid this going any further.

This means, the hull
under the waterline is completely sealed and should not let any water
After scraping the hull above the waterline (the freeboards), the owner applied a varnish
called Coelan (one of the most expensive on the market) which is a Polyurethane varnish
. Of course the inside of the hull is not varnished at all so the hull is able to breath.
With this type of carvel build boat, it's not unusual that in the beginning of the sailing season (after the winter) some water
will get through the freeboards when the wood is very dry. The owner told me that this is happening.
This is not my major concern!
is not self bailing. Any water from rain (fresh water) or (salt) water coming in whilst sailing flows via the drain holes in the cockpit
floor boards over the inside of the hull to the lowest part of the hull just above the keel
(Image 10 + 14) see link below to my gallery)
The boat is having (of course) a manual bilge pump
and an electrical bilge pump
, from which the last one will be automatically activated the moment water is detected above the keel
on the inside of the boat.
I know, it's normal for wooden boats to have water in this place. The boat is in the baltic
(Stockholm area) , so it is in (cold) salt water
(but the baltic
is not as salty as the Atlantic or North sea!)
My Major concern:
Since the boat is completely sealed on the outside and fresh water is able to get inside when it rains, unless I use a cover for the cockpit, I just wonder if this part is not going to give me in the future major worries. But have to say: after 15 years with the coating on the outside, nothing seems to be rot
I checked all the wood on the inside. All seems to be OK, except a tiny piece of wood supporting the floor boards, which feels soft, but this part is above the water, when there is water inside the hull, above the keel.
At the very bottom above the keel (deepest point) below the cabin
floor boards, where usually some water is, also the wood still feels very hard, but some of the red-lead paint
is peeling off and bare wood from the hull is exposed, so this part of the hull will be easily soaked with a combination of slightly salt water
from the baltic (coming in during sailing via cockpit and freeboards) and fresh rain water.
Is this really going to be a main concern? Or what do I need to do?
Have to get the boat back on the land, scrape all the paint
on the inside of the bottom of the hull just above the keel away, let it dry for a whole winter season and paint it next spring with red-lead paint, or apply an epoxy?
Or could I use the boat this summer season for sailing and tackle the issue after?
Or not to buy the boat at all?

many thanks in advance for any advice!
