Ha ha Pugs!! I feel I am in your esteemed territory now mate, and you won't have to humble yourself too much. Now its your turn again!!!

Well done Pugs and Wayne 2nd fastest 2sec and 5 x 10!!!

Big team outing! A swag of PBs!

WOW PB's galore super effort  , its stinking hot & windless here

Hi Adrian. Definately requires a weedy, and a shallow one at that. The MUF delta's are the go to get the best out of this spot. They allow you to get right up in the weed beds where the water is as flat as you will find anywhere. Also requires patience to walk through stinky mud and weed!!! Great spot though mate, worth the effort for sure!

Oops... I deleted my original post. Sorry for confusion.

I have a Isonic 97 and use sails 5.8-7.2 on it. Which MUF Delta should I get, and can anyone suggest where to buy one?  Looking above, it seems that around 20-21cm is the go?

Cheers!

Adrian dont be tempted to go too small on the isonic 97, as it has a fairly wide tail.   I had a MUF Weed Speed (non-delta) 24cm on my is97 and it was too small.

by the way, nice speeds everywhere marauders!  see you soon.

Well done Jamie on the swag of PBs. Sorry I forgot to mention you earlier. My bad.

And well done to all the other team members who put in a big effort on Wednesday.

I have an old Finworks 10.5" weed fin tha I used on an Extreme B&J board. Maybe I should try that first. It would be on the small side for the i97 but may be enough in strong conditions.

If buying, I guess the MUF 21 Slalom Delta might be the way to go. Seems to be getting used to good effect here on larger volume and width boards than mine, and I am guessing these type of fins would no tail walk when overpowered as much as a slalom fin, so if a little large you just lose a little speed???

Hey Adrian, I sail in a spot that requires the exclusive use of of the Deltas. I use a 19cm Delta with a 105l board(63cmW) and KA Koncept.6.6. I have never had it let go and spin out on smooth water.( So much so i am going to get a 17cm Delta.) However it is a real handful in short sharp chop and at times almost impossible if overpowered.So IMHO it might be a case of how much time will you be spending on chop. Also because the lift off the fin at slow speed is rubbish, a bigger board can be of benefit when getting planing. In my spot because its a bit abrasive and i and I am a bit obsessive about keeping my fins smooth they do wear down with use - my fin was a 21cm originally! Otherwise all the pros/cons you see about Deltas I think hold true- they are certainly different to use and require a different approach to your back foot. For me they are brilliant in their intended environment, but not so good anywhere else. Apologies if I am telling you stuff you already know. Get one and then go crashing into stuff :-)

Incredible team turn out guys (18 in total ) and congrats on the PB's.

Thanks fangman... just the sought of info I am after. Sounds like maybe the 20 would be the go. I only intend to use that board and fin combo when going for max speed on shallow weed beds. I generally don't sail in weed normally unless it is on the central coast lakes which I specifically go to for flat water. Just one question... what happens with these fins if you go too large? So say I get a 21 and use it with a 5.8 in nuking wind, do they get overpowered like normal fins and try to tail walk etc... or is it just a touch slower due to more drag?

I use a 21 Delta on a 105 L and 65 wide board. Its heaps of fin. i have had no problems spinning out or going upwind. If really struggling upwind, i just bring my back foot out of the strap and forward and she sits up nicely and goes. Had a few problems first time I used it in rougher water, but you adjust pretty quick.

Based on all that, i am going to get an 18 Delta for same board for windier days.

I dont know Adrian, I havent ever experienced any issues like that, but perhaps I have not ever been in windy enough conditions or I am just too fat?? I am no expert on fins, but I think part of the problem that causes tail walk is that the fin flexes down near the tip. Because deltas are short and therefore very stiff they will not flex to the same degree (if at all - I just had a crack at bending mine and I could not get it to flex at all). So my educated guess is that if you are over finned you will be slower because of increased surface area on the fin, but I dont think tail walk will be an issue. It would be good to hear if anyone has had this happen with a Delta??.

Welldone on the odometer Steve, huge Ks. Kicken ass all!!! Yeh Delta's are the go. Body weight board and sail size definately determines size of fin. Me 88kg 59 wide 92l 6.6 koncept 18 delta fin would be the smallest id go and I think would best maximise that set up and gave me my Pb's. Ive used in 82l Patrik same fin and sail and felt heaps flighty with similar speed. In flat water, patrik board 5.7 sail 15 delta i reckon will be sweeet. Bigger guys over 105 could go 20 cm with 7.5 100l 70 wide and kill it like Matty D. Wider the tail of the board the bigger the fin needed. Great fins, and has sent us high over sand bars covered with weed more than ever before. Awesome! Ive found they do spin out sometimes but you just need to change your pressure on the back foot from the heals more to the toes over the fin, into and off the breeze. Just need to have a few runs to work out your fin size.

Thanks Mick, Great info. Sorry to bloat out your session with my questions Marauders!

I am light (70kgs), and isonic 97 at 63cm wide. Probably most likely setup would be 6.7 NP RS Slalom in about 25 knots wind? I have got the iSonic to 33 knots board speedat Kyeemah, and have done 34 knots years ago at Canton on my old JP FSW 92 with a 30 weedy. Hoping to get to 35 knots with this setup, hopefully more?

I have emailed MUF. They suggested a Delta slalom 19-20 for me. I was leaning towards the 20, as the iSonic has a wide tail, but from what you say above, maybe 19 as a better choice? They have quoted me $190+$27 shipping. Is that the best place to buy, or are there other alternatives locally?
