The cost on maintenance for the amount of times you use it. A lot of people get boats but then hardly use it, my boat really had to be used every weekend for it to be worthwhile and didn't have time, the conditions weren't always good for taking it out so hardly go used.

The nuclear subs from US/UK are a better choice even the ALP agreed with that. French subs are rubbish, now the conventional builds may have been taking so long and costing so much because of a modification but they knew they were making modifications and so were over budget and behind schedule even after taking all that into account

The French nuclear subs are shit. The diesel subs also were behind schedule and over budget.
