I greatly appreciate your expert book on Get Rid of Boat Odors.--It would be immensely helpful to novices like myself to have a few accompanying sketches. ie: I think you said to use a 1" vent line running forward to just under the bow exited blow the hull/deck joint. I also noted that the vertical angle should be no higher than 45 degrees. That seems like a fairly shallow angle of incline, but i just want to be sure i had it right.
