Uhhh "sab wood" is actually "sap wood" and sap wood is typically considered
the "juvenile" wood that makes up the outer "skin" of a tree (the layers
just under the bark) whose purpose is to carry sap to the canopy. Heartwood
is found nearer the center of the tree and does not carry wood and as such,
tends to be far more stable and darker in colour. "typical" hardwood found
in boats/fine furniture is heartwood. Regardless, that's not what "white
wood" is.

White wood is a mix of whatever softwood the mill happens to be running at
that time. Pine, fir, hemlock, balsam etc....all are classified as white
wood. As for boat building/repairing and Lowes/Home Depot, don't mix them.
The lumber you get at any big-box will simply not be suitable for marine
use. Actually, it's rarely suitable for anything other than fence building
and even that's questionable..

If you need to purchase wood for marine repairs, do so from a reputable
supplier of product designed/procured for that purpose. If none are in your
neighborhood, there are many good sources via the mail. Here's a great place
to start.

By the way, what is "white wood" anway???

Sab wood ?
The outher rings of quite a few species are useless for boat boulding ,
where
others species like spruce , you acturly prefere the sab (sap) wood .
With Oak the white wood will be the sab wood that you cut off in boat
building.
Acturly chemical wood protection, was kind of invented to make the whole
tree
usefull including the useless sabwood.
