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.
Cost To Date: £23,657.45->£27,448.12 | $30,484.84->$35,511.12
