Who sails what in the South Pacific?
To get a better idea of boats used to cruise SoPac, use a few of the Australian brokerage web sites - the country is big enough and technically advanced enough that you''ll find useful sites and some listings will include info on the boats'' history. All of this will give you a feel for what''s in use today. Try e.g. http://www.yachtnet.com.au/
You''ll find conceptually two categories of boats: 1. Those sold in N America, a wide variety in itself, then sailed S (the easier direction than returning home) and subsequently put on the market. 2. ''Local'' boats, mostly designed & built in NZ and Oz, a few in SE Asia, that are often less contemporary in design, some a bit klunkier in appearance and absent the current assembly-line manufacturing techniques, and most are probably inherently stronger given the waters in which they occasionally are sailed.
Or at least those were my impressions...
