In case it's any use to anyone other than me, I finally got a good
deal to courier my kayak to London from Dundee. I used:
J.R.S Logistics (Dundee) Ltd
Unit 1,Block 11 Nobel Rd,Wester Gourdie Ind Est
Dundee Angus
DD2 4UH
Tel: 01382 612020
They origonally quoted me 60 quid, but after much discussion I showed
them the boat and they took it for 20 quid! Fab.

I tried asking kayak stores, and their favoured couriers had stopped
taking kayaks! Red Star (railways) is now Lynx, who only talk to
Businesses - turds! I was even quoted 340 quid by one firm. It seem
that the uniformed dispatch centres and caged (container like) vans
are very efficient if you fit the nice package sizes they take, but if
you are a little off the norm, you're stuffed!

Thanks for all the help...
