Many French boats use that type of keel that is probably the best solution to reduce draft (out of swing or lifting ones) with a minimum loss in performance. It is for that they are used and to provide a beaching solution:

Left Brain, I'm really surprised to hear you, a self professed engineer, to make such a sweeping and unsupported statement.
IMO, a well designed and built fin can be just as durable as any other sort of keel, be it bolt on or encapsulated. And a poorly designed traditional long keel can have difficulties too.
After all, there are literally tens of thousands of now elderly fin keel boats sailing about the world... with their keels still intact. They seem to me to outweigh the Cheeky Rafiki's of the world by a pretty large margin.

Re: What type of keel do you prefer?
More importantly, do you prefer blondes, brunettes or red heads?
I prefer any keel that is currently attached to a boat. I am not too fond of the ones lying around the yard, and even less keen for the ones on the bottom of the ocean no longer attached to the boat.

Re: What type of keel do you prefer?
My keel just happened to come with the boat  and i paid no attention to the type. Im pleased its a keel (modified full i think) that protects the rudder and prop.
So, as for keels i dont like, im not keen on bolt on's as ive seen too many up on the slip with cracks from movement. And im not keen on ones that leave the rudder or rudder stock stuck out on its own for just about anything and everything to snag on it.
As im intending to be a cruiser, im thinking full keels hold course better?

Re: What type of keel do you prefer?
Keel selection no doubt is influenced by use of the boat. My perspective centres around cruising in bommie strewn and sometimes remote areas. After seeing the results of a 40+ foot bolt on a fin keeler that hit a reef at speed (and then gone over the subsequent repair with a fine tooth comb), I became convinced never to consider a boat with a bolt on keel ever(*). Having owned a (older) boat in the past with a spade rudder and having had been worried every time we were out of sight of shore that it was either going to break away or otherwise fall out, I've never been able to consider these again either. But that's more me and my thinking then any dump on the design I guess. I ultimately prefer an encapsulated modified long fin keel with cutaway forefoot (for little other reason than to help it to ride up over things it runs aground on) and skeg rudder. I feel this gives the best compromise of tracking, performance and draught for a cruising boat.
(*) I've read bolt on cast lead keels can absorb shock loading in a hard grounding which results in no overstress at the attachment point and the dented lead is easily repaired. If this is the case, these could be a bolt on exception.

What DonCL says, because no keel is finer than that of a Columbia 29!

For what intended use?
For example, my H33 has a deep narrow fin. Great for racing and day sailing, but would not want that for cruising.

Re: What type of keel do you prefer?
I am OK with mine... shallower draft would be better for obvious reasons. I like that the keel has a huge thick flange on it set into a pocket and the bolts are off the center line for more strength. Fully skegged rudder won't be falling off either. Note the fully encased prop shaft as well... another good idea.
This hull was offered with deep fin, shoal and wing.

One that's attached to the boat. (Just a little Beneteau joke there...)
