Abysmal progress, I know, but progress nonetheless. Rear dive planes were drafted and printed in high strength resin. I actually really like the configuration of the stern. The rudder is directly behind the prop, which will, in theory, offer some great yaw response. The rear planes are really conveniently located where they don't interfere with the prop shaft. They're large and situated well in good proximity to the propeller. I am anticipating good pitch response from this boat as well.
Next up will be engineering the rudder actuation. There is room for a tiny horn, however I will likely go with something like a pull/pull steel cable on a wheel in order to keep it close and tidy back there.
Once the stern is finalized (and we're close on that), then it's onto the crazy forward dive planes. I've spent quite a few hours pondering how to engineer the push/push extending front dive planes. The biggest challenge is the narrow bow. When retracted, the planes actually almost touch the inside of the opposite side of the hull. For those unfamiliar, the bow planes are engineered such that there is one on the starboard side to surface, and another on the port side to submerge. Proportional control of surfacing/submerging is handled by pushing out the respective dive plane to different degrees. The advantage to this is that when a level bubble is achieved and desired, there is no drag from forward dive planes. The disadvantage is the crazy linkage needed to make it all happen.
More soon, though progress will likely be further stalled by preparations for SUBFEST, which is in 2 weeks.
