They need to be set firm enough that the suspension doesn't compress for normal sitting weight nor does it move for smallish waves.

There is no sensation of bouncing wildly up and down. The boat comes up and you stay put, the boat falls and you stay put so the occupant's ride is more level than the boat's ride. There is much less movement relative to the controls than you get on jockey seats where you are located only by your knees. I do feel though that a harness is a very worthwhile addition to the seat to restrain your torso from fore and aft movement. The sort of movement where, when standing at a jockey seat, you might risk coming into contact with the boat's structure.

If the energy can be effectively absorbed with the minimum of vertical travel, then so much the better.
My choosing to fit suspension seats was driven by the same reasons as Martin has for his enquiry, namely, I wanted to continue boating. In a well supported sitting position the load is distributed over a reasonable area of your lower body and your back is held in a good position for carrying the loading from the upper part of your body. To minimise the load on your spine, the load per unit of time needs to be as low as possible and this is achieved by having a long travel suspension with a correctly rated progressive spring system which will not bottom out.

Quote:
Bucket seats with suspension may seem to be a good idea, but if they work well then you will tend to use the boat harder, because it's fun. At the point where you come off a wave just that bit harder than the suspension can handle, a damaged back is going to become very vulnerable.
Well that's up to you as a driver. On a leisure boat, a good driver won't create that situation.

Long travel suspension is important in cars and bikes that go over rough terrain because they need to keep the wheels in contact with the ground.
Maybe aye, maybe no. At high speed over rough ground which tends to be potholes, a vehicle ride will be much smoother if the wheels don't follow the ground. If the roughness tends to be bumps, it may be different.
At 60mph, the track up to my house is nice and smooth.

Assuming your wife is generally fit, then the most practical answer would probably be to fit jockey seats and for your wife to stand up rather than sit at all. If that's not an acceptable option, then I'd suggest the Ullman seats (actually I'd probably suggest seriously considering whether a RIB was actually a good idea).


If his wife is fit i will come out on every trip and she could sit on my lap my arse is quite well padded and should offer some shock relief

Yes, but the major forces that the seats are going to have to deal with are downward. In my experience at least, being thrown upwards out of your seat is rather less common than crashing down into it!

My the way John, I thought I'd tell you. Martin hasn't got a RIB, it's a largish Cruiser. I think the Ideal solution for Martin would be to try the tractor seat bases that Clice can supply. At 60 it's a cheap enough gamble. I for one would be interested if it works.
Ah. I thought the had a Shakespeare RIB. I'll get Biggles onto the case and have him evicted!

I wasn't actually thinking of your type of seats (and I was referring to fast boats! ).

As you mentioned, the damping is critical too. I've driven one particular RIB with seats that were more like a fairground ride!

There sometimes seems to be the perception that longer suspension travel is always better though, and it's not as simple as that. Out of interest, what's the maximum travel on your seats' suspension?

Sure, but even good drivers get it wrong occasionally. If the consequences are likely to be severe (and we don't know if that's the case or not in this instance), then it may be a risk that's not worth taking.

Don't get me wrong, I'm not arguing against suspension seats, and I'm not saying that they won't be the right answer for Martin and his wife. However, just fitting a pair of truck seats might not be the best solution.

I would have thought they would have been quite appropriate in a Traktr Cab!

Didn't Alan Priddy fit truck seats into Spirit/Jolly Sailor ?

As I am getting older I have been thinking about Suspension seats and have decided they would be perfect if I had Piles of money!

As far as I remember, Spirit of Cardiff had regular car seats (from a Citroen I think).

If you had piles of money then sitting on a rubber ring would probably be the ideal solution.

now that reminds me of a story of a famous rib builders wife running down the pontoon at the SBS with his pile cushion. Shouting to him that he'd forgoten it.

I am sure Alan told me the were truck seats, is he around to confirm?
