After Block’s ship the Tyger burns down while moored at the souther tip of Manhattan he heads out in a new 44.5 foot, 16 ton vessel called the Onrust (restless) that his men and Lenape built. He is the first European to navigate Hellegat (Hell Gate at the East River) and enter the Long Island Sound. Along the north side of the sound (Connecticut) he explores the Verse River (Connecticut River) and the River of Red Hills (Housatonic River). He briefly visits the New Haven Harbor area (New Haven), later to become the site of the New Haven Colony. Leaving the sound he charts Block Island and Narraganset Bay.

On October 1, at Cape Cod, Block rendezvous with Christiaensen and the Fortuyn. Returning to Europe, they leave the Onrust behind.

In 1916, remnants of the Tyger are recovered while digging the New York City Subway at the eastern edge of the present World Trade Center complex.
