With the recent release of the final report of Nigel Calder's HyMAR project, marine internal combustion / electric hybrid powertrains are making waves once again- and not necessarily in a good way, as Calder's team found that the benefits of the expensive hybrids were limited to a relatively narrow, low-speed operating regime. We've known for quite a while that the major advantages of gas/electric and diesel/electric hybrid cars- namely, instant start/stop and regenerative braking- don't apply to boats. We've also known for quite a while that hybrid systems only make economic sense aboard ship if the house loads are comparable to, or larger than, the power required for main propulsion.

Tech addicts need not fear, though: There are many other fuel-saving and pollution-reducing technologies waiting in the wings, and hybrids aren't quite out of the running yet.

Good drawings take time to make. Time costs money. Therefore, good drawings are not cheap.

Some boat builders seem to think that this logic leads to a fourth point: "Therefore, we will not include drawings."

Er, guys? Not cool. Seriously, not cool. Just see what happens the very first time the owner has to have something fixed, and the technician spends most of a day rooting around in the bilges trying to figure out where the hell all the wires are going.

One thing I never really got around to learning in high school or in university was how to do a decent job with an arc welder. It's about time to change that- Sunset Chaser's trailer needs work, our weird new Starwind 860 will need a custom trailer, and there's always plenty of stuff that needs fixing.

It's one thing to read about how to do it- friendly old Google offers up 1.58 million pages on the subject. And, having been through engineering school, I have a pretty good idea how a weld works, what a good one should look like, and how the stresses are transferred across it.

Friends who know, though, always respond with "Well, you can read all you want, but the only real way to learn it is to lay down dozens of really bad welds until you start to get the hang of it."

So, for anyone else who's thinking of learning how to weld and is a bit intimidated by the idea, here's my "Day 1" report- complete with terrifying photos of beginner screw-ups.
