I have been doing some more reading and it looks like the majority would not go for any SIB longer than 4m without a trailer....is this your experience with the 470 and I guess even more deifficult with the 530? what would be a decent engine size for both 470 or 530? in 2 or 4 strokes which is still below 50kg?

I own and use an ex Royal Navy Gemini and ex Royal Navy CRRC 520.

They are not the same same as the Zodiac military series sib you have but are not dissimilar(over 4 metres)....so for what it is worth...
I use mine on trailers/launching trolley because they spend most of the year on them and 6 monthish in storage so are easy to break down.
If they are going to spend more than a few days afloat it is more practical to to carry it to the waters edge in a pick-up and assemble them there (20 minutes).
If you are only going to use it for a couple of hours/daily use periodically then a trailer of sorts is the way to go...believe me assembly/disassembly will soon take the fun out of it especially if you have dive/camping/hunting equipment as well.
And on that point a max of 25 hp two stroke outboard engine is quite sufficient for propulsion and manhandling to the waters edge. I recommend you do not leave it on the transom during transportation on the road.
A defunct caravan chassis is good to modify for permanent usage.

Hope that helps.

At the end of the day these boats are (530 Mk 4) just shy of 200Kg without a engine. Save your money and spine, get a trailer and tow it.

Many thanks, I instictively love the look and design but folowing the advice received will take it a bit more time to evaluate my needs before buying it. The issue with Panam is that there is a wide area which is worth exploring, pacific and caribbean side and sometime is may worth putting the equipment on some small ferry services to island further out 30/40nm...

If I have to trailer it, it may be perhaps worth investing on a bigger rib with redundant small o.b. to get me to some offshore islands 35/40nm out of Panama City... I have done 60nm on a 21' sailing trimaran but it was always within sight of the land... I am not sure if even a bigger FC530 properly set up with rigid floor and with a small redundant engine would be safe or practical for criossing 35nm of clear pacific with swells up to 8'...or not?

I am aware that there is not one size for all purposes and there will always be some compromises but I am trying to find out a bit more about the boundary for use of these SIBs...

Many thanks, I love the rigid floor and the transom strenghtening...how are you finding using them?

It works really well, it is a perfect boat for fishing, crabbing and throwing gear around on, I put down some heavy rubber matting as well so nothing would slide around.
It is really stable (obviously) and the ability to walk up and down without putting stress on the joins of a aluminium floor is really nice.

Thanks.

Mk4 Floor

This is a picture of my floor, it's Fibreglass over foam, essentially a big surfboard.

That fiberglass deck is the best idea for these sibs i have ever seen! I see from your pics that you have a keel in the deck as well! that is a great idea.
