Rear Corner Skirt Attachment

Post by gone7 » May 1st, 2012, 11:05 pm

Hello,

I'm curious about the placement of the rear skirt attachment from where it transitions from the upper side attachment line to the rear upper attachment line. The height drops and I've seen on several crafts where it makes a nice curve from one to the next. My plans are dated from "04" and I can't seem to find any mention of this on them. Is it hidden in there someplace? If not can you give me some relative measurements for making this transition? When do you begin the arc from the top of the side panel and is there a certain radius suggested?

Thanks,

It is just done by eye. Try using a thin ruler as a batten.

Alright, sounds like it isn't very critical. It looks like it's roughly a 45 degree angle but with a slight curve. Thanks Bryan!

Remember, that part of the skirt is just a fill panel from the hinged side extension to the hull. Its geometry isn't critical.

Thanks John,

I do realize that it connects to the end of the hinged extension but since there doesn't seem to be any note in the plans on the best place to begin the attachment angle on the hull I thought I'd ask. In fact the plans don't mention anything about building in hardpoints along this angle. Since it doesn't seem super critical I can work something out. But for the sake of discussion, obviously a person might be wrong to begin that angle on the hull at a location which is anything less than 90 degrees forward from the end of the hinged extension. And if a person had no slope there at all and dropped directly down at the end of the H15 (side) panel I would think that would look kinda strange once it inflated leaving an odd bulge. So, if these limitations are true then there really is a measurement to consider. I know it wouldn't be critical for the function of the craft but it seems like it would effect the look of how the end of that fill panel transitions into the bag portion of the skirt. Since I've built several of these before I don't feel too "at risk" in just doing what seems like the right thing to do, but for a new builder I think it would be helpful to include some kind of a note in the plans for this (for example: "Not critical beyond a certain measurement on the hull. Previous builders have experienced good results by beginning the transition at approximately a 45 degree angle from the rear. Add hardpoints along this line." )

The plans simply show the H15 panel with a skirt attachment line continuing all the way along the top of the panel, and then an adjoining H12 panel with the skirt contact line suddenly at the bottom (a drop of 8") and no explanation or means of how to transition from one to the next. But that's why this forum makes good sense. If there's something that's not easy to understand in the plans then it will probably be discussed here. ;)

Yep!! I agree this is a great place to discuss some of the 'finer' points of building a SEV ;)

Now getting it to bend that pretty is another story! ;)
