:) I wrote a post and it got blocked - so lets try again ...
Trip planning and fuel management for that trip would have been part of the challenge. I'd guess there would have been some parts where they needed to be careful of fuel burn to make it from one refueling stop to the next e.g. around Fiordland.
Running at WOT burns sooo much more than even a handful of knots slower. A recent example for me was last Thursday we got an "URGENT CALLOUT" page. A client on a fishing charter had collapsed and they wanted Hibiscus Rescue 1 to respond. We were running at WOT and sitting on 44-45 knots from Gulf Harbour out to the container boat anchorage towards Rakino and then south to find the charter boat, transfer the guy onto HIB1 and then take him and a support person down the Marine Rescue Centre to meet Ambulance and Police - also running around 43-44 knots once our guests were settled in. (The guy who had collapsed was pretty good and had pretty much regained his senses when we picked him up but we still didn't want to waste any time.)
Fuel Burn stats:
- The two legs of the triangle at WOT / close to WOT consumed 130 litres
- Mechanics Bay back to Gulf Harbour burnt 51 litres at 37-38 knots (I was on the helm for this leg so recall the speed)
Total time from "home working and the pager goes off" to "back home on a call with my boss" was 2 hrs 15 minutes - but I didn't track the leg times or distances.
HIB1 has two 300hp Yamaha 4-strokes so a different fuel burn profile 2 a couple of 2-strokes.
