A 6 foot draft on a 50 foot boat that IS a shallow draft design. My issue with fin keels is the inherent structural incongruities with an increased (and increasing) possibility of catastrophic failure. A cursory search on Google of "boat looses keel" is disturbing to say the least. .....
Not to mention big sail yachts from whom a 3.00m draft is shoal draft. You a smaller boat or a boat that can raise the keel you can go to more places and be more nearer from the beach, or on the beach but that's all.

Regarding losing the keel if you pay attention those boats are very high profile racers that have been built to be as light as possible and that are to be used with regular inspection checks to all stressful parts of the hull. There are no cruisers losing keels, not even big mass production cruisers at least to in any meaningful number.

There are cases where boats are thrown to the coast by storms or bad navigation and even so the fin keels survived. You have the recent case of that Sydney another one with a Mini class racer that was put again in the water and sustained not only the efforts on the way to the beach but also the efforts when the boat was pulled again (by boats) to the sea again and you have for instance these cases:
