Thanks to Mike M. I now have cannons for the EQ. Going back to work next week. Finally after 4 months of no income. Will be needing a list to order the rest of the system. Also need to decide what batteries I'm using. The 4 2300mah packs I have wired in parallel for 2 4600 packs. One each for propulsion and pump, or buy something else entirely.
I'm the new owner of this vessel and I was surprised at how much ballast it was going to need to float at the scale waterline : 6 lbs! After reading some of the discussions here, I decided that I wanted to concentrate the weight in the center of the ship and as low as possible. I removed the fiberglass "floor" in the bottom of the hull and carved out the tenacious pink foam that was in between the ribs in the midships section. A pound of #9 lead bird shot went into each cavity and then I used Loctite PL S20 Masonry Sealant to cover it up. I think it will be very stable on the pond. Hopefully it will be dry enough to float test it again tomorrow.
