Chopped HS1550 is Now a ....

Continuing on the "working on foils" theme of my Sunday, I figured out the surface area of the chopped down HS1550.

I wasn't too far off when I guessed 1475.  So from this point forward, I'll call this wing the HS1420CS.

Dawn Patrol - 3/27/2021

Marlon and I hit the dawn patrol this morning.  We drove separately as Marlon had volunteered to help guide students in an activity one of his previous professors was working on,  There was a little texture on the water, the swell was decent (waist - mostly, to chest - occasionally), and the tide was coming down from a high of 1.1'.  As you can see below, Marlon brought his longboard.  Once he paddled out, I didn't see him.

I brought both of the recently chopped foils out.  I started out with the HS1532CS.  The foil has settled in - no more groans from rough spots holding water, no more slipping from the wax coat, and it glides and pumps with zero issues.  I caught a bunch of waves, then figured I'd paddle in.  If it was early enough still (I had to be back home by 9 so I could take Noe to sailing) I'd paddled back out with the chopped 1550.

Well - it was early enough so back out I went.  Riding this foil is a completely different experience - has some of the glide, some of the pump, but how it moves on a wave... perfection!!!  I caught three really good waves - pulling off some really hard turns and being able to go top to bottom on a wave face.  This front foil makes prone foiling just like shortboard surfing.  My search for the perfect surf foil is over - at least for waves chest high and under.  Above that, I think the CF1200 will be the go to (come on south swells!!!).

 

So the front foils are starting to get stratified - the HS1850, HS1532CS, HS1250 (and maybe eventually the CF800 - oddball) are better for winging.  With their flatter, wider shape, they seem to be better for getting up faster with the wing.  The HS1550, HS1475 (what I'm calling it for now until I can measure the surface area), CF1200 (and again the oddball CF800) are the surf foils.  Primarily the shorter width, more swept back tips all carve up a wave face.  These don't need the same efficiency to stay on foil since they get all the power they need from the wave.  Now I can stop fidgeting with all this stuff (not likely).

Finished Sanding the Chopped Front Foils

La and I ran some errands in the afternoon - and when I got back I ran the front foils through the 80-120-180-220-320 sanding grits.  After that, I then wet sanded through 320-400-500-1000-1500.

I sanded out the spots where the foil name was - so when I figure out what to call these two, I can write the designator in these spots.  I think the leading name candidates are CHS1475PF (Prone Foil) and CHS1600W (Wing)

They came out really nice!  I weighed them both for future reference - CHS1475PF is 36.7 ounces, the CHS1600W is 47.4 ounces.

Now the debate is whether to wax them, or just leave them be.

Chop Shop Fest - 1850 to 1600, 1550 to 1475

After Marlon and I got home, and after we ate lunch, I headed out to the garage to cut down the two foils I had prepared the other night.  I started with the 1550 (since this is the third one I've chopped).  I got lucky as heck - no foam exposed on the cut line, or even on the refoiled sections (that has never happened on any of the previous chops).

I nailed this one!

Next I headed into uncharted territory - chopping the HS1850.  I got lucky twice in a row - no foam core exposed during the cut, or even in the refoiling.

This wing looks so much better than the original.  Truth be known, the inspiration for this was the specifications on the new upcoming HS1550v2.  It is only 2 mm shorter in wingspan than the HS1850.  That means the chord was the target change.  Like I had posted before, I figured the new surface area is right around 1600 cm2.

These both came out really nice!  I still need to sand the higher grits, wet sand, re-label and then clear coat these before I can use them.

I still see a place for the HS1850 (especially for winging lighter days), but I can't wait to try out this Chopped HS1600 and the Chopped HS1475!
