I wasn't going to answer this but I am curious so here goes. ZZZZZippy, I am a senior member of the BCU (British Canoe Union) I hold level 5 instructor in sea kayaking, I run regular expeditions in the Hebrides (not going to commercialise with my site!!!) and have over 30 years experience in kayaking, starting in the marines as a diver/canoeist. I have run kayak survival courses, both in the service and civilian and I am also an experienced diver.
I have seen kayaks develop in shape and design over many years and I have paddled many of them, some in operations that were military orientated. I have owned many types of kayak including, ocean, perception, Prijon, etc, etc. I owe none of them any commercial favour, but I value my right to have my say.
I believe that I am reasonably astute when it comes to kayak knowledge and I would be grateful if you were to post your experience and qualifications regarding kayaking and all things marine, seeing as you have chosen to quote me as "knowing jack sh1t about kayaks"
Basically, put up or ZZZZZZZZZZip it
Just fully read your post / cr@p by the way!
For your information, its "swimmer / canoeist" not diver/canoeist in the role you mention! If you are gonna blag, get it RIGHT
