Dimension Leap with A Held Rope

My Bard is holding one end of a 100′ rope in his hand. The other end of the rope is in a row-boat, either tied to the boat or held by another character in the boat.

The Bard casts Dimension Leap to teleport 90′ away.

What happens to the rope? We are trying to create a tether to attach a row boat to a ship, to be able to pull the row boat to the ship.
