Strakes

[NorfolkGreg]

I see single strakes, double strakes, strakes of varying heights above the waterline and different lengths. I assume they can be a good indication of what was felt best by each builder and are rarely changed by subsequent owner.
Would you challenge this idea?
I hope to create a page that would provide a spotter's guide to these "signature" features. I'd welcome photos of any boat that has a less common arrngement of strakes.
