Never been to Holland, but have known many here in AU over the years. To generalize, they come across as both very meticulous and very insistent. F'rinstance, some years ago when I was doing a fair bit of yacht racing I was detailed as a scratch crew to help a yacht club member get his 54 footer back from Broome to Perth as his crew/family had had enough and jumped ship.
So, four of us flew to Broome, provisioned up and got aboard in heaving seas. Things all pretty cruisy for the first day or so we were underway, taking 4 hour shifts alternating with the other guys. But the skipper was Dutch. And by the second day the Capt. Queeg characteristics started to emerge, with a relentless full-toss racing pace maintained while we bashed into 30 kt headwinds for day after endless day for the couple of thousand nm. So, for setting a totally un-necessarily cracking pace
(with all the significant discomforts that involves), while at no point being observed to stand down for more than an hour a day himself while also doing simultaneous navigation by gps, celestial and dead-reckoning methods with un-nerving accuracy. When there was no rush to get there.
Just a complete bastward, but the most competent, capable sailor I've ever sailed with.
Sure his "Dutch-ness" had much to do with this situation.
