A Sailor's Home in Winter

During winter I try to remove from Mekicevica all that can get damage by cold or damp and bring it home. The house and the garage get filled with boat bits and I wonder how does so much stuff fit in a 19 foot-boat. And this does not include the mainsail (at the sailmaker for small repairs) and the motor (being serviced).

What do owners of big boats do?
