I'm not sure if there's more to your question beyond "How do I get the NPW aloft fast?" and my lack of understanding concerns me. Aren't you the fellow looking to do some kiteboating?
Now, as to getting the NPW aloft fast, I have some land based solutions and a boat based solution.
Please read through these carefully before attempting them.

You'll need your NPW, the quad lines, the handles and two 12" tent pegs (you can get a package of four at a KMart or WalMart or any sports store for about US$5.00).
Please notice that I mentioned QUAD lines above even though what I'm about to tell you will sound like I'm describing dual line action. I'm suggesting you go with quad lines because in a sudden gust this kite really wants to be controlled and dual lines don't (in my opinion) provide the rapid control necessary.
Drive the tent pegs into the ground upwind of where you'll lay out the kite and about 2-3 feet apart from each other. I use lawn&garden gloves to drive the pegs in deep by hand, so that maybe 4" is above the ground. I also drive them in at an angle so that the pegs are about 30degrees from vertical in the ground. String up the handles (but not the kite yet) and place the handles around the pegs as if they were horseshoes and you'd just scored a ringer.
Now walk your lines out to where you'll launch the kite. Make sure your lines are straight and untwisted.
Open the NPW flat on the ground.
Find the kite's bottom lines first and attach these to the bottom lines from your handles. This is an important step. I prefer to attach bottom lines first  because there's no chance the kite will inflate and take off if the bottom lines are attached first. Attaching the top lines first means the kite has suddenly become a dual line kite with an unstable flight geometry and can be dangerous in the right kind of wind.
Once the bottom lines are attached attach the kite's top lines to the top lines from your handles.
Lay the kite out so that the top of the kite is about 1/4-1/3 curled over the rest of the kite.
Take one of the top lines in each hand and, facing the kite, walk backwards until you reach the handles.
With the NPW slightly folded over, a gentle pull on the top lines with the handles will get it airborne.  
In the above, it is important to remember that the tent pegs are there in case there's a sudden gust which does get the kite airborne.
The tent pegs give you a few minutes to think before you need to panic because the kite is lifting you off the ground.  

In a stronger wind (3-7mph) you will want to keep your workgloves with you as you tie the lines from the kite to the handle lines as described above.
When you get to the part above where I suggest you walk backwards, put your gloves on and then grab the lines. This much wind will inflate the NPW and you'll need to be a little sensitive to the wind as you walk backwards because you can "feather" the kite so that it stays inflated but doesn't get any lift until you get back to the handles.
Feathering means you provide just enough resistance to the kite's pull to keep it open and windward without giving enough resistance to get it airborne. If you've ever done anything like push-hands in T'ai Qi then you know what I mean, except now the wind is your partner and the kite is your partner's hands.
The gloves are necessary in case there's a sudden gust and the kite does get airborne, which now means the lines are running through your hands and having the gloves on will prevent you from getting burns and cuts from the line (trust me, the speed and power could seriously damage your hands without the gloves to protect them. Did I mention I use thick, canvas lawn&garden gloves?)
Also remember that you're only holding onto the top lines until you get to the handles or the handles get to you (I've had the tent pegs pulled from the ground several times. If you're not careful, the pegs get stuck in the lines and you'll know when they whack you in the spine). Holding onto only the top lines means you're flying a dual line kite until the you get to the handles.
Remember that dual line kites have different steering geometries and characteristics than quad line kites.  

First I need you to understand that I've never done any kiteboating (if that's your interest), nor have I flown the NPW in winds this strong (as of yet).  What I'm describing is based on other large kites (SkyTigers and CQuads) I've flown in strong winds and this is a method I think would work for you if you need to do a boat based launch. You'll need your gloves as described above. I have a jeep modified with tow hooks front and rear. I'm assuming a kiteboat has some kind of hooking mechanism or oarlocks or something which would server the same purpose. Vickee can sell you a harness (gelding harness, chastity belt, whatever it's called, Vickee'll know what I mean). I put on the harness then run a plastic covered cable (15' long, 500# breaking strength) through the back of the harness to the tow hooks on the jeep (usually the front because sometimes I fly at night and need the headlights to see what I'm doing).
I then take one handle and line set. I let the handle go to the ground, walk forward and slightly to the side about 3' with the lines in my hands, then let the lineset coil on the ground in about a 1' wide diameter coil.
Take the other handle and lineset and do the same, making sure the handles are about shoulder width apart, which means the linesets are coiled in front of you and are wider than your shoulders apart. Walk back between the two linesets and hook the handles into the harness (or into the oarlocks or whatever).
Walk back to the coiled linesets. Unlike the above methods, leave the NPW crumpled up into a ball and just free up the kite lines. As before, tie the bottom lines first then the top. You should now be standing in front of a ball of kite with the kites lines running behind you and attached to the coiled handle lines, which have some lines running to the handles which are attached to your harness. Put on your gloves. Hold the upper kite lines where you attached them to the upper handle lines. Shake the kite like you're shaking a beach towel to get rid of the sand. The kite will inflate. Let the lines run through your hands (remember, you're now controlling a DUAL LINE kite even though you have quad lines attached) and work the kite so it stays into the wind as the lines now pay themselves out. Do this slowly so that the coiled lines don't twist up. Eventually you'll run out of coiled linesets and you'll get a snap when the lines pull on the handles you've attached to your harness. Be sure your insurance is paid up because you're in for one heck of a ride. LAST NOTE: I think this method would work for a boat launch in a light wind and would love to hear your thoughts on it. Remember, I've never flown the NPW in a very strong wind and I've only used this technique on other very large kites (simply haven't had the wind to do this with the NPW yet).

This is neither an endorsement nor an encouragement!

Since writing this original page I've had a chance to take the NPW out in a wind that only a fool or an idiot would go out in (steady winds over 17mph with gusts to 23mph). The easiest way to get the NPW airborne (like you could stop it!) was to feather as described above but using the bottom lines. This forced the NPW to remain deflated until I was in position and securely harnessed(!!!).

There you go, friends. I hope this has been helpful. With about a day's practice you'll be able to get any large power kite (dual or quad line) airborne using these methods in very quick time. With winds 5-7mph I'll get kites up in less than 30 seconds (after I've run out the lines, etc.). In stronger winds it can take longer to launch because some kites will self-launch until you get the hang of feathering them (described above). It can also take longer in very light winds but only because the NPW is sensitive to the wind's angle of attack. It wants winds around 3-5mph or better to get it above 30degrees from the horizon, but anything beyond that might be too high (maybe) if you're kiteboating.

Good flying, friends.

Enjoy and fly safe.
