We used to trip for seven days in a 15 foot Grumman. Later the trips got longer to two weeks and we needed a little more room. 16 would be ideal. 18.5 feet is really overkill for a week long trip but I realize the MN II is the favorite BWCA boat.
Speed on the water does not matter unless you single portage and have unloading, loading, down to a system of no waste of time. I wouldn't pay as much attention to the speed of the boat as to your speed.
I have the deep brethren to the MN II, the Odyssey and its been handy on two week unmaintained portage trips and on Lake Superior and remote far north trips. But not so necessary in the BWCA. Except as you get old. We could haul the Grumman easy in 1973 and did. Not anymore! We can still haul the Odyssey nearing the age of 70.
