I tried the PVC roller idea but it didn't work for my cat. Up steep beaches they wouldn't roll but dug in and created point loads on the hulls, cracking the gelcoat. It found it better to use beach rollers strapped to the bows.

I have single and double handed camped in my Taipan 4.9. It is easy to right single handed but it is too lightweight for long term camping use. 96kg rigged (210 lbs)

I find it is safer to kayak when travelling solo, though I thinking of building a tacking outrigger as a camping boat that can be easily dragged up and down the beach. Something like Holopuni OC3 would be ideal but not cheap
