Our Story

Born to cross oceans

Arona is a US-flagged Hallberg-Rassy 40 — one of 162 ever built — designed by the legendary Germán Frers and crafted at Hallberg-Rassy's Ellös yard in Sweden. She was purchased in Grenada in 2019 with a singular dream: to sail around the world.

Equipped for true offshore passages with windvane self-steering, a full suit of six sails, insulated hull for high-latitude cruising, and modern electronics alongside traditional navigation, Arona blends old-world seamanship with contemporary reliability.

Toward a Circumnavigation

Paul splits his time between the US and Japan, and started sailing while living in Japan. Ever since he learned, a circumnavigation was always on his mind. He progressed from a Yamaha 30C to an Elan 34 in Japan, then continued sailing in the Pacific Northwest after moving to Seattle. But for the dream of sailing around the world, he needed something bigger.

In 2019, he found a Hallberg-Rassy 40 for sale in Grenada. "Grenada is the best departure and return point for a circumnavigation. The trade winds blow year-round, it's well-suited for cruising, and from there you can ease into the bluewater life." He purchased Arona and began preparing her for the voyage ahead.

Riding the Trade Winds

The Caribbean cruise was born from a Facebook post. Paul recruited crew — Kawabata, who flew from Japan, and Linda Saza — and the three set off from Grenada on March 3, 2024. Some days they covered as little as 5 miles; others as many as 50. The pattern was simple: anchor in a bay, row the dinghy ashore, explore, eat at local restaurants, meet other cruisers, and move on.

They sailed the western side of the island chain, where the Caribbean's prevailing easterly winds are gentler. "Waves and wind come from the east, so the west side is calmer. But you still get plenty of breeze." Sparkling blue seas, clear skies, and the steady push of the trades carried them north from island to island.

St. Lucia & the Pitons

St. Lucia was one of the most dramatic stops on the entire route. The twin volcanic peaks of the Pitons — Gros Piton and Petit Piton — rise straight out of the Caribbean like green cathedral spires. Paul hiked both, taking in views that stretched across the entire island chain from their summits.

The Route: Grenada to the USVI

From Grenada, they island-hopped north through the Grenadines — Bequia, Mayreau, Union Island — then up through St. Vincent, St. Lucia, Martinique, Dominica, Guadeloupe, Antigua, St. Kitts, and on to St. Martin. The final leg took them through the British Virgin Islands and into the US Virgin Islands at St. Thomas. Seventeen islands, each with its own character, culture, and flavor.

Island Life & Local Flavor

Each island brought its own culture. The Caribbean's colonial history means languages shift from island to island — Spanish, English, French — and the food culture changes with them. Rum was the constant. Kawabata recalls buying big bottles of Coca-Cola and rum and mixing them every night aboard. "The rum is different on every island. They mix it with Coke on board."

Favorite stops included the floating bars of Bequia, where anchored sailors gather at sunset over cold bottles of Piton beer. At each anchorage, locals would paddle out to sell fresh fruit or ferry water to the boat. In the BVI, they met a group of Americans chartering a catamaran and explored The Baths together over lunch.

Exploring Ashore

The cruising life wasn't just sailing. Dark View Falls on St. Vincent — a twin waterfall reached by hiking through bamboo groves and tropical rainforest — was a highlight. In Martinique, they explored galleries filled with Caribbean art. And everywhere they went, the hiking was spectacular — ridgelines above turquoise bays, volcanic peaks, and trails that ended at hidden beaches.

Safety & the Road Ahead

Paul notes the actual cruising wasn't particularly difficult. The main preparations included adding a portable air conditioner for heat, replacing the life raft, and carrying an EPIRB, PLB, and Garmin inReach satellite communicator. He equipped Arona with Starlink for satellite internet — essential for his work as a financial content creator even from remote anchorages.

"The Caribbean is hard to beat. Dry season from November to May means stable weather. The bar for Caribbean cruising isn't as high as you might think." The dream of circumnavigation remains alive. Paul plans to cross the Pacific at minimum, and hopes to return to the Caribbean once more. "The dream of long-distance sailing is far from over."

Sailing Japan:
Secrets of Japanese Waters

The complete cruising guide to Japan — from the Ryukyu Islands to Hokkaido. Second Edition, March 17, 2026.

About This Guide

Japan is one of the world's great undiscovered cruising destinations — an archipelago of nearly 7,000 islands stretching 3,000 kilometres from subtropical Okinawa to the wilderness of Hokkaido. Yet remarkably few foreign yachts venture into Japanese waters, and until now there has been no comprehensive English-language guide for those who do.

Sailing Japan: Secrets of Japanese Waters fills that gap. Drawing on years of personal experience sailing in Japan and fluency in Japanese, this guide covers everything a cruising sailor needs to navigate the country's waters with confidence: clearance formalities and the Naikosen permit system, region-by-region harbour and anchorage information, navigation in the powerful tidal straits of the Seto Inland Sea, typhoon strategy, provisioning, cultural etiquette, and the unique Umi-no-Eki sea station network that most foreign sailors have never heard of.

What's Inside

The guide is organized into eight regional chapters covering Okinawa and the Ryukyu Islands, Kyushu, Shikoku, South Honshu, North Honshu, and Hokkaido — plus six practical appendices including a Japanese language guide for sailors, emergency contacts, a marina directory, recommended typhoon anchorages, cruising budget breakdowns, and a complete Umi-no-Eki directory.

Each regional chapter includes port-by-port coverage with moorage options, shore-side facilities, local highlights, passage planning notes, and food and cultural recommendations. Whether you're planning a two-week cruise of the Seto Inland Sea or a full circumnavigation of the archipelago, this guide gives you the practical information to make it happen.

8 Regional Chapters
Okinawa · Kyushu · Shikoku · South Honshu · North Honshu · Hokkaido — with passage planning, food, and culture for each region.
6 Practical Appendices
Japanese for sailors · Emergency contacts · Budget planning · Typhoon anchorages · Marina directory · Umi-no-Eki directory.

I welcome feedback and corrections — they'll be incorporated into future editions. If you've sailed in Japan, I'd also love to include your photos in upcoming versions. Please reach out through the contact page.
