The catamaran was clean, modern and provided a mixture of mostly individual seating with a few tabled booths (snacks can be purchased with free complimentary tea or coffee available from small bar) as well as outdoor seating- first on best seated! Baggage gets stowed in large containers that are then covered before getting (via forklift) winched on to the rear of the boat where they are tied; small packs and bags allowed with you (1 per person). Timely and efficient on both trips (approx 1 hour each way), the crew of three including the pilot were happy to answer any questions we had about the ferry itself, islands, weather etc. Both terminals have seated lounge area with toilets and tourism pamphlets/DoC info available to peruse while you're waiting to board (check-in 30 minutes before departure) though a cafe serving snacks and hot drinks (we were hanging out for a coffee after a long early morning drive to get to ferry) might have been nice (note, there is a cafe within walking distance close to both terminals, or come prepared and buy before you drive to the wharf at Invercargill). School holiday periods usually have a special deal where a child travels free with a paying adult, which was great for our group. At $135/adult return trip we thought this was pretty good value and it was a unique way of seeing the mainland as well as other islands including Stewart Island from a different vantage point... and it sure beats swimming!! Easy to get on and off (we saw another ferry winch a wheelchair on board). One trip a bit rodeo (think bronco billy in a smooth but predictably rolling way) and the other was almost eerily smooth like oil! Felt safe though!
