fin size and template also a very important component

Interesting.

One thing I noticed on a twin I had recently was that it felt like I lacked down the line projection after a bottom turn. I could get it to highline fine, but if I was dropping in straight, making a bottom turn and angling for the shoulder, there would be a hesitation in the boards acceleration.

It never felt too loose and I never felt like I had to baby my turns in any way. My fins were set 6" up from the tail and I tried 2 different sets (Akila's and Tomo's hatchet keel). Ultimately, I settled on the rationale that the center fin of a thruster wasn't just about hold, but it was also important in projecting down the line after a bottom turn. Not sure if my reasoning is faulty and there is another explanation??

I've been nervous to order another twin since.

I feel like I can push harder on a thruster so I generate more speed

When the wave has inherent speed, Twin is faster

If I was a better surfer, Id probably be more confident pushing a twin and be faster all the time on that

Basically, I think twin surfing is more advanced

Hey, Simon didn't call the design the thruster for no reason...:-) It surely is about thrust...ergo projection.

i rode nothing but quads for a long, long time and this past October started throwing some thrusters in my HPSB. as long as the wave has some push i can absolutely drive the board much harder with the thruster set-up.

it's interesting feeling the differences between quad vs. thruster in similar waves.

taking that one-step further a twin will definitely have less drive than a quad set-up so the difference between a thruster and twin will be pronounced and especially so to someone used to a thruster.

Bummer you guys can't get your Twins , 4 fins and Thrusters to work the best they can .

It does involve creating fins for each .

How else could this be possible .

Twins and quads are faster...in a straight line.

The thruster stabilizes the board's speed.

You can have the fastest vehicle on the planet but without traction the speed it can achieve is irrelevant.

At minimum the shaper should be able to direct you to a fin template for the board.

Also I've been surprised to hear how many shapers find fin placement irrelevant and do the exact same placement for every shape.

Do you think that's a function of a twin fin in general, or a twin with fins placed too far forward?


Both. If the fins are place too far forward, they slide. 6" shouldn't slide out.

The problem with twins is that they lack drive through a turn. I figured this out riding my current board w/o twinzer canards. Putting the canards in make the board project out of a bottom turn with way more speed. W/o canards, the board lagged out of the bottom turn and slow.

I haven't owned a thruster in about 10 years, rode quads for 5 years before switching to twinzers. Every time I jump on someone's thruster to try, it feels like I'm dragging kelp, but in a turn they feel good as long as I don't have to make my own speed (pump).

cheers

My suspicion is confirmed.

I should have also added that I didn't feel that same lag on the twinzer of yours that I surfed, but I also wasn't doing deep bottom turns on that day. More of a down-the-line takeoff.

I caught two shvt waves that day. Your board felt like one of my student's tiny boards when I used to trade w/ them (and I'm lighter than you).

Adding the canards makes a huge difference in hold and drive off the bottom or in a cutback.

To keep it Xanadu related, I had a custom hand shape by Xanadu in the early 90s. When my brother picked it up along w/ his board, Xanadu was proud/happy to tell him that mine was hand shaped.

It was the potato chip era, and I didn't get the drive out of it that I was getting at the time on my JCs, so I put it in the used rack at the surf shop I worked at. It was contest season and Taj Burrow ended up buying it as a backup (think he was on Webbers or MCs at the time). When I found out, I was a stoked grom. jam_on

Casa , can you give examples - no names tho

"Also I've been surprised to hear how many shapers find fin placement irrelevant and do the exact same placement for every shape."


It looked like this board worked the best yet for Noel .

Off to finish 40 fins for customs

Mayhem
JS
DHD

All use the same Tri fin placement for stock boards

Mayhem uses the same quad location on all but the retro end

JS has only 2 quad placements

DHD all the same every board
