: I've been looking over greywuuf's posts about his experiences so
: far building his Yost Sea Tour 15 EXP. His first post went over
: how to determine the correct height above the baseline for the
: stations/formers... and how to relate the baseline to the
: strongback.

: I think I understand the process... using Yost's example of the Sea
: Ranger, the keel of stations #1 and #8 are both 2.7 cm above the
: baseline ( http://yostwerks.com/SeaRanger2.html ). Station #4's
: keel is right at the baseline, per the table of offsets.

: At http://www.yostwerks.com/Frame2.html , Tom explains that he's
: set the baseline at 3" above the strongback. That pushes
: the keels of stations #1 and #8 to 4" above the strongback
: (~2.7 cm above the baseline). Tom goes on to explain in step #5
: that he anchors the keel at the low point at 3" above the
: strongback (at the baseline)... 8.5' from the bow.

: Where does he get the 8.5' measurement? I don't see it listed
: anywhere in the table of offsets, nor anywhere else on the page.
: I know section #4 has the keel at the 0" HAB point. If I
: add up the cross section spacing from the bow to section #4, I
: get 8.25 feet. It's not much of a difference, but I'm used to
: building model aircraft... small changes can make big changes in
: flight behavior. That's assuming the rocker is a big detail.

: I do note that the distance from the bow to the first station is
: 36"+. I seem to remember him saying that the distance to
: the bow can vary depending on how the bow plate
: "looks"... so if he extended the slope of the plate,
: which pushed the bow out by 0.25'... then measured the distance
: to station #4 afterwards for his web site afterwards.

I'd suggest asking Tom. He's always been helpful with email questions in the past.
