Hi Tim,
Dont worry about size mate ,it sounds like im larger than you. There are several good kayaks which are designed for big guys and all the gear you wish to carry. Ive chosen the ocean kayak trident 15. Its load capacity is great at around250Kgs .Its nearly 16 Ft long so its fast,for a sit on top. Its very stable,wich allows you to concentrate on the fishing.It has several hatches,to stow gear below deck,ie tent etc. I could go on and on,the best thing would be to call around and have a look for yourself,or better still,try it out.
I live very close to the beach at Aberavon and use a trolley to take the kayak to the water. During the summer im normally on the water 4 or5 times a week ,so any time you like your more than welcome to give me a call,and we will sort something out. My E MAIL.........martinphillips007@sky.com
