Puzzle Boat

You have been captured by art thiefs sailing the seas looking for art. You were handcuffed and put in a cell, but when the crew spotted a pyramid in the distance, you knew it was you chance to escape. You slipped off the handcuffs (just like in the movies...) and now it's up to you. You have to get off the boat before they get back.

When you escape the boat find out what happened to the crew, they aren't there... but you can assume.

Rules:
Must be done on survival
At least easy
no destroying or placing blocks (except obsidian)
Good Luck

Additional Notes

please comment with additional suggestions

I have not finished the pyramid and need more challenges
