First, find the actual point along the curve of the wave you want, then you can ask for the direction of the wave at that time, and its point:
Thank you!
pair itime, iangle, boatpos; itime = (wave[3] intersectiontimes ((xpos,0)--(xpos,infinity))); iangle = direction (xpart itime) of wave[3]; boatpos = (point (xpart itime) of wave[3]) shifted (-5,0); % shift to center horizontally
There was still an error that I introduced:The boat on the first page is already way in, while on the last page it falls over the edge of the world.
I fixed several other things and drew a nicer boat. Feel free to use it. Hraban
