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.”

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.

Another headache on Koopamans’ trip was caused by red tape, most notably in Cuba. “Watch out in Cuba,” he warns. “Eleven government officials came to inspect, fill in and sign the same papers.”

Beware the charts, Perkins warns. “The charts in Alaska aren’t terribly accurate. We ran aground with Andromeda and the nine metre tide left us totally out of the water on a bank of shale. We rigged kedge anchors far outboard leading to the mast top, to prevent tipping over (it worked) and all aboard went ashore for safety for eight hours before the tide started to return,” he recalls.

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.”
