Not sure what chart you're looking at, but I suppose it depends on your 
definition of "most." The channels are in the 300 to 70 foot range until
you 
get past Alcatraz, then the channels drop to the 40-45' range toward the 
Richmond Bridge, but are deeper toward the Bay Bridge. Past the channel
line 
toward the Richmond Bridge, you're in the Southhampton Shoal and
Bezerkeley 
area, which is expansive, but shallow in the 10-15 ft range.

The Brothers are not in what I would consider the true north bay. They're 
just off San Pablo Strait, which is quite a way from the deep water 
channels, although that straight is a deep water channel that runs through

San Pablo Bay. Area-wise I suppose you can claim by total area the north
bay 
is quite shallow, but that doesn't really tell anyone much about the north

bay. I don't know of any major ****pping channels in this part of the bay 
that are "35" feet. More like 50% greater or more.

We were coming back up from Treasure Island from the Summer Sailstice to
Pt. 
Richmond. We got small swells and 5 ft. chop on a beam most of the trip. 
Depth was 10-15 or so after we cleared Treasure Island, where it was in
the 
high 30s, low 40s.

By the Gate toward Alcatraz, one can easily get decent size swells and 5+
ft 
chop.
