Foreword
Welcome to my Kiribati 36 DIY build journey. A 36′ Aluminium ‘Bluewater’ sailboat with twin rudders and a retractable keel. After completing a global circumnavigation on two wheels (See: Blog | YouTube) I now set my sights on doing the same by water. My hope is that the build, cost tracking and lessons learned will aid aspiring boat builders in their own quest. Please know the following:
- I have no affiliation with the company selling the boat plans, in other words, my words are my own. I am however affiliated with Google AdWords in the hope that any revenue made will assist towards the completion of this project.
- In the event of me deviating from the original build plans, adding my own parts, or amending parts then this is highlighted in the articles with ‘** Note‘.
- An up-to-date parts/article Index (including total expenditure) can be found: HERE
- Feel free to ask question via this blog, YouTube comments, or email: kiribati36 @ modularhippo.com – My aim is to respond to all questions within 24 hours.

Build Progress
Time had come to start the work on the Keel Pivot Mechanics, or Keel Pivot Bearings as I also sometimes referred to them. The keel pivot ‘rests’ on these ‘cradles’ and allow it to pivot. This stage held allot of individual parts that was all very similar but with small differences so it was important that I figured out exactly what was what. This was easiest done with writing the part numbers on masking tape and mark all of them. Then put parts together before weld and take allot of photos. Once the arches had been lathed the positioning of them had to be kept in position so got stamped with ‘A’ and ‘B’ on respective halves.
Below is the individual parts, organised and later welded:
Cost Tracking
- Parts/Material – Any raw material that I needed, or any ready made parts.
- External Labour – External help with machining, milling or welding.
- Tools & Misc. – Cost related to project, but not part of physical boat itself.
