The wooden square with the handle is the interior access to the main ice box. It also has 5" of insulation on it and slopes downward into the box to minimize cold leakage. Also visible in this photo is the propane burner and the galley sink. Not visible here is the foot pump below the shelf below the icebox access.
The box handily holds 20' of 5/16" chain and 150' of 7/16" anchor line.
Here's a fairly close view of the window from the outside. You can also clearly see the dead eyes and chainplates with terminators and the shroud lashings. The sliding hatch for the companionway is also very clear.
A port side view of Abaco showing the window and also the bimini. The bimini was built for us by High Seas Fabrication of Stuart FL. They did a real great job for us. The bimini provides lots of shade, standing headroom and as an extra bonus good hand holds at crucial locations. We did however forget to put a window in to be able to see the mast head and mainsail leech. We will have to have this added.
