Really!!! At 5-10 times the price of FLAs per amphour rating or 3-5 times the price of FLAs per usable amphour, they would have to last at least 15 years to match FLAs on an amphour year metric.

I have never owned a boat for 15 years, so I am unlikely to ever find out if Li batteries can last that long .
