73CM UHM Mast finally arrived. What a pleasant surprise after waiting since Fall of 25. Def less drag, going to be fun for trash bag and DW. But loved it in the surf, def could tell I was getting snappier turns on my SF830 and 680. Didn’t wear my watch but it was feeling faster as well on jumps and broad reaches. Pretty much the same results that people are feeling on lots of UHM’s.


Just an update. I knew the mast felt more nervous but after wearing the watch a couple of runs the Mast is def 1.5-2 knots faster. Hard to be precise and sail exactly the same especially in waves but it was pretty obvious. My turns are also tighter

I'm enjoying my SF 930 and 680 combo for winging our high desert thermals. I was on the MA 850 as my primary foil last season. The SF foils have really helped me start making my tacks more consistently. What tails are folks using with the 930 and 680. I've been on the 208 and 178. Thinking about picking up the 145 for more glide. Interested in hearing about what tails others like with the SF foils. Thanx, Mike


The 142 will give you more glide, the 145 more pump and turning. Either will spice things up from the 178.

I'm on the S145v2 and the S122 with both those foils, mix between 60/70 fuse. Have not even considered putting a larger stab back on. 145 for pump and carving, 122 for pump and glide, although it does reduce the low end a little bit for take-off, once up though it stays up. If I could only have one - S145 all day.

Ordered the S145 over the weekend. Looking forward to trying it out later this week. Also glad to hear it might pair well with both the 930 and 680. Appreciate the replies ! Hard to get much info on the north foils
