But that is true of many products. How many times do you hear (or even have direct experience) of cars being written off despite there being little visible damage?
It is nothing new in boats. It is their nature that you can get hidden defects because much of the structural strength is hidden by subsequent parts of the building process. This is true of all forms of construction and materials. So, it could be rot in timber, failure of fastenings through corrosion, hidden corrosion in steel plating and so on.
What you are asking for is impossible to achieve. You cannot build a boat without having critical structural components hidden. However, the margins of safety are so huge that like failures in any other stressed structure does not often lead to loss of either the structure or lives. Hence my comment that total failure is extremely rare and can invariably be traced to a series of failings in the use of the object.
I think one needs to keep a sense of proportion over these issues. When you have rare events you simple do not have enough data to draw anything other than broad conclusions, which I have done above. Otherwise the lessons are individual to the case. The number of recorded keel losses where there is enough detail to be useful takes you to only one conclusion. Do not bounce keels off hard seabeds (or whales!). The former can be avoided, the latter is random.
What annoys me is that just because a tiny minority of boats are treated in this way there seems to be a belief that it can happen to anyone who owns a similar boat. No it won't and there is no evidence to say that it has.
Very good points.
The boat was not fit for purpose.
Most of the findings in the MAIB report a speculation. Educated speculation, not fact.
The MAIB followed by the MCA & CPS are speculating the inner liner ladder had failed prior to departure.
Even the broken aft keel bolt is not conclusive the liner had failed due to the three known groundings.
At best it is very good speculation the keel bolt had failed at some point due to fatigue.
The MAIB refers to a common practice among sailing schools and examiners of light groundings. Based on other boats,
The keel might have failed due simply to a long hard life sailing hard.
If used as designed it would probably still be sailing.
The report indicates the keel did not suddenly fail catastrophicaly without warning.
The report indicates. The keel failed over a period of several hours while sailing hard on the open North Atlantic in near gale conditions.
It indicated the impending failure by leaking.
Had the boat been sailing within its code limit there would have been a very good chance the boat and crew would have made it to a safe port for repair.
No keels shouldn't fall off.
They very occasionaly do.
Who really understands all these varieties of codes.
I had no clue prior to this incident what any of them meant.
I had no reason to.
