Hello all, I'm still ISO a 5.7 and would like to know the difference, if any, between a 5.7 and 570 other than the 570 being newer? Does anyone know of a Nacra dealer in the Chesapeake Bay?

The 570 would have the Inter rudder system which is a good upgrade. The beams are a D shape. You may have a different jib halyard system as well.

The 570 uses a "blade" jib, I'm not sure if the self tacking is standard or an option. IIRC most of the 570's were also set up for a spin.
At this site you can see both manuals & go over each in detail
http://www.nacrasailing.c…download/nacradownloads/
Nacra Manuals will open up a sub menu where you will see the 570 & the 5.7 under "Vintage"
The older Nacra manuals are also here at The Beachcats, in albums, Technical, pg 5.

No Nacra dealer in the Chesapeake area. Where are you located? Consider a Nacra 20 and come sail/race in Galesville/Annapolis?
Rick Bliss @ New England Catamarans is the go-to dealer for all things Nacra. -

If u take a close look at both model nacras 570&5.7 side by side u will note a slight diference in the hull shape and design, it's almost imperceptible. The 570 is an updated modified 5.7 with square top main and smaller jib-but slightly faster, back of hull also slightly smaller/narrower. 570 comes with port holes with srew off tops aft of tramp. The rudder system is updated on 570 the whole system is removable- u can lift up and disconnect entire system tiller connector bar and 2 rudders and castings(which r smaller lighter than on 5.7) mast on 570 feels like its 35lbs lighter than 5.7 and as noted by prior comment by bacho xbeams diiffer in u verses round shape r lighter,an upgrade, however 5.7 beams interchangeable with 5.2 beams and or other older nacras. I could be wrong since dolphin striker assembly looks the same on both cats but newer 570 appears to hold up better perhaps because mast is lighter. Both cats require a lot of sailing acumen to single hand in high winds
