Help the Sailboat Find the Island — Level 3

Very nearly the longest route on the site at 89 squares, and yet one of the more forgiving level 3 sheets, with 15 dead ends. The length is the difficulty here rather than the decisions, which makes it a fairer first 12 by 12 than its size suggests.

Sailboats cannot sail straight into the wind, so sailors zigzag back and forth, which is called tacking, to make progress. That makes a winding route a fair picture of a real voyage. The length here is the challenge rather than the choices, so it is a kind first 12 by 12 for a child who can stay focused for a while.

There is exactly one way through: no loops, and no square cut off from the rest.
