Is there are a general rule for choosing the most appropriate size of board for allround flat water freeride sailing. For example volume should be equall to body weight or volume should be about 10 litres more than body weight etc.
I hope this question makes sense?

depends on the wind strength.

rough estimate...

light wind: 10-18kts... bodyweight in Litres + 40-50L. For my 70kg+, I have a 110L board, thou 120L would probably be better (7m sail, considering getting a 8.5 as well).

medium wind: 15-20kts bodyweight in Litres + 15-25L. For me, 90L board (5.9 + 5.3 sails).

high wind: 20kts+ approximately bodyweight in Litres. 75L board for me (5.3, considering getting a 4.7 as well).

So depends on what the typical wind range is. Also, light wind board will work good for light or medium winds (might work in high winds too, but won't be very nice to use unless you have really flat water)... medium wind board will probably work for medium and high winds. Doesn't really apply the other way around.

Hope this helps :).

I would say thou, if its your only board.. go the medium wind combo, for my first 2 years sailing I had a 96L board + 5.9 sail, and I rarely missed out on any sailing days.

Thanks for the tips. I'm trying to clear out space in the garage. I have a 93L and a 103L so I am trying to work out if I really need both or are they a bit of doubling up. By the way I weigh 80kg.

Maybe I should also mention that my sail sizes are 5.2, 5.9, and 6.9 and as I previously mentioned I'm about 80kg and mainly doing flatwater sailing around the swan river.

I'm trying to work out if I really need the six boards I have in the garage.

The answer is also a little dependent on the types of boards you have. I have a 90L slalom board that's an early planer, using a 7.8m I can start planing in gusts of up to 14knots and keep it going in 12.

The two sizes you have are pretty close together. If you find you have more days in overpowered sailing replace the smaller one with less volume. Or replace the bigger one with more volume if your slogging too much.

Or just park your car in the street and get a few more boards.

I KNOW I don't need all nine boards in my garage..

Maybe I need a smaller garage?

It also pays to remember that volume isn't the only consideration. It's only really relevant when you're wondering whether you'll float or not.

Width and shape are what we really need to compare when figuring out whether a board is suitable for the job in mind. Volume is a poor indicator.

As an example, I have a 220 litre bic Melody (old plastic longboard) and a 230 litre starboard Start. There's only 10 litres difference between them, but they are COMPLETELY different shapes, and have entirely different specialties.

You'll float on either board, so if you really have to choose then it comes down to the most common conditions and which board is most suitable most of the time.

Or, as has been suggested, just keep all of them (guilty!!) and get a new one as well.

Maybe it's easier to just figure out a better way to store them in order to make better use of the space in the garage!

The 2 boards in question are a 266 mistral flow at 93l and a 277 F2 Ride at 103l. At this stage I was thinking of keeping the mistral and selling the F2 depending on peoples suggestions. I need a new paddle for my paddle board so looking at freeing up some cash without selling a kidney or one of the kids.

If you were in Bris I'd say keep the Ride but the Flow should get plenty of work in Freeo. Don't you find that more fun?

I've thought about this alot since I am about 100kg so my weight does have a big impact. My conclusion now after going through having multiple boards and sails for everything is that volume isn't really that big of a factor, as was said previously board shape is fairly critical. Now, I only ever ride an 85l board with a 4.5, 5.3 or 5.8. Then again I never go out if its less than 20 knots. For me I am running weight minus 15 litres, which for the average 80kg guy would suggest a 65litre board. If people are planing on 5.5 to 6.0 I am also planing on my 5.8. Volume is 100% of the float equation if you are not moving but once you start moving the push of the water against the board has more of an influence on wether you are sinking or floating. The faster you go the higher you float until you are planing. Once you are up and planing volume is irrelevant and frankly I am always happier on a smaller board than a bigger once up and running. I do sometimes have to wait for a bigger gust to get up and go but once up which is at least 80% of the time in 20k+ I am way happier than when I used to run bigger boards. I'd rather trade off a bit more of a wait to plane for a better planing experience than the other way around. So, I'd go the smaller board.

Where I sail, early planing characteristics are the most critical; you have to suck it up and hold down oversized gear when it gusts, otherwise you don't spend much time planing.

Have you ever sailed your Ride with the 6.2 and the Flow with the 5.2? If one board can't handle all your sails, decide which end you sail the most (or maybe which you enjoy the most) and keep the board that uses that, and accept you're going to lose some range.

I have a huge soft spot for my Flow*, but I don't ride it much these days. Thin profile seems it don't get going unless well powered up compared to todays modern shapes (shorter and stumpier). But when the Flow is up and going, it's simply a fun board to ride. It gybes so effortlessly and tight.

*Actually, I think my Flow has a hugh soft spot too from my poor patch up job...

I mainly use the flow with my 5.2 and my 5.8. I also have a 6.9 but I haven't used this sail with the flow only the ride. If the wind is that marginal I'm probably going to indulge in my new passion and get the sup out instead!
