Hi Fenlander..thanks for the feedback.. it helps give others a better view point rather than just my view.
I do stick with my thoughts and experiences with roller boats. However I can appreciate your different experiences and why you find transom wheels so useful. I have never been in the situation you describe where you have to tow your SIB by hand for such long distances and by the sounds of it..over tarmac pavements rather than shores. I would probably get a SIB suitable for transom wheels myself if I had to do that. I couldnít use my 4.3 Quicksilver either as its too heavy for me on my own with transom wheels.
Below is a typical type of place that I launch from and I hope you can appreciate transom wheels would be as much use as rubber oars in amongst the rocks. There is also a drop of two foot from the side of the road. I cant launch my 4.3m SIB there..so I take my 2.6m Seago. There was not another boat moving on Loch Leven on Friday..never mind folk fighting for the layby I parked in.
I didnít use roller boats either.. I inflate my SIB and then hold it on my back by grasping the seat. I must look like a giant tortoise on its hind legs..as I waddle across the boulders. I had a great day and will tell of that adventure shortly.. as well as post a photo of the deflated roller..probable Heinz Bean tin size ? but will let you see for yourself.
Sorry for the delay replying.. I was in the wilderness adventuring.... at Loch Leven
