I remember reading about baidarka sterns somewhere... I think it was it here: http://books.google.com/books?id=oGFHP-79tnQC&pg=PA14&lpg=PA14&dq=baidarka+stern+wake&source=bl&ots=2OIpGrp4dl&sig=oxJVayNqHj2Um9_OmAnno8je4js&hl=en&ei=_CuiTfXAIYHegQe0sKHkBQ&sa=X&oi=book_result&ct=result&resnum=1&ved=0CBUQ6AEwAA#v=onepage&q=baidarka%20stern%20wake&f=false

Might that answer your question?

: g'day all,
: The baidarka i'm paddling at the moment throws up a substantial
: amount of stern wave at around 5-6 knots. ( seemingly over an
: inch and maybe two inches wave height).
: Having never seen another baidarka in the flesh, my question is; is
: the stern wake of a baidarka meant to be smooth and almost
: imperceptible? or is this normal?
: I worry that this is all causing too much drag...... but i'm no
: hydrodynamicist.
: thanks, tippy
