Yr right Thom, a few sharp turns on the Del (just a bit further up the River
does a 90 deg turn in about 2500 feet). The wind gets swirling too, due to
all the obstructions (e.g., a mountainous landfill) so it seems to be coming
from all directions. The current gets strong too, and when passing under the
two bridges, especially the PA turnpike bridge, it feels like the sailboat
equivalent of "shooting the rapids." I've never been able to sail upriver
through these points without the tide's help (or motor-sailing).

(especially on that bend at St Mary's Hall)
You need a Vang that is also a "Preventer" It is cheaper and more
effective on your size boat.
