What gear does Aleksey Nazarov recommend for maintaining a sailboat at sea?

The available content does not list specific gear recommendations for maintaining a sailboat at sea.

Based on general offshore-sailing practice, would suggest at least:

1. Basic and advanced tool kit (wrenches, multimeter, crimpers, spare fasteners)
2. Rigging spares (shackles, blocks, lashings, spare halyard)
3. Engine spares (impellers, fuel filters, belts, oil)
4. Sail repair kit (heavy needle, thread, tape, patches)
5. Electrical spares (fuses, connections, spare nav lights)

Are you asking about bluewater crossings like the Pacific, or shorter coastal trips?
