What this video covers

Dan and Kika install two custom water tanks in the v-berth of their 12-meter sailboat, prioritizing a modular design that allows for easy removal and maintenance.0:04 They construct a removable forward bulkhead using epoxy and glass, securing the tanks against movement while ensuring they remain accessible.1:05 To prevent structural stress, they line the support surfaces with cork and position the tanks over a reinforced hull rib.16:30 The system holds approximately 250 liters of water, split between two tanks to provide redundancy for long-distance passages.13:02 Dan uses 15mm PEX tubing and reusable SeaTech (now Aqualock) push-fit fittings to plumb the system, routing the lines to a service locker behind the head.23:01 The design allows the tanks to slide forward for removal without requiring a full disassembly of the plumbing.22:36 Dan notes that the pump and accumulator system requires careful orientation to avoid potential leaks near the motor.27:07 The project aims to reduce bow weight by replacing heavy stored materials with the water tanks while creating a dry, functional living space.15:25
