I'm totally serious about my formula, but the exact numbers will depend on the variables. Give me the footprint of a large boat and its average speed and I'll figure out how many of my sea kayaks it equals.

Of course speed is a factor! The amount of lake that you're using in a given time period is water that another boat can't use in that same time period.

Perhaps this will help: change the word "using" to "consuming."

Evenstar: As has already been said, one 30' boat uses 30' of lake at a time. One hundred 10' boats use 1000' of lake at a time

A boat does not "consume" water. By consuming you would mean that once a boat passed through a particular area of water, no other vessel could use that water.

Dictionary.com Consume - –verb (used with object) 1. to destroy or expend by use; use up.
2. to eat or drink up; devour.
3. to destroy, as by decomposition or burning: Fire consumed the forest.
4. to spend (money, time, etc.) wastefully.
5. to absorb; engross: consumed with curiosity.
–verb (used without object) 6. to undergo destruction; waste away.
7. to use or use up consumer goods.

The area of water that a boat occupies is based on its length, width, and height. And during the period of time that a boat occupies that area obviously no other boat can occupy the same space. But the boat doesn't consume that area, otherwise there would be a big hole in the lake after the boat passes. So while a faster boat would be able to go more places in a given period of time, it would not restrict another boat from going to the same places at a slower speed. This is why I don't understand how this gets pulled into the speed limit debate. And as I said in my last post the only impact a faster boat would have on other boaters is crossing bow to bow, or if a faster boat ran up on the stern of a slower boat. And "faster" is a relative term, since the "faster" boat only has to be going faster than the boats around it. Other than that a boat traveling at a slower speed actually consumes (to ues your term) a particular area of water longer than a faster boat. The worst offender of using a particualr area of lake would be someone at anchor, because no one else can use that particular piece of water until they move. So a larger boat anchored would have a very large "Lake Footprint" because there could be many kayaks floating in the same spot. If you had the ability to stop time and freeze all the boats on the lake. The boat going 100mph would not be consuming anymore of the lake than the same sized boat at anchor.

If there are 100 boats on the lake, each with its own 150 ft circle around it...how can that possibly take up more of the "lake footprint" than 1 boat with a single 150 ft circle around it?

Lets make a couple assumptions, then some calculations based on those.

1. A smaller "family" boat is a 23 ft bowrider. Average width might be 8 ft. You could say that the boat occupies 184 square feet (23 ft long x 8 ft wide). Not exactly accurate, but close enough.
2. A larger "fast" boat is a 32 footer. Average with probably about the same 8 ft. You could say that this boat occupies 256 square feet (32 ft long x 8 ft wide).

3. 100 smaller boats, each occupying 184 square feet, occupy 18,400 square feet (100 boats x 184 sf). This does not take into account the 150 ft circle around each. Sorry, that math is too much for me. Let's just pretend they are all rafting.
4. 1 larger fast boat occupies 256 sf, as determined above. Same 150 ft circle too.

Conclusion-The 100 smaller boats occupy 18,144 FEWER square feet than 1 single larger boat...again, not taking the 150 ft circle into consideration (18,400-256).

So tell me again...how does 1 large boat have a larger footprint than 100 smaller boats?
