That's definatly been my experience as well..

I'm sure that just use "infusion/sandwich/kevlar" not guarantee best results.
But use them in proper way can give us light / stiff / good hull i suppose.

My question is: if RIB is ultralight it probably has problems with bow jumping on each impact (this is only guess).

Is the good solution to make ultralight boat with very deep V especially at bow ? For example Greek Skipper has degree at transom 33 and > 57 degree at bow (or something like that).

And/or moving console a little to bow ??

On the end such boat require some test to check I suppose.

I'm really curious if ultralight RIB like 7m long can have good ride on waves.

Why not to merge good fuel consumption (ultralight) PLUS good nautical properties on choppy Sea together ??

is it impossible or just simpler is make heavy boats good for waves ?

Yes, but at a sacrifice of top speed and width. The hull will have to cut in to the water like a knife as it "lands" off a wave. The planing pad will have to be very minimal. If the planing pad or the hull are too wide, it will be too buoyant, which will cause it to stop abruptly as it lands, causing "pounding".

It is generally easier just to make the boat heavy.

Of course to make a "TOP" RIB..this has to be coupled with a sound (preferably) tried and tested Hull/Boat DESIGN ..which in turn is then also well made/manufactured to the highest standards.

After that ...All that's left is for the owner to do is decide on Power...(engine size/ type) .....Rig...Layout ..and equip it to do exactly the Job HE/SHE wants/needs it to do..
....then learn to Drive it properly

My advice would be to Tryout some RIBs of the type and design you're thinking of buying,in real conditions!....don't just buy what you "think" MAY work for you...why would anyone take the chance??
..though plenty have..and do!

My thoughts. Will try to rent Skipper-bsk 70 in Greece and test it within 1-2 days. There is every day wind on evenings in Greece (4-5BF) so test it on the waves be very easy...

Personally, I prefer a heavier boat with corresponding power. In flat calm conditions (1 day per year if we're lucky ) a light boat would probably be faster in a straight line. In any kind of sea however, I think a heavy well powered rig would handle better & outrun a lighter equivalent. In the rough, you can drive a heavier boat harder & it will be kinder to the crew.
All IMO naturally

well said. this is what I keep saying and our Baltic hull is just that and in the rough with lots of power just goes faster

Bigger, heavier, well powered - I understand that good shape/hull also.

But for example Higfield Patrol 640 require trailer 1800 kg
And RIB-X confirmed that XP680 full setup with trailer be below 1300 kg

Both with 150 HP on the back ...

I know that RIB-X is new kid in the block but made in UK.
On the end I have to go to UK and test a few I suppose.
I hope it be not problem to have some waves here

Matt are you sure you want to test a rib in the UK waters. Won't it be a bit too cold for you

I do expect:

- warm welcome
- hot adrenaline when drive boat
- a glass of "famous grouse" after trip or similar good item
- a trip to RIB X factory - it be hot to see a few boats in progress

I do have even Musto trauzers and jacket - newer wear them still with tags
