The Scrumble Project

Building “Binary”, a Bob Oram 44′C cruising catamaran, in the Top End of Australia

Anchor system basics

This afternoon I gathered a couple of pieces of Duflex, that I had previously cut, and checked their fit into the small space between the two water tank compartments.

These pieces or bulkheads, will form the support structure for the anchor chain rollers and the sides of a wash down channel.

I then marked and cut out a ply template of the main anchor we will use on Binary, a Rocna 33, that weighs 33Kg or 72.7525465 pounds. The full size side elevation templates are available at Rocna Anchor

This made it easy to mark out the roller location while not having to get the whole 33kg, up close and personal, with myself and Binary.
