Just read about this manufacturing breakthrough that purports to cut in
half the cost of producing lithiun ion cells.
From what I understood, it allows the electrolyte layers to be thicker
and manufactured in a continuous roll and avoid drying times. I
especially like the $0.10/wh projection by the year 2020. At that cost,
lithium will be the best thing going by any metric for electricity
storage in boats.
My existing 5kwh pack cost just about $2500, including BMS and battery
packaging (straps, buss bars, etc). Others here have also said under
$0.50/wh is achievable. To bring the cell cost down to the $0.15-$0.20
at low-volume retail level would be just absolutely amazing. On a
per-usable-ah level, that is on par with wet-lead in price even
including a basic BMS, but still has all the volume and weight
advantages of lithium.

Thanks for posting this. That article is exciting. Since they are my neighbors I think I'll write and volunteer my boat as a test vehicle. Can't hurt to try.
I finally got someone to lift my old diesel(Volvo MD1) out of the engine compartment and I'm working on getting out the rusty steel framework on which it sat for 44 years. 7 out of 8 hardened steel bolts out, 1 to go. It is corrosion welded to the 1.5 by 1 steel bar. Once that is out I will clean thoroughly including the bilge, repair holes no longer needed and paint - white instead of the original harvest gold.
