After a year on the HG I76, I purchased the PFI 730 lower and W103 carbon mast. The mast was coming a couple weeks after the lower, so I got the Phantasm fuse to HG mast adapter so I could test the components individually. I honestly never had any complaints with the stiffness of the HG mast, but its also the only system I've ever ridden, so no comparison for reference.
PF1730 and HG 90cm aluminun mast.
The PFI 730 still has the wide speed range, easy launch of the 76 but feels more "floaty" and not the "locked in" feeling of the 76. Make sense with lower surface area. Moved the foil mast further forward as the sail base pressure would drive the nose down quicker. Once I got the pitch balance sorted, control was easier. In lighter upwind, the 76 felt like it would point higher but get hard to control lift when overpowered. The 730 felt better in those situations. Going off the wind is where things interasting. The 730 "feels" faster but without a doubt has a ton more glide than the 76 without the tendency to rise as speeds increase.
On the 76 I stay on the gas as much as possible throgh the jibe. Stay switchfoot until the cambers are rotated and powered up before the foot switch. The 730 has so much glide in high speed jibe, I'm in the straps headed the other direction before rotating the cambers and powering up.
Sheeting in and bearing off downwind on the 730 was fast, but sketchy to control in like powered up broad reach going for speed.

Ok, this is an absolute mind blower in control !!.
This changes everything. This platform is rock solid. Like standing on a sidewalk compared to the 90 aluminum mast. Everything is so much easier in wigh wind/wave situations. The extra length and stiffness charging upwind through deep chop requires less effort, and easier to keep the nose down. Off the wind is an absolute blast. No over foiling at high speeds. Way easier to control than the HG. Where I used to "I'm gonna wait for that insane puff pass by before I bear off", now I sheet in hard and send it !.
Bottom line..
Both kits (Hoverglide and Phantasm) work very well together as designed, but to get the full potential of the Phantasm, the new Mast is a must IMO.
Nice looking setup - slingshot have come a long way since I got my AL mast set pre-covid!
Wsurfaustin glad you like your pfi730 and new mast I bought the Same about 6 weeks ago although the wind has been to light to get much time on it I have tryed it with a 6m and it feels solid under foot to the point it feels unmonverable
What size sails are you using and where are you positioned with mast base and foil base in the track
Thanks for any help
Very nice set up, I can tell you are already stoked with it.
The mast is so important and there is nothing like the phantasm 12k mast, soooo stiff....great choice

I use 3.7,4.5,and 5.2 sails
I have both my sail mast base and foil mast all the back. When I say back, i mean the track nut with 100% overlap so as not to pop out of the track, so as far back as it can go.
I'm 5'8" 30" inseam, 140lbs and apeish arms for reference

Ya, I'm blown away at what a difference the mast makes.

So far I have only used the 6m sail in the centre of the mast track.
The foil mast I'm placing in the box so I can see 4 on the scale at the back (slingshot 114)
5'8" tall 168lbs
I will try bringing the sail back
Hoping for windier days to use smaller sails

Best of luck on the wind seaanchor. High wind and small sails are a blast. So light and easy to handle. Duck jibes are a lot easier also. I've only been out a few times on the new mast with phantasm, but so far my highest speed was on the 3.7 sail @20.8 knots in 25 knot wind.
