Yes. But in a conventional carvel hull, the caulking absorbs the extra
dimension of the expanding wood.

WHAT ?????

It is my understanding that a carvel hull has a slight bevel on each plank,
so the planks only touch at the inside of the hull. The cotton used for
caulking is then driven about halfway in the seam, in order to form a sort
of watertight 'rope' slightly indenting the planksides.

Don't anyone in this forum have any hands-on experience ?
Caulking is done at the outher third of the seam and the seam is prepared
for caulking, ------- It's bloddy _not_ the damned caulking that make the
hull watertight when you build a cravel planked boat, as the bloody seams
are TIGHT even before the caulking is there.

Mmmm, I quote from the Boatbuilding Manual from Robert Steward:
"Carvel planking is usually made with the seams tight on the inside and open
on the outside to receive the cotton caulking, which makes the planking
watertight".

Bet you even think that caulking is just about banging in stuffing untill
the whole plank is forced to destroy the seams around and above, ------
seem
like you even mix two compleatly different technikes by talking about
caulking with Lapstrake building ; YOU DO NOT CAULK A LAPSTRAKE HULL,
unless
it's old and worn , unless the planks shuld have been replaced decades
ago,

Ehhrr, where exaclty was I referring to lapstake construction?

don't you Amature boatbuilders know the difference between Lapstrake and
Cravel ; then how the hell can you avoid to crack the plank edge if you
start caulking a Lapstrake hull -------- don't you se it, don't you even
know that you can destroy a lapstrake hull by caulking it ????

Well, at a boatbuilding school here in the Netherlands they build clinker
lapstrake hulls and they do put sikaflex between the strakes for caulking.
Nothing is destroyed by that.

Geez Per, why on earth ary you reacting so offensive????
