Transport sea or land, carry not based on weight

[Brygun]

One of the current things (if it still is) is that how much a boat or raft could carry was done as multipler of the weight. While simple its full inaccuracies.

For instance if you hollow out a log (modded BAC option) you reduce the weight of the log by XXX which is how much load you should gain (carrying you and your stuff in the hollowed out space). In stead the dug out log loses capacity as its own weight is down.

The BAC has some suggestions for intended floatation of objects.

I was thinking with the upcoming land carry like a travois that it would need the same thing. If the land code could get then could the same changes be made to the water code.

That I would hope for is objects for sea/land have:

Is boat? yes/no
Is land load helper? yes/no

Weight of object
Volume of the object internal
Load reduction
Flotation of the object (includes itself)

You could then have a 200 lb log that could float 400 lbs (available of 200) then dig it out to be...

100 lb dug out
100 lb internal volume
Floatation of 400 (available 300)

Rafts might not change the % load for propulsion but perhaps better punts might.

Likewise  a bag has (example figures)
2 lb item weight
20 lb volume
20 lb flotation (if you filled it up with air)
0 % load reduction

But if you make a bag with strap perhaps
3 lb item weight
20 lb volume
20 lb flotation (if you filled it up with air)
50 % load reduction

[PALU]

As far as I understand the inflated carrying capacity is a work around for the inability to pull logs after a water craft rather than loading them onto it. If realistic carrying capacities were used you wouldn't be able to use rivers to move logs (well, you might load one or so onto a raft).

Well a bowl floats as it displaces more water than it weighs. A real world bowl might weigh 1 lb but displace enough water to hold 5 without flooding the bowl.

The thing is things have a different ratio between their weight and how much they float.  For example a log floats around 50% its volume so a 500 lb log could carry 500 lbs of non log.

Hollow that log out and you can not lose capacity. A dug out canoe might weigh 100 lbs so it should carry now 900 lbs (500 + 400)

There isn't a simple ratio and right now its a one ratio for all boats.

Towing floatables, like trunks and logs, is a separate issue.
