So does that mean the newer board will feel slightly more stable when not planning as the volume is around the foot straps ?

Marginally so, mostly they seem easier at the upper wind limit for their volume.

What about a modern RRD FSW with single and thruster V4 is a peach of a board. Simmer helix is mega fast and has a huge sail range, and I only really sail in bump and jump conditions.

I should mention that I was given a beaten up (but still ok) simmer quantum mechanics 75L quad that I've never used !

It seems to me that you currently have everything you need. At your weight surely the two boards should be plenty. The fact is the three-fin boards are draggier and you won't get the speed you want out of them, nor the acceleration out of the gybe. They are all about handling not blasting. Keep your single fin FSW for flatter days and try the wave board out in the wilder stuff. And if your FSW bites the dust then cast around for a similar replacement. Something from Patrik perhaps. You've already got it made. Take the focus off boards and look instead at building your skills.

Contemporary multi fin boards offer options old school shapes can't..

The idea is you change fins for the conditions.

The newer more compact shapes provides the benefits of a wider tail. Earlier planing, more power out of gybes, extra stability. Plus you get the benefits of shorter design. less swing weight, more control in the air. Add the extra fins for grip when it gets hectic or when hitting small surf or the tail width gets lifty.

at 67kg you only really need one multi fin contemporary board to cover most conditions. As an example, My son is 68kg, rides an 81lt multi fin wave board. Single fin when blasting in flat water or light wind, thruster setup for bump and jump and quad when nuking or small surf. He also has a 2008 jp fsw, 240 approx in length, 85lt volume. Is an awesome board which he learned on so lots of memories. He retired it when the 81lt turned up. He preferred the balance of the shorter board when jumping but said he missed the speed of the jp board (which has a flatter rocker) for blasting. So I put a single fin in the multi fin board to get him back the speed he was missing and he's happy with that for blasting. Even though the wave board has less volume then the jp fsw the wave board is more stable.

Well a really good condition used dyno popped up for sale so I guess I'm going to find out the differences myself now.
Also I picked up a Goya skinny carbon boom as I've been told this definitely makes a difference.
Amazing how much shorter it actually is next to my rrd, also the fin box placement is much further forwards in the dyno with the side fins in front of the back foot. Having the one tool do everything is really handy! I did notice it felt a little heavier than the rrd but it weighed 7.4kgs with the straps and 3 fins and the rrd was 7.1 without a fin so nothing in it really. The other thing I noticed straight away is how easily the paint work marks / scratches.
Wind tomorrow so hopefully enough to test it out.
There's been great reply's from everyone and have really enjoyed reading them , a wealth of knowledge !
I will update my thoughts and sure to have some fin questions.
Looking over it again as you do with new toys , can't believe the difference in nose rocker there was a lot of the rrd board that never touches the water !

Congratulations on the new board, I am very curious how you are going to rate this board against the RRD.

Normally when I buy a new board, there is no wind for weeks and you get wind tomorrow! Lucky you!!

And the boom? Great boom.

There it is! The glorious RRD 85. I had the exact same. The Dyno will have more uptake I think.

BTW: one of the main reasons I changed the RRD after 11 years of pummeling it in the San Francisco Bay Area is because a friend of mine had the same vintage and it literally split in two around its 10 years anniversary. I thought it was time to stop testing the resilience of my own board!

(Not meant as a critique of RRD. The board got hundreds of days in 5.5-4.0 conditions, and was still perfectly fine when I sold it for $200).

I will never part with the RRD I bought the 105 same year/ version just after I learnt the basics on a large beginner board then shortly followed up with the 85l. The 85l soon pretty much became my mostly used board and it's been all over the place , first planning gybes , first jumps etc. Thinking about it I paid around ?300 and it's had around 13years use from me with no major damage !

I've had a couple of goes on the new dyno now and overall very happy.The first session I was slightly under powered on a 5.2 so only got about 20mins before I put a bigger board on.I felt it jump well compared to my older board almost like I could spring off the ramps better and definitely more compact in the air.
Second session was more blasting in flat / choppy water with the odd small chop hop,I was well powered on a 4.7 The board definitely feels more playful , didn't notice that it planned much earlier but what I did notice is that it felt like it could plan at lower speeds.I'm sure in some of the lulls my older board would have dropped off the plan but the dyno planned slower/ easier to the next gust.
Whilst out I did think it felt slightly slower but when I check the stats on my Apple Watch I was up 1knt all round compared to recent sessions on my old board , maybe being a more comfortable ride makes it feel slightly slower.?I definitely felt more control when maxed out in gust.Really looking forwards to getting out in some decent bump and jump, feeling like that where it belongs and will notice more benefits over the old board.

Sounds like a great outcome!

What fins have you tried

Also forgot to mention another plus I felt was going up wind seemed easier maybe that's the tri fin set up that does that. ?

I just had the stock 21 centre and 12.5 sides , I will be looking for a good single fin option and a smaller tri set up for windy conditions.
looks like I'll be getting some solid winds to test end of this week. ??

Just make sure the single is not too raked like a wave fin, as there isnt much tail behind the box
Dyno can misbehave with raked single

Thanks I noticed a massive improvement when I used a more upright free ride fin in my older board as opposed to those small wave fins I used for years , so much it really has help my sailing.
