The best I've had was running up Tory Channel one afternoon, returning from 
a visit to the abandoned whaling station at the entrance. We noted one of 
the ferries approaching from behind us and sprinted to clear the point we 
were rounding and to give us some sea room to surf in. As it is a narrow 
channel we were moderately close, hard to tell how close to a 200(?) foot 
vessel (car/train ferry). The double took off nicely and Andy in an Arluk 3 
did even better.

The next day (still in Tory Channel) our group were discussing whether it 
would be possible to run down the middle of the fast ferry, a catamaran (we 
were joking weren't we?) when it appeared round the point in the distance. 
As we were to pass down the starboard side, the appearance, as it turned, 
of the port side, had us changing course a bit to port (OK we should have 
been on the other side of the channel to be "correct"). As the ferry 
approached she swung for the next bend in the channel  and passed us 
probably a good 100 metres or more away. The wake which has been a great 
concern to residents due to the damage it has been causing for the last few 
years, rolled towards us as a long lazy swell, totally unsuitable for 
surfing on.

It should be noted that at all times we were well clear of commercial 
traffic. Also just recently there has a been a bylaw passed which restricts 
fast ferries to a maximum of 18 knots in the Marlborough Sounds. Once clear 
and in Cook Strait speed is unlimited. The wake from the catamaran ferries 
does more damage than a normal single hulled ferries, possibly because 
there's a low/deeper "pressure" wave which, once it hits the shore causes 
havoc.
