Wich way is the best to restore an old wooden hull ? Caulking or Splining ?
Boat is 35' long, hull is cedar over oak, very dry, fastening seems OK.

Depends on your goals, the boat, and your skills.

Grana was splined and epoxy coated within and without. A very good job that's held up for about 30 years now. I've seen bad jobs lucky to hold up 30 days, especially if there's water intrusion through a flaw.

The splining and epoxy treatment is far more costly to do and is justified more if you plan hard long sailing.

For more normal sailing or for 'historically accurate' restoration, caulk.

Thank you Ian

At this time I only plan normal sailing.
Is it necessary to coat with epoxy the outside and the inside of the boat ?

In word, yes. The idea of epoxy sealing is to keep water out of the wood. Only coating one side is like taking a walk in the rain with your raincoat on one arm and shoulder only.
