Transom extension / pod?

I am wondering if added a transom extension/pod would be worth doing to my Hurricane 440?

I would like to:

- gain deck space
- have internal fuel storage inside the pod (again more deck space)
- improve the handling of the RIB in choppy short frequency wave conditions (longer hull)
- have room to mount a larger auxiliary motor next to the main motor

Are there any down sides to adding a transom extension/pod?

I've attached a photo from the site that shows a 440 with a pod.

Thanks.

You mean other than a big lump of weight hanging further back than the tubes and so making it easier to cartwheel it ?

I think what you really need is a bigger boat. Everything you just described says "bigger boat"

Yes you can add a floating engine bracket. It would be really expensive relative to a boat that size if done correctly. Brackets are good for holding engines and not much else.

Near idea and the pod can also serve as a platform to get onto when entering the boat when diving.
I think this is a sensible option and consider the same for my boat.

Fuel in the pod? Then the pod would only provide negligible flotation (the difference in density between water and gasoline)

Upsides: Hull acts as if it's longer. Gain deckspace (but only the amount that the engine used to infringe on existing deckspace.)

I doubt you're going to be able to use the pod as a swim platform on your size boat (I've got a wide 18' RIB and can barely use mine that way.)

Downsides: If the boat is already tailheavy, it's going to become moreso due to the longer lever the motor has to work on. You likely won't be able to use the pod for fuel unless you install forced ventilation (at least in the US) to vent fuel vapors. You'll likely need all new control cables/hoses, and probably extensions for the engine wiring harness. You'll likely need to re-engineer any deck and bilge drains/pumps.

Doable? Probably. Worth it? Up to you, but I'd say it starts pretty well into the "probably not" range.

You may want to look at a jackplate or similar non-flotation (non-wetted) bracket. You won't gain flotation at the back or extend hull length, but you can probably get some deck space back. Still have a lot of the other issues mentioned above. Cheaper (most likely) as well.

RIBase
I would class it as an interesting experiment on someone else's rib. But would not do it to mine

Those single engine brackets look like they might be good.

Also Avon have used them at some stage?

Avon Inflatables Seariders

When stationary the tail heavy issue will be noticeable but at higher speeds less so as there is also lift developed by the propeller(this applies also to jack plates). Like jyasaki says, hull will act like longer.
