15 lessons in circumnavigation

Koopmans learned the hard way to pick crew with great care. “You learn to work with crew and their wits. Generally we had a great crew apart from one criminal chef who made transfers to her own account and disappeared.”

Cape Horn should be rounded in December, according to Perkins, but even then it can be calm or horrific.

“We had only a perfect 20-knot breeze on the beam, so we sailed around the island and then on across the Drake Passage to Antarctica. The following year at the same time a friend with a similar yacht encountered 120 knots of wind and was unable to round,” he remembers.

The homeward journey across the Indian Ocean took Zeepaard into pirate territory, something Koopmans was well prepared for.

“We made extensive modifications, including wrapping her up in chicken fence, barbed wire and electric fencing,” he recalls. “We also stuck a military number – ZP01 – on the bow, fitted shooting bunkers on deck and modified the engine room into a citadel from where we could operate all controls.”

For extra security, four Dutch Navy Seals joined the yacht for the journey.

Taking their children out of school was a big decision for the Ryans, but one that paid off, with their three daughters learning a huge amount.

“We took tutors, opting for a married couple on the recommendation of an agency, as we got more bang for our buck. Plus they were able to be a unit unto themselves, which meant they didn’t need to always be with us or the crew,” they say.

But the girls’ best lessons were thanks to the decision to promote the first mate to captain: “She was our first female captain – and the first-ever female skipper of a superyacht – and a fabulous role model for our three girls.”

Some of the sharpest memories for the owners of Twizzle are of Papua New Guinea, at once the most frightening port of call and the richest culturally.

“Papua New Guinea can be pretty scary and we were made to leave some of the islands we visited, despite having a knowledgeable guide on board,” they remember. “But we were forewarned about the dangers and it was worth it as we saw some extraordinary sights and met some of the most colourful people in the world.”
