I use the following gear:
Black custom modified carbon-kevlar kayak based on the first version of the Sea Bird Designs North Sea kayak. The kayak that is currently sold by Seabird Designs is a newer and better version: http://seabirddesigns.com/kayaks/north-sea
For rough water use, I have an orange NDK Romany Classic: http://www.seakayakinguk.com/seakayaks/?mode=range&item=ROMANY
