Yes I know the sounds well, including the inlet and location. But I am looking at this proposition as follows, unless I have it wrong.Samson, have you ever been to the Marlborough Sounds?

Disappearing a couple of bodies there would be quite easy. If they were murdered during the early hours of the morning on New Year's Day, the killer had plenty of time to do it under cover of darkness. Furneaux Lodge is only only about 7 km from the entrance to Endeavour Inlet and access to the rest of the Sounds, and only a further 15 km from the Cook Strait. Someone with extensive knowledge of boating in the Sounds to navigate it easily at night without lights. A small boat, a couple of hours, a couple of chains and an anchor is all you would need.
1. Guy Wallace dropped the three at the ketch, one of whom was the owner.
2. They separated from the owner and ended on a fizz boat rafted to the ketch with their killer, and an engine was started with no one on the ketch noticing (the police would have found a witness to this surely), and were dumped.
3.There happened to be enough anchor weight on the fizz boat to weigh down two bodies, and here is a post that discusses this issue.

I realise strong currents are not relevant here, but you see the point. Having said that, Watson would also need the weight, but he had more time.
