Geez, 11 days, single portage. A wee bit to much weight IMO. Not only does the fun factor sound like it might be reduced the "hurt" factor would rise.

Besides, with the lighter loads you are likely to breeze across as opposed to the big loads where you will likely be having to set stuff down before getting all the way. Thus probably not saving as much time as you think.

I typically run a fishing line (often pulling a deep crank with a big lip.....lots of drag on the boat) and I like to run the shoreline plus I always double on my portages and yet I still usually rack up a good day mileage wise.

Here's what I do to accomplish it.....I get up early, usually while it is still dark and eat and break camp and am often paddling while the mist is still on the water. That is a special time of day to be dipping a paddle trust me. All is still and quiet more often than not. This early start takes advantage of calm conditions when you can really roll 'cause as we all know it's gonna blow by 2. Then it is common for me to run late unless I'm worried about campsites. You can rack up some miles like this. I do like seeing new country. One bit of hard earned advice.....if you are a food stasher like me make sure you have a reflective marker to hang in the tree to mark your placement or else you may be "delayed". :P

Prouboy is right BTW, I'm not much fun around the campfire.  I'm usually in the sack shortly after dark if I'm not still fishing.
