Hi Jeff, I'm also motivated by my old / dodgy bones.
I'm working on a wee project just now with my air floor sib.
As you know I took my Ali floor 3.5m Honwave to the Oban outing this year.

I much prefer the softer ride of my 3.8m air floor Honwave as it is a bit more forgiving on my neck / shoulder injury in a chop.

Ended up taking the Ali floor though purely as it had the fixed VHF and auxiliary engine .

As both Sibs use the same sized seat I've modified the seat to be interchangeable between the 2 Sibs.

I've mounted the VHF set and aerial, fish finder, chart plotter, battery, charging points and volt meter to the seat.

Just working on a mount for carrying my wee 2.5hp auxiliary on.

I was also inspired by your antenna attachment and ensuite facilities

I wouldn't be without my ensuite now

that all sits nice on the seat there i did wonder about doing that myself but i might be a bit clumsy and stick my feet through it we are showing our age a bit re ensuite but if you're gonna go then it has to be right
to be honest i was impressed with the aretec of al's the way it took the rough stuff i guess the honwave will be similar also that 300 mm more makes a difference.

Yup there's no doubt the ensuite is the way forward. Wouldn't set afloat without it now.
I was rather sore after the lumpy crossing from Lismore Lighthouse to Ganavan.
I had intended going back out but the crossing knocked the wind out of my sails so I was happy to call it a day .
I might have been a bit fresher in the airfloor?????
I think the air floor does definitely help in some seas as there is a bit of give in it and the floor kinda acts like a shock absorber.
The extra 300mm also helps as it pretty much 1ft longer and it does help bridge the gap between some wave crests better, some of these waves would see the 3.5m plough into the troughs.

final update

on a recent trip round mull with a 10 1/4 x 10 prop carrying 70 ltrs of fuel & camping kit i guess weight wise two men up conditions calm achieved 20 knots at 5560 rpm so i guess speed wise about the same as the 11 inch prop but from a response perspective a much crisper and quicker result in the chop and rough being able to stay on the plane for much longer up and down significant waves which is what i wanted fuel consumption for the 138 km was around 30 lt average speed 10-11 knots

Good result Jeff. That's exactly where you need the outboard to perform when working a difficult sea. So much more important than theoretical high speeds that are mostly impossible to maintain if you take your SIB to sea.

We expearianced some difficult wave formations on the south side of Iona that's when it came into its own David as you say maintaining the plane more important than speed so should be sorted for all conditions with the three props

Iíve always tended towards the underpropped end of things for the very same reasons. Iím more than happy to sacrifice a few knots of top end, in exchange for lower down grunt & throttle response. The times you can run flat out are few & far between.

new sib seat

after trying this before on the bench seat not very successfully i thought i would make a base plate so i could set the strapps where they work and support. on the mull trip i could have done with a backrest which prompted me to fix a seat on to the bench seat it will have a single bolt through the seat base and bench which allows it to swivel slightly for best position.
the seat is a canoe seat and the base is 25mm HDPE cost about £70 all up.
a few pics to show it

seat up date

using the seat on the recent skye trip proved to be a worthwhile addition for me especially for the long days afloat it was never intended for on the plane just for displacement speeds and sightseeing which was spectacular even better with back support.
one problem that occured was the front straps pull down at 45 degrees which tends to pull the backrest down and allows it to go too far back, i had a large HDPE bach support hinged at the bottom to help the backrest but it proved not to stop the backrest sliding down a quick fix was to weld a web on the back preventing the HDPE support from going further back than i need it to be it still all folds down and can be removed with one bolt and two straps off the hogging rail.
