Ahhh..doh!...thanks Apex :)

Well, depends on the hull material, one assumes steel. Also depends upon the Flag authority the boat is being designed too, and also whether local reg's are applicable too. However, all you 'should' need is just ventilation from the void, providing that there is no other source of ignition, such as oil, or flammable linings etc.

But, as noted if the local reg's of Flag state view the anchor eqpt as "safety" (it may then fall into another catagory) then it may require some discussions with the Flag state for clarification and/or dispensation. Also if there is any redundancy too, will affect the Flag state's views.

I would call an electric motor driving a hydraulic pump an ignition source.
The oil reservoir is in there as well.

what power is the motor, this defines the catagory?

I'll check but
1m long 500mm diameter 440v 3ph 60

The power, ie in kW...since the size (in kW) dictates how the 'void' it is classified.

79kw
ABS

The max limit is 110kW. So you're ok...it is classed as an aux m/c space.
