Tohatsu 2,5 HK over Atlanteren
Smallest motor to ever cross the Atlantic
- a 2,5 hp Tohatsu brings Seiko Nakajima safely to New York.
On September 10, 1994 powered solely by his 2.5hpTohatsu, he began his trip in Basel, Switzerland, and headed out to the Mediterranean Sea via French rivers and canals. On October 30, he reached Gibraltar; on November 16, the Canary Islands.
During the 27 day open-ocean portion of his journey across the Atlantic, Seiko survived in an extraordinary manner. He ate only crushed nuts and seeds and drank one liter of water per day. The enclosed portion of his boat, in which he spent most of his journey, is barely high enough for Seiko to kneel in and just long enough for him to lie down.
He slept only one hour
at a time so that he could gauge his position and progress frequently. He did not bring any reading materials with him so that he could keep his mind focused on the trip.
The boat, which Seiko built, is 21’ 4” long with a 5 ft beam and a 2 ft foot draft. It is made out of mahogany wood with epoxy and fiberglass and is completely enclosed.
Building model boats has been a longtime hobby of Seiko’s. His boat, the “Seiko da Gindelwald,” is a full-size replica of a model that Seiko made. The bright yellow boat is the first full-size boat that Seiko has ever built.
