The reason the marina probably requires you to have a
holding tank is to help reduce accidental head discharges into the water, which they can be fined for. If someone does use the head on your boat, and you have not
holding tank...guess where it goes.
I would look to an Islander owner's group for information on fitting a
holding tank, as they'll have a fair amount of experience with it.
One that may be able to help you is:

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
