Specifications

  

Well, things are moving right along.  Fabrication has now started this month (April) on A4702, so I need to catch you up on a few things.  So having made the decision to go with the Archipelago 47, we worked for several weeks on the spec for the boat.  It’s 21 pages long . The table of contents is condensed here, and  I’ll just bullet point a few items and attach the doc should you want to look at the whole thing.  Click here to see the PDF. An additional document called the VEL (vessel equipment list) is where things like all the navigation equipment is detailed. I’ll detail some of that in later blogs.  As a reminder, if you are viewing this on your mobile, you can select to see the web version (without leaving your mobile) to see the other blog options.  As always, feel free to leave comments or send them via WhatsApp +165038879800.

Introduction

The Archipelago 47 is designed as a lightweight, offshore leisure vessel balancing practicality and simplicity with sea-keeping and comfort. It is designed from the outset to be a diesel-electric [solar] hybrid vessel, featuring short-distance silent running from electric propulsion, and high speeds from diesel.
