Anchor windlass wiring

[properjob]

The factory installed windlass on my catamaran has its breaker in the neg line. Why ?

I seem to remember that the BSS scheme required it that way, but why ?

Surely if the breaker were to trip it would leave all of the windlass wiring live with the remote possibility of a obscure return path to the neg terminal on the battery, which would mean that the windlass installation would not be fused.

Just wired up an electric winch(Lofrans) and the circuit drawing shows 100amp breaker in +ve line.

Not sure about your specific wiring, but its generally a good idea to disconnect the negative side of the winch if its it electrical contact with the chain when not in use, otherwise if at anchor for a while the chain can act as a big anode, there is at least one confirmed instance of this happening where it caused the chain to fail whilst at anchor. That said I would personally do that with an isolator switch not the greaker so maybe not appliocable in ur case
