Video summary
Press to jump
- 1:03A thunderstorm soaks the taped roof seams, forcing the crew to redo its preparation.
- 5:10Brian and Simon solder the panel connections, using ice packs to limit heat transfer.
- 8:26Internal wiring runs through welded aluminum tubes, keeping exposed cables off the deck.
- 11:07Liquid polyurethane resin seals the junction boxes over the solder joints.
- 14:41Karin gets her first look at the finished, low-profile solar roof.
- 17:08The first live power test begins as Brian switches on the circuit breakers.
Sailing SV Delos has reached the satisfying part of a wiring job: the boat is actually charging. Brian watches the onboard display register solar power, then says, "That's pretty cool. That's exciting. I mean the boat is charging off solar right now."
Getting there takes rather more than flipping a breaker. In "FIRST SOLAR TEST….Too Good To Be True??? (Pt. 2) Aluminum Catamaran Build 93", a thunderstorm blows rain into the shed and ruins the carefully taped roof seams. Off comes the tape, followed by drying, re-taping and the patient business of sealing every panel border.
Brian, Karin, Simon and Nikki turn that setback into a detailed look at how the roof comes together. Ice packs protect the panels from soldering heat; wiring disappears through welded aluminum tubes; resin seals the little junction boxes against water. When Karin sees the finished roof, its low profile is the striking detail, rather than a separate solar arch rising above the boat.
The test episode was the most watched of two new uploads, reaching about 318,000 views. It is also comfortably the channel's busiest video right now, with the preceding full installation episode and the earlier cabin-and-appliances build update providing smaller streams of viewing. In the comments, practical questions take over: why smooth the sealant with a finger, how durable will the panels be, and could cooling them also heat water?
The subscriber audience held at a million over the week, while daily viewing is running below its usual level. Among nearby travel channels, Walk With Me Tim had a particularly busy week; Delos added more views than Wolters World, though fewer than Jet Lag: The Game. Here, the week's concrete progress is on the roof and on the electrical display.

This build has been an extreme master class in project management and execution! I'm really happy for y'all to see all these projects come to fruition.
@gdcasteelSee it on YouTubeWhy using a finger and not a silicone float?
@steve-1974See it on YouTubeAlways watching.
Thought I'd send a message to wish you well.
It's been 9 years now and I've never wanted to see a ship sail as much as I do this Catermeram.
Good luck and thanks for all the years of entertainment, knowledge and your hard work.

It’s incredible how much innovation is in this one boat. Some of these solutions didn’t even exist when you guys first started the build!
@VnazTSee it on YouTubeThose solar panels are an awesome looking product. Hopefully they show themselves to be reliable and durable for the next 5-10+ years. Thanks for sharing
@davidc6510See it on YouTubeinteresting that the panel connections use regular FDM 3d prints for the epoxy pots and caps. That'll be an intense test of the UV resistance of whatever material they chose, hopefully ASA
