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 finalise the work on the bow and the bow rollers. The bow itself consist of 5 Laser-cut AL 5083 parts, as well as the actual bow rollers that I 3D printed in ASA (as well had a pair made in Delrin). Some clevis pins and bushes and job done.
Cost Tracking
Breakdown (when applicable):
Parts/Material – Any raw material that I needed, or any ready made parts.
External Labour – External help with machining, milling or welding.

Lessons Learned
Lessons I learnt during this stage:
- There are more than one way to do bow roller wheels. 3D Printing in ASA worked great so far:)
