@bigcockman you need to think how to wash and clean the kayak.
After use need to wash clean and dry before storage otherwise will smell.
Particularly sea water. All covered in sticky salt.
I do have two 2 man inflatable kayaks that we use for going on lakes. The leh cheh part is deflating clean and store. Must deflate till the air all out otherwise is bulky. The usual electric pumps dont do a very good job with deflating at the end part.
