Rolf,
Yes it is the Zen concept that turns this into great therapy.
"Wash the dishes for the sake of washing the dishes not for the sake of getting them clean."
"Fit the plank for the sake of fitting the plank no for the sake of building a boat."

To this end, if you have the space, maybe build one large project may be better than a small project each winter.

I have got a lot better at fairing since I built the Alfresco 920 hulls. So much water has gone under the bridge in the last 15 yrs. I would love to build another cedar strip boat.

Each to his own.

Regards,
Phill
