Now that I’m back from San Diego, I finally get to post about my boat.

This boat features a drive system known as the Voith Schneider propeller (VSP), which is those blades you see sticking out of the bottom of the ship. Wikipedia has a more detailed explanation of how the system works , but in short the system works by rotating the blades in a circle while changing their angle, in effect “scooping” water in a particular direction when the blades are not tangential to the circle they rotate in. The direction of thrust can be changed by moving a control rod that controls the center of tangency (?) of the blades (the blue dot in this diagram.)

Well today’s update is a lame ass drawing followed by a wall of text.

One more version/view Normandie. This is a slightly earlier version than last week’s. It is shorter by one “section”. The bumps on the top are lifeboats. That being said, in what can probably be labeled an impulsive purchase I picked up the (old, 2010) 11-inch MacBook Air about a week and a half ago.

It’s “Boats 2011 Part3″ this time because on Saturday the 13th, I drove Titanic off of a wall and into a debris field, losing my only propeller in the process.

Officially, I want to name it “Ita-Titanic” or something along those lines. This is obviously a play off of “itasha“, and the reasoning will become clear in a bit. Also considering the coincidentally appropriate “Itanic”. As of the last update, there was still a bit of work to be done, but at this point I think it’s more or less complete (for now).

I say “for now” because this is as much an art project for me as it is a hardware project… or at least that’s how it’s turned out. When J and I first considered doing boats round 2, I had really just wanted to bring Titanic up to par mechanically (fix the leaks, streamlined circuitry, real ESC, etc), but as I mentioned in the last update, once the mechanical business was sorted out, I got caught up in cosmetic improvements. Even then, I’d originally only wanted to make the single cutout as shown last time, but things just kept going.

Well, it’s been a while since the last update. Admittedly I haven’t really done any drawing since then, which is why this is a non-drawing update. Instead, J and I are doing RC boats again. A few years ago, we basically took scratch-built RC boats and sputtered around a pond(?) near J’s house for loads of shits and giggles. Hopefully there will be more giggles and less shits this time around. I think the tag is “hardware project” or something to that extent.

This is the Titanic. I call it the Titanic because the hull is actually from an approximately 1:350 scale model of said ship. When I was very young, I bought the kit at my (now long defunct) local hobby shop and putting it together at that age was obviously disastrous. Over the years, the rest of the ship has gradually been torn up and discarded, but just getting the hull has probably been well worth the $60 I paid for the entire kit.
