SR 5.4 navy spec Jockey seat, height modification?

[C-NUMB]

The Jockey seat on my RIB is kind of low, guess it much lower than most of traditional jockey seat. Considering lifting it...

- anyone done this, any good ideas how to(without making a huge project of it)? Was considering creating a C beam of GRP, but that start's to sound like project

- how much, i am abt 180 cm , don't have any rib's around to compare, maybe 10-15 cm?

In the long run planning to make a totally new, but don't have time before this summer.

I am sure matth did something to raise an sr5.4 some time ago. Maybe using some 4*2, but cannot remember details

You are right, there was some discussion about possible using threaded rod(?) to lift the seat or something like that...Can't find it though. Think lifting it would be easier on the back.

a 4*2 sounds about right, its about 10cm

I am also considering to renew the foam, it has had a hard life, not much cushion left.
Guess the solid stuff is more suitable, any specific material that should have preference?
Shock mitigation foam would be nice, but guess it would cost a fortune, hard to source also.

If the foam is shot replacing that will lift you up a fair bit.
Reconstituted (chip ) foam seems to be the preferred stuff. There are different grades of firmness often described by weight. Eg 5lb 6lb 8lb 10lb. I used 10lb but it was way too hard so would think 6lb would be ok.
