That one is a very old list.
That one is a list made up by people doing commercial
That list is just a list and cannot contain all boats.
That list was written by someone, from their individual view point.
No point in discussing that list
all that much.
A sound, well maintained and prepared B331 will have as much of an adventure as any other similar sized boat on the same route
. Like anything, she will ask for good seamanship.
The last leg from the islands to NZ is where things get interesting. Sail it well and hope for the best.
BTW I think more boats run into dire trouble there sailing out of NZ rather than sailing to NZ.
Ask Mark what his boat is. Look at what Webb sailed to and from NZ.
