boat tail for saturn
 
Hello everyone, I want to boat tail my saturn. I would like to just build it off of my trunk instead of from the roofline. Would I be wasting my time to build a boat tail of that nature?

does this look right?

Looks right. I'd think such a boattail would provide effectiveness somewhere between that of a Bonneville spoiler and a full boattail.

I decided that I might as well just build a real boat tail. I have a piece of plexi that I got for free so figuring thats about the most expensive part I might as well just go all out. I Think I would like to cut it off at the 50 degree line. Any suggestions on an angle coming from the rear bumper?

hows this look....too steep for the bottom?

Frank Lee 05-21-2011 07:09 PM

I think so.

My earlier contribution for a 3rd-gen agrees with your center of roof camber :

I'd go look at the aerocivic for what his choice was for the bottom angle.

after an evening of staring at the back end of a saturn I decided that right now I dont want to deal with it. I see why most boat tails are done to hatch backs. Kind of an easy canvas to work from compared to a sedan. I might just go with a spoiler that reaches out and touches the overlay. any ideas on angles for that? If I did go with a boat tail I think I would just keep my sides vertical and they would look like they would come straight up out of the trunk and then straight back from there. Working around all of the goofy angles on that car is more than I want to deal with at the moment.

Anywhere from 0 (horizontal) to 30 deg up I guess. At 0 it'll stick further out the back but it should leave less trailing wake area thus be more effective. At 30 it'll stick up and get in your rearward vision but it'll intersect the template curve without sticking so far out the back- and of course it'll leave a larger trailing wake area but still be better than nothing.

I made this for the other 3rd-gen owner too :
