How much does a rib weigh - roughly?

Hi, can anyone tell me roughly how much a 6m rib with a 90 4stroke on it would weigh?

Thanks

Fletch

its going to be hugely variable depending on brand, amount of kit, fuel etc on board.

As a starter though Humber quote their boats (this is no kit, no engine) as:

6m Ocean Pro = 495 kg
6m Destroyer = 415 kg
5.9m assault = 325 kg


Ribeye claim a 6m rigged with engine etc weight 890 kg

Ribcraft claim their 585 (they don;t list a 6m) weighs 588 kg + engine.

Depends what boat but i reckon 500kg for the boat (bare) and about 150kg for a 4T motor of that size, won't be far off but don't forget fuel and accessories

As said every boat is different but i'd work on the basis that the 6m boat fully rigged will be around 3/4 tonne before you add fuel and carry removable kit.

If your hoping to beat the 750kg towing limit your unlikely to manage once you add a trailer.

However i used to have a leeway 6.3 that was well under this weight, I also had a Halmatic that was well over.

Thanks for that, it only needs to be rough, it is for me engineering the rails to build a track and dolly to launch and recover the rib, so i will work to 1,000 Kg.

All the best

I have pulled 5/6m ribs out of the water that weigh what felt like 1300kg, when they have a hidden floor full of water due to failed electric pump...
Boat would not plane, so knew some thing wa wrong.... removed the rear bung when out of water and 50 gallons of water comes out... Just one thing to allow for....
