Risk and Reward
IMO, If you hit anything fast enough and hard enough then there will be damage. The Titanic comes to mind.
You are right, of course. But perhaps it is also good to view this with some perspective. Otherwise you may construct a "strength graph" with only two vessels: a heavy and ponderous Westsail 32 at one end and at the other end that former AC boat that split in the middle from rigging pressure. In reality the strength curve is somewhat like the potential curve for showing what is/is not a "Blue Water" boat. This is argued endlessly and to silly extremes on the internet, and often by people who have spent no time 'out there'. (IMHO)
Think os it as a rather long scale, with weak boats (Weak engineering, thin layups, poor design) on the one end and the stronger ones in
all those categories on the other. The money outlay goes up with the construction quality, as you might expect.
Further, very few of the internet opinionated "sailors" actually have offshore experience in a variety of vessels. We are beyond fortunate on this site in having several with massive offshore sailing time in self-sustained vessels. (For all of my shorter-route delivery experience, I am only a C+ or B- student in comparison, to put it in old school terms.)
On the upper part of the strength graph are the stronger boats like the Ericson's and at the low end are the 'sunny day nice weather' boats like most Hunters. The 'low center' part of such a graph is crowded with middling-quality production boats, and the part above the Ericson is rather sparse.
If you run into something hard enough at the right angle, nearly all boats will sink. What we have done by buying E-boats, by shrewd calculation or dumb luck, is bias the potential damage calculation and risk in our favor.
There are a host of cheaper 34 boats that I could have bought, but when moving along at 7 kts plus off the WA coast I love having the odds be much more For me than Against me.
In the Pacific NW, hitting a pinnacle rock is always a risk, and I personally know of two boats that have done do in the last few seasons. Bob's E-34-2 did so, and received only a ding in the lead keel, and no structural problems.
A Portland boat that I am familiar with did virtually the same thing -- a
violent halt at 6 kts -- and came very close to being an insurance total. Their inside hull structure that supports their keel was bacly fractured along with the structure up one side that supported the shroud load. Much interior re-construction
and new rigging; about 40 to 45K total.
Insurance paid, and the boat was out of the water for several months. The owners quietly admit that they bought this boat for it's large interior and general "value", and just accept it's weakness. They also are very lucky people. Yes, it's a voluminous (!) late model Hunter 37x model.
So, when hitting "stuff" it's good to have more vessel integrity keeping the odds more in your favor. Ultimately there are never going to be guarantees, our E-boats give us the additional edge that knowing you have an ace in your hand gives you in most card games....
