army sailor here. got 20 years in the business of a controlled collision with ground. in beaching operations a kedgeing anchor is used, mounted on the stern. equipt with wire rope. soul purpose is to haul ship off the beach. bow anchors are not used for normal beaching. only time bow anchors become involved for beaching is when you do a 3 point anchor. in which case all anchors are used. starboard bow, port bow,& stern.
When the ramp dropped I thought, there's no way a tank is going to roll out, but lo and behold, and pops an amphibious 😮. Congrats 👏. Its one thing to build a static model but a working one that floats 👏👏
Very cool. To improve the stability you either need to add some ballast (lead) low down at the keel, or reduce the water sloshing inside by adding longitudinal baffles. As others have mentioned, you have a GZ, BG and/or GM issue.
I generally use lead shot. I brought about 20 pounds a few years ago. I place the shot in condoms in areas I think ballast is needed. When I think I have the model stable and floating stable I mix the shot with epoxy and glue it in place. Not sure if you can still buy lead shot now as I have been told it’s no longer used in shotgun shells.
