I have a full navigation setup on both my main fishing yaks. I have a LED red and green combo light on the front and a LED white pole light on the back (just like a lot of bass boats have with a base and removable pole light). I run these lights along with my depth finder off of a 12v 9Ah battery. Its the same battery that a lot of computer battery backup units, trail cams and child's power wheels use. The battery weighs about 5 lbs. On my Tarpon 120 yak I have 1/4" mono jacks on both sides that I plug my MOONlite Half MOON into when night fishing. I have not set the new Hobie Pro Angler up yet with blacklight jacks, but do have some now (just need to find the time to install them). I pretty much only night fish here local, either Patrick Henry Lake or Boone Lake. We go fishing a lot after work and I got tired of having to get off the water before it got dark, so I added the navigation setups. Then I started liking being out after dark, so I had to add a Half MOON! I love the Half MOON, its so small, yet so powerful! I think it would just depend on the yak as to weather you would have a flat area to mount the rub rail light system. I am thinking it might be hard to do on my Tarpon, but probably very doable on my Hobie Pro Angler. If I can get up towards Watson's I will check them out.
