Arizona | Is there any consensus regarding what tramp attachment sys works best?
Bolt ropes pull out
Slugs put uneven pressure and point load on bolt track
Fiberglass rod with strip of tramp material and lacing to tramp
others?

Roanoke Island ,N.C. | Mine has rope with strap tabs. Ff you sand the edge of the groove until it's rounded and smooth it works great. Only complaint I've heard was the straps being cut , so I fixed what was cutting them instead of reinventing the wheel.

Arizona | The system on my boat I think is the best. Its the kind with the strips of webbing that run the length of the slot with a fiberglass rod backing the laces. I've had all three systems on the boat and this one is the best. Just make sure that the webbing ends are reinforced because they will fray there. I've got pictures of the system on the f20 forum somewhere. I cant see the pics on your I20 forum post. Can you repost them ? Again, something made or something bought?

Mine came with the tramp from perf. catamarans, but all it is is a piece of line with a 1" wide webbing strap sewed around it creating a loop for the tramp tension line to pass through. A sailmaker or canvas/awning shop could do it for you pretty easily.

Roanoke Island ,N.C. | Here you go: ![[Linked Image]](https://lh6.googleusercontent.com/-QQubE9nonVM/TMbdFWCa47I/AAAAAAAAQBg/ZGNRknHZnrM/s800/2010-10-26_09-50-44_769.jpg) ![[Linked Image]](https://lh4.googleusercontent.com/-SR0DeuhQ9lU/TMbdYSAQPhI/AAAAAAAAQBg/UGWE43XNUuw/s800/2010-10-26_09-51-14_904.jpg) The problem I see here is that you are defeating the purpose of the side lace tramp by refilling half the "space" for air escape(and the heel of your foot), with more solid material. If I had to do mine over again I'd cut another 3" or 4" off the sides of the tramp.

Roanoke Island ,N.C. | The purpose of the side laced tramp was to fix the problem with the original tramp which was the bolt rope pulling out. All great,all knowing one. Wrong again, but there ain't no tellin' you nothin. p.s. The real solution to your original tramp pulling out was a second layer of material or put down the case of twinkies.

Naples, FL | looking at the picture, I kinda wonder why both sides don't have that fiberglass rod? It would seem to me that might allow for more even distribution of force than the little straps on the tramp side?
And not knowing the "real" reason why they switched, how much air can move through that slot? The boat still goes pretty fast on its side with the new tramp design, don't ask me how I know....

42.904444 N; 88.008586 W | Lately I've mostly seen the tramp cut back, webbing loops, and the line (usually spectra, etc.) looped around larger rounded screw heads that stick up on the hull near the old slot wjhere the tramp used to go in to. the slot is glassed over. Just what I've seen/sailed on as recent as last weekend.

Roanoke Island ,N.C. | Oh yeah I forgot Todd knows everything about everything. My tramp was plenty tight back when it was the solid side style... it just pulled out at the back corners if you looked at it hard enough.
Telling a type 1 diabetic to lay off Twinkies is great todd. You should have been a ****ing doctor you know. You realize back when we had the one piece tramp I was 175 lbs? Whether or not it was the primary reason for going to the side lacing or not, it was more than common for the bolt rope to pull out on the solid tramp style. We tried everything to keep it on place.. nothing worked. We even put a fiberglass rod up in the slot and that couldn't even keep it in there.
Whatever crazy reason you think it was developed, I know the reason we switched was because the stupid tramp wasn't staying on the boat. I think that's a pretty damn good reason personally. Tad, tell the truth. You got your new tramp 'cuz Trey told you to. Doctor Todd says "Don't forget your meds,it sounds like you already did." I may not know much, but I do know the history of the I/N-20. p.s. Wait until that rod gets a hold of your leg in a pitchpole. We'll have a Shish-ka-Tad. p.s.s. Didn't know you were so serious about your Twinkies. It's not like I told you lay off the man sausage. Sorry I forgot the smiley faces.

Jay, It's so the air can get out while you're sailing, not for capsizes. You can feel the air rushing through, vertically. And Yes, Nacra/E/P dropped the ball on that also. It should have been wider.

Naples, FL | is there a maximum allowable width to this slot? Not that I want to stick my foot there in a panic.... Too bad that air couldn't be used as a cushion like a hovercraft. Even a little pressure would help, right?

Portland, Maine | Tad, tell the truth. You got your new tramp 'cuz Trey told you to. Of course he did. Which is why he told me to fill in the rails and just convert to the screw system before I inquired with Krantz about a simpler solution - which was this. On a site note, Trey also tells me when to wipe my butt. Doctor Todd says "Don't forget your meds,it sounds like you already did." Kind of hard to forget to take it. I have a device on my arm that gives it to me constantly. Finally, something I can agree with :P p.s. Wait until that rod gets a hold of your leg in a pitchpole. We'll have a Shish-ka-Tad. The rod ends can be trimmed easily with a dremel once they're installed. I'd worry much more about hitting a raised board or getting cheese sliced on the shrouds.
