I'm not expert but after some well know RIB makers asked for double price for ALU boats (like RIBCRAFT) I decide to buy ALU. I did drop email to RIBCRAFT but they use ALU for bigger boats only. I did buy mine in 2014 after Southampton boat show (thanks for this forum and pictures made by RIB.net users on this forum). On these days it was really good price for them. I have imported it from UK importer (now there is new one but the same person). Here you have prices in UK (not sure if they are still valid)

Deluxe

You can read that they are descent of some Australian RIB's but I did not check this history (it can be true or marketing). It is good for my needs
- I do like simple design and "work" look
- with 115 HO Evinrude my cruise speed is 45 - 49 km/h (3800 RPM - 4000 RPM)
- petrol consumption in this RPM range (Steel Rebel 19" prop) 2km per 1liter
- max speed is about 69 km/h
- it can carry my family (5 people)
- I tow it every year to Greece/Croatia

I'm not qualified person to valuate this RIB.
It is my first RIB in my life even I'm old (almost 50).
She behave really good in Greece (always wind and some waves) I can go 40-45 km/hr of course depending on waves size.

If I own it 10 y I can say go and buy.
But mine has only 2 seasons (2x2months in Greece/Croatia) and company has only 5 y.

Attaching 2 types of transoms
One chinese, other for a well known chinese mark found in europe..
How would you describe both transoms? Study case

Here is a photograph of the transom of the RIB that I have just disposed of because of flooding problems. One of five problem areas was that there was very little freeboard at the transom.

You can't judge a hull just on the deadrise at the transom, you have to look at the whole design from stem to stern. Many modern hulls flat off towards the stern to improve fuel economy & reduce the required HP for acceptable performance. Even then, there will be a trade off in sea keeping ability. Personally I prefer a full deep v for the full length of the keel & I'm prepared to swallow the extra fuel & HP needed.

You should have cheap tickets to UK. I do suggest to arrange some tests on the water a few RIB types.

It be better than academic "case study".
Even I'm academic phd I do prefer practice and real test.
There is also personal taste and personal preferences.

RIBCRAFT - very solid boats - search for "small boats big seas" on YT
And there is movie "how to make RIB"

You have leisure boats like RIBEYE and well know ZODIAC PRO OPEN 550.
You can call HENDY marine and ask also if they have any DEMO boat

If price be the only one factor ... not sure if any advice can help.
I saw on my eyes 2 small boats looks very similar, one performed well, other not (use the same engine). So even look is not enough I think

Flooding? How? Once stopping agressivsly not gradually?

What do you mean little freeboard? For what?
Thanks

Seen there 660. There is some difference.
By the way, any feedback regarding aluminum repair if needed? Heared is a bit problematic on welding due to strech pressure that can affect hull balance...

Stranger to me is seeing many aluminim hulls in china but much less in european factories or could i be wrong? Could china be leading here? !

They are. In Poland many new boats from ALU in 2016.
There is NORDKAPP shipyard in Poland (Norw. boats) and they start to make ALU hulls. XO boats also (made in Poland). Unfortunately no ALU hull RIB boats makers in Poland, a few in UK. RIBCRAFT threats them as more expensive:
