Here is the system that I have learned from my friend Alex. Most of you probably have a similar version and adapt it to your particular boat. My solo canoe is not very stable at rest so getting onto a platform at very low water levels a difficult process. This was also a problem when I arrived at a chickee with my touring kayak. It got so problematic for me that I refused to camp on these platforms when using the kayak. So for those that are balance impaired....my photobucket presentation:
This can be adapted to use with a touring kayak just keep the ropes centered and your weight towards the platform when standing.
Now if someone would post a picture or two of anchoring a boat away from the platfom using a trolley.
