The boat's name and its origin

The name of the boat, Delos, comes from a mythical island off the coast of Greece. According to Greek mythology, the island of Delos was raised from the underwater kingdom of Poseidon, the god of the sea, in order to provide a floating oasis for the twin offspring of Zeus, the god of the sky, and a human. Zeus' wife had banned the half-god-half-human twins from being born on any land.

The boat's owner, Brian Trautman, purchased the 53-foot-long Amel Super Maramu in 2008. The boat was built in La Rochelle, France, in 2000. It is one of the finest-built cruising sailboats in the world, able to accommodate six people comfortably. Trautman, an electrical engineer, has made various improvements to the boat, such as installing lithium-iron-phosphate batteries and an induction cooktop.

Its specifications

Delos is a 53-foot (16-metre) long Amel Super Maramu, a sailing ketch with two masts. It was built in La Rochelle, France, in 2000, and purchased by Brian Trautman in 2008. The boat can comfortably sleep six people.

Delos has made several ocean crossings, sometimes through heavy weather conditions, including severe lightning storms, and once tackling a 50-knot gale en route to Madagascar.

Trautman, a former electrical engineer, made several improvements to the boat, including installing lithium-iron-phosphate batteries with a battery management system to power the electronics. The crew has also taken steps to make the boat more environmentally friendly, such as removing the propane cooker and replacing it with a two-burner induction cooktop and a simple electric oven.

The boat has a hybrid-electric propulsion system, with one hull containing a Nanni N4.80 diesel engine and a 25kW electric motor, and the other hull being purely electric with a 25kW electric motor. This configuration allows the boat to run under diesel power, diesel-electric hybrid power, or pure electric power.

Delos also features an outside galley with a refrigerator, sink, grill/stove, and a fish fillet and prep station, as well as an extended roof to provide protection from the elements. The boat is fabricated from 5083 aluminium alloy and is fully insulated, making it suitable for both tropical and higher-latitude climates.

The boat has watertight bulkheads located in the forward crash compartments, forepeaks, amidships, and engine rooms, providing additional safety. It also has a forward sailing cockpit, which centralises the sheets, halyards, and winches for efficient line handling and makes short-handed sailing easier.

Delos has a massive solar array, with approximately 3.5 kW of solar power, providing ample energy for power-hungry systems. The boat also features an integrated rainwater collection system and optimised systems for life at sea, such as a unique aft dinghy platform that serves as a mount for the dinghy and a large space for relaxing or diving preparations when anchored.

The propulsion system includes a mechanical clutch that allows the diesel engine to be disengaged from the propeller shaft and run as a generator when anchored. The boat also has shaft-driven propellers and a rudder skeg, protecting the rudder and propeller from debris strikes and groundings.

The crew has also experimented with eco-friendly alternatives to traditional antifouling, combining a sonic antifoul system and slippery hull paint to avoid using toxic chemicals.

Its owner

The owner of the sailing vessel Delos is Brian Trautman, who sails with his wife Karin Syrén and their daughter Sierra. Trautman and his wife have been sailing around the world for over 15 years, dedicating their time to capturing and sharing the beauty of the world.

Trautman grew up in Flagstaff, Arizona, and worked as a diesel mechanic during his high school years. He later earned a degree in electrical engineering from the University of Washington and worked at Microsoft before starting his own software company. However, he soon grew tired of the 60-hour workweeks and began dreaming of crossing oceans in a boat. Inspired by the book "Three Years in a 12-Foot Boat" by Stephen G. Ladd, Trautman spent several years researching and saving money for his first voyage, which began in 2009 in Seattle, Washington.

Since then, Trautman and his crew have sailed Delos over 70,000 miles and visited 46 countries, documenting their travels and adventures on their popular YouTube channel, "Sailing SV Delos". The channel has seen rapid growth over the years, with over 846,000 subscribers as of January 2024 and has allowed the crew to support their income through YouTube with crowdfunding and Patreon campaigns.

In addition to his sailing adventures, Trautman has also made various improvements to Delos, utilizing his knowledge as a former electrical engineer. He has installed lithium-iron-phosphate batteries with a battery management system to power the electronics on the vessel and has taken steps to make Delos environmentally friendly.

The Delos crew has also engaged in numerous philanthropic endeavors, such as contributing to restoration efforts on the island of Dominica, which was ravaged by Hurricane Maria in 2017, and donating US$50,000 to various charities, including the Surfrider Foundation, which seeks to protect the world's oceans.

Its sustainability

The SV Delos is a 53-foot sailing vessel purchased by Brian Trautman in 2008. It is one of the finest cruising sailboats in the world, sleeping six people comfortably. The crew of the SV Delos have made numerous improvements to the boat to make it more sustainable and environmentally friendly.

One of the most significant changes was the installation of lithium-iron-phosphate batteries with a battery management system. This system powers the electronics on the vessel, including an induction cooktop. The lithium-phosphate batteries provide greater power over traditional lead-acid types, and a mobile app allows for easy battery monitoring. The crew also removed the propane cooker, which improved life on board and reduced wasted heat.

Another important step towards sustainability was the crew's decision to reduce the amount of chemicals used on the boat and going into the water. They achieved this by combining a sonic antifoul system and slippery hull paint. The sonic antifoul system, manufactured by NRG Marine, works by transmitting electronic waves through the boat that agitate marine growth, discouraging it from clinging to the hull. The hull paint, Sea-Speed elastomeric paint, provides an ultra-slippery surface that naturally sheds growth.

The SV Delos also features a hybrid-electric propulsion system, with one hull containing a diesel engine and the other a pure electric motor. This system allows for greater fuel efficiency and reduced emissions. The boat also has a gigantic solar array, providing power for even the most power-hungry systems.

In addition to these specific improvements, the crew of the SV Delos have also engaged in various philanthropic endeavours, such as contributing to restoration efforts on the island of Dominica and donating to charities that protect the world's oceans. They have also made efforts to reduce trash on board, such as removing packaging before bringing items onto the boat and using reusable containers.
