If you recall it has an acrylic cylinder CT and a K350 hatch. My problem is, the sub lacks volume to support the heavy hatch\land assembly. I do plan to increase the volume by installing a larger diameter leg tube. This volume increase is still not enough to give me enough buoyancy for stability during transition from surface to being submerged. Options are to loose the cylinder and go with dome. Make a lightweight hatch with GRP, or come up with a creative MBT that maintains buoyancy longer during submerging. </DIV><DIV dir="ltr">Hank</DIV></DIV><SPAN style="font-size: 10pt;">_______________________________________________
