[PSUBS-MAILIST] SeaQuestor progress

 David, It is good to see the 80 tank, because it gives a size perspective.  In the pictures earlier the sub look much bigger.  Ya what's with the new nose?  Did your creative juices kick in?Hank

 Hi David,I was concerned that it wouldn't be hydrodynamic for towing with thelower shark jaw. Possibly you could have had added buoyancy there, But if it's to inspire kids well & good. Alan

Hi Alan, I revised to canards to inspire the kids. Hidden in the nose is the red camera mount rack. A section of the nose cone will be able to be removed. This prompted a change to the shape, so I thought for fun why not take on the biomimicry of a shark. Afterall the SeaQuestor is a crashed spacehip into the ocean depths and took on some elements of the creatues of the deep. It will make great story time with the kids. As for the tow hook, it will be placed in the mouth area. I waited to have it cut out of ss until the final shaping to be welded to the  forward hemi. It is placed about the line of cg, and should tow with the nose up to counter act the slope of the exoskeleton.David

Also David,
I can't see a provision for a towing hook.

> Hi guys, the progress continues on the SeaQuestor given the amount of time now available with the stay at home orders. Currently the foam work is taking shape on the exoskeleton. Lots of sanding shaping to get the lines to look and feel right. Once I'm done with one side I get duplicate the details on the opposite side. Today after sanding the front canard, I placed the periscope tube forward of the front pilot to start the final foam fill. Next I started on the aft tank area. The first 80cuft tank is set into its holder. I discovered that the lower area below the tanks will completely conceal all of the tanks, which I like. The the high pressure tanks will be connected to the three holes cut into the rear hemi. The aft rack also holds a pair of thrusters which will be vectored. The mockup shows the control  brackets yet to be mounted once I get the linear actuators. The vhf antenna bracket is also mocked up.  Everyday a little bit more is coming together.
