How Deep a Keel is too Deep?

This was the same quandary I went through when buying a boat.
I wanted performance, but sturdy. I wanted something that could go into most places reasonably well on a normal range of tide but I wanted a boat with decent cruising or racing speed. I like to do longer passages and the higher average speed potential makes a difference.
I looked at boats around 36-40 foot, always fin keels, and they varied from 1.6- 2.3 draught. In the end I chose a smaller boat with a relatively larger draught (1.85) compared to the length, to hopefully have good performance but also ability to gain access to places.
So far I've only touched the bottom a few times, deliberately. It's also reassuring to know that the cast iron keel and boat construction are sturdy enough to dry out against a wall. I don't worry if I touch bottom occasionally in shallow creeks.
I kept my boat on the east coast originally and access was a little limited to some of the places over there, but since being on the south coast, I'd happily have a boat with a slightly deeper keel, but I wouldn't go above a 2.2, as then it gets to be a real pain in the arse getting into nice places.
The swinging keels of the pogos/jpk etc have a nice solution to keep performance and a 3m keel but lift it up and have just 1.5m for tucking into shallower areas.
If I had the money, this would be my choice. A high performance swing keel.
 
In the Solent, 2 X 3ft suits me just fine. I can get into places before, and leave after, the big boys and if Newtown Creek is a bit full, I can sneak into a corner and dry out well away from the deep finned riffraff :)

I've also found it useful round the back of Brownsea Island, with a foot of water under my keel.

OTOH, A Snapdragon probably wouldn't be my first choice for a non-stop round the world cruise. I doubt I'd drown, but starvation might be an issue
 
If you want a bay which is close to Agana for perhaps a quick getaway on your arrival day then just 7M south of Agana is Drevnik Veli. There is a bay called Krknjas at the very SE corner...

We bought the boat through the Moorings ownership scheme so we owned it and named her from brand new and spent several free holidays on her every year until it was handed to us full time after 5 years. We spent so much time ....

Thanks for both sets of input. Food for thought.
 
I just love my Southerly swing keel, 0.9 to 2.5 m...we don't dry out very often but find it incredibky useful getting into and out of places in the CI and Brittany and take advantage of it almost every time we go somewhere

Despite that I have to admit we have clonked the keel a couple of times on marina sills(very gently)
and a number of occasions on sandbanks or river bottoms ...just press the button and away you go even on a falling tide
 
I have recently move from a boat with 2.2 m keel to one with 2.5 m I am sorry but the extra 300 mm is a pain in the rear. As the max depth for my boat yard on Aegina 2.35 m
Now who`s a stupid boy then.

No silly, just an oversight! This is exactly the reason I am posting this - what are you likely to miss?
 
You simply learn to live with what you have.
I find that there are just a few harbours that I can no longer go to, having moved from 1.5 to 2.1 m draught.
That is offset by much better performance upwind and speed and that is a trade-off I gladly make. It simply depends on your type of sailing and your chosen cruising grounds. There is not one right answer.
 
We have 2.5m but with a large tidal range it's not too much of a problem except we are unable to use a number of marinas.
 
Where do you find you are not going that you did?

Genoa,
No where yet, although I did get stuck in Ryde.
Tidal calcs showed we would have enough water to get out an hour after high but because the mud builds up around the wall where we had dried out, I touched after pulling away about 2feet. I chickened out and return as to the wall and I had to wait for the next tide (difference of 0.1) to escape. Funnily enough my old boat was there and motored past around an hour later on there way home
