Portaledge Discussion: Delta 2p vs Full Double D4

Imagine the redundancy as you lead/haul every 1/8th pitch of your easiest project

We will see who has the last laugh once me and the homies have occupied the Stovelegs in the OCTODOME (tm).

The NIAD'ers shrieks of horror will turn to songs of adoration once we offer tea and crumpets and a nice reprieve in the OCTODOME's sun room and backgammon parlor.

Perhaps there should be three or four of them on each of the classic routes?

Like a ski hut. 1st come 1st serve. looks cozy. like dinner ledge a day or two before anticipated inclement weather. 

Just gotta say, I really like where this is going (and also hope the OP got their ledge questions answered prior to thread drift).

Expect the IPO just in time for the spring thaw NIAD rush, barring any major R&D setbacks arising from quantum entanglements, bendy bars, or sewing booboos. OCTODOME, Inc. takes no responsibility for NIADs turning into month-long NIAPs once everyone realizes how cozy it is inside the OCTODOME.

I am a Delta 2p owner, it has been my first and only portaledge so far. I am pretty tall at 6'1" and have shared it with another climber on 7 nights. From my experience, it is pretty terrible to share, expect to snuggle, but maybe for smaller folks it is okay. I love the ledge, but felt a bit lied to with it advertised as a "2 person" ledge. I plan to get a second ledge for sharing at some point in the future.

What's the width of the 2p? I looked at Durango's website and they list the 2p at 52" wide and the D4 at 47" wide? That doesn't seem right if the D4 is bigger. What gives?

From John’s website dims of the delta2P. While technically the width is probably around 52, it’s only for a short time whereas I imaging the D4s is consistent throughout.

Ahhh I see. Thanks, Cameron

PSA to the OP: This D4 is likely still available. No affiliation with the seller. This is not the D4 scam that people have discussed around here, though of course you should do your own due diligence.

Were you utilizing a sling to the clip in point in the middle of the bed to raise up the bed? Having shared my Delta2p with a 6'+ partner for 11 nights, I'm confused by your "except to snuggle" as we were as seperate as you'll  be on a reg rectangular double ledge every night due to the raised clip in point creating effectively two seperate buckets, one for each climber to slide into ane away from their partner 

Never tried that... cant believe i didnt put that together. Still seems really small, but will test with my 6'4" friend as soon as I get the chance.

Thanks for the pointer!

For anyone curious I ended up getting the full Double D4 mainly because I was able to buy it used.

Making a ledge is 5% making the frame and 95% sewing. Even more so if you also make a fly. Think it all out carefully to save yourself hours and hours of frustration. Have fun! 

Hot tip of the day: buy cheap fabric and make at least one practice bed/fly. Don’t sweat it, you learn the mistakes and order of ops real quick.

What happened to that guy?  I heard he had a serious incident at the toupée salon?

It also depends on who made it, as I think some makers of the Delta 2P have different dimensions.

Another note, I would be cautious about this central connection as its sewn in a way that should be fine, but if you had it tensioned and “gave it what for” it might rip out. As I read his notes it appeared he was in between a fin and that tab, and it does make more sense with the tab but its not nearly as durable as a fin.

Buckle in.

The dims on bigwalls.net are centerline of tube, the stated dims for a finished ledge is the outer diameter. So you are losing a bit over an inch in width and 1.5” in length. The D2P is essentially an alpine double split down the diagonal and set shoulder to shoulder. 

D2P is more like the alpine double for two people side by side. The Full size D4 is different from the A5 Cliff Cabana in that the A5 had a straight line down the center, but the D4 has tapered head/foot arrangement. I don’t think this had ever changed for A5 cliff cabanas, which is odd. This means the D4 full size has ~25-27” of shoulder space vs the alpine double/d2P at around 22-23” inside the tubes. 

The end width of the D2P and the outer edge with of the D4 Full Size is sort of irrelevant since the constraint is where each person’s shoulders are.

I’ll have to check but I think DSS D2P might be different dims than Bigwalls.net dims. There’s at least 4 different D2P drawings on there, and its pretty easy for a ledge maker to measure it one way and come up with a ledge 1-2” shorter/longer in all directions.
