Shortly after Thomas and I decided to register team Sea Runners for the Race to Alaska (R2AK), we decided we should honor our boat-building experience — as well as James Wharram himself — by using the Wharram Hitia 17 design as the foundation of our race boat. Since Thomas is an architect and we both have built Wharrams (he a Tiki 26; me a Tiki 21), we hardly looked at the plans after laying out the hull sides and bulkheads. In fact, we’ve made a lot of modifications to keep the boat light and otherwise adapted to being powered by humans and the wind, rather than a motor. (The key rule of the R2AK = no motors!)
This post documents our 1-month build of the hulls — from plans to floating… First we present a fun build video that my son, Liam, put together during a “Tiki Tuesday” in a matter of mere minutes.
Below you’ll find a gallery of selected stills followed by the day-by-day build log. Enjoy!
This was a fun, fast build for us that made us feel confident that deciding to build a Wharram design with which we were familiar was a good strategy. We didn’t clock our hours exactly, but estimate it took us about at most 250 hours (42 days x 6 hours) the build time for the Hitia 17 advertised on the Wharram web site. (This confirms our suspicion that the build times and boat weights listed on the Wharram site are pretty ideal — maybe pie-in-the-sky. For non-expert builders, we advise multiplication by 1.5 for a more accurate estimates…)
