$89 million divided by 12 = $7,416,666.67 per boat.
That divided by 85 feet per boat = $87,254.90 per foot.
Did I do that right?
Have you priced other modern vessels per foot? I get about £2.1 million per foot for a Type 45.
(£1.050 billion per vessel, divided by 500 feet in length.)
Is that cost effective? Seems to me that question is being asked in a vacuum.
