Seaview

[ADDINGTON]

Mark,
I had similar designs with the DeBoer80 (my tank eventually sat right down on the keel) and would tell you that every effort to lower the ballast tank that increases floodable volume below the surfaced trimline will be rewarded
and well worth it.
I am anxious to see your results with best success wishes.

Thatll be COOL!

I'll get that new 3" SD to you soon, Mark.

Im getting the itch again. Im wanting to lower the Subdriver down inside as low as possible. That way, Im hoping it will float higher in the water. Right now the subdriver is mounted 5/8" up off the bottom of the inside hull. If I could lower it down 1/2" I think that will raise the boat 1/2" in the water. I Hope.

Just found some long lost pictures of the Seaview in its early stages. Here she is in my makeshift paint booth using one of the bosses old sheets to keep paint off the garage floor.

I managed to get the rudders installed. Because of the shape of the original rudder, these new add on rudders dont run parallel to each other. Perhaps it will create a ventura effect and increase their effectiveness. We will see.

[greenman407]

As can be seen from the pictures, this boat is steered by the action of the water coming from the props over the rudders behind the propulsion tubes. As those rudders are configured now ,only part of the water stream can act on the rudders. If the rudders were hinged in their centers, then the rudders would be affected by the entire water stream. The center rudder is very small and pretty much hidden by the hull to the flow of the water. What I am doing is extending that rudder down into the flow of water beneath the hull where they will do more good.

Oh yes Rick, that part works real good. I do that manually or I can sit still and swing her bow around ,NO PROBLEM. This is to reduce the turning radius when using the rudders alone.

[Rick Teskey]

Have you tried seperate speed controls and linked them too the rudders for differential steering?
I know Kevin makes a throttle jockey for this application.

The time has come to help the turning radius of this boat. Im going to make two add on rudders sized 1&3/4" long and 7/8" wide. They will be CAed ,one on each side of the central rudder underneath. By installing two of them it will form a trough that should increase their effectivness. The only downside, other than not being part of the original design, is that they will hang down below the keel a little bit. So unless I want to plow some furrows, Ill need to keep it up off the bottom.

This one follows the other one as she was shown here misbehaving but operating nonetheless. These videos wont win any prize but lets be realistic, they wernt being made with that in mind.

This video was taken back in 2008. It was around the time that I was having a lot of trouble with the Seaview. It was eventually traced to incompatability between the onboard electronics and my Futaba PCM radio. After I purchased the Polk Tracker I have had no further problems.

Ok Thanks I got it.

BTW, that was just an example, plenty of other options on that site.

Subculture, can you provide the link again to the ESC and the motors because I cant find it. Thanks
