What would take to flip a rib

[Nyarla]

It`s combining the throttle and steering to give max control thats difficult.
You want both hands on the wheel and one hand on the throttle at the sametime for efficent control, eg bike style. I don`t count foot control since that is not really responsive enough. Feet are ok for gear changes but are very poor for throttle control.
Bike style bars would be too heavy for cable steering in the limited lock bars give you.

Getting back on topic...how hard is it compared to a hard sided boat of the equal size to flip a RIB?

Without reading through the entire post to check if someone has already mentioned this (apologies if so) but the windage (and thus the leverage) from the tubes is enormous in a goodly blow. So, to answer your question, IMHO, in certain circumstances, a RIB will (can) flip earlier.

It is suprisingly easy to roll a rib if you end up beam on to a rough sea, I rolled a little Ribcraft, while performing a dinghy rescue.

Bloody Hell!

Quicktime is ok as long as you download media player classic - will play almost anything including that RM rubbish....

Have seen that video before and it sparked quite a bit of debate - I still say most RIBs have their weight too far aft.....

Hm....so an inexpierenced driver can essentially flip a RIB real easy then?

The way I see it, its like driving an SUV. Sure you can flip an SUV but only those that have no understanding of physics and a little understanding of what their handling, anything is possible. I think also knowing your limits and/or understanding the conditions you are in require the proper action. I certainly wouldn't take my SUV going 60 mph around a square corner full speed. I wouldn't expect someone to go flying into the crest of a steep wave expecting zero consequences coming out the back! Of course the dynamics of a churning ocean is more complex but the same ideas apply.

Couldn't agree more - quite a few years ago there was a spate of accidents involving the little Suzuki SJ410 rolling over(missed that one Gavin) - quite a few people were killed - mainly teenagers who bought one as a cool beach car - they couldn't quite grasp that something with such a short wheelbase and a high centre of gravity would be unstable!!!

Makes it great offroad though!!!

Hey guys, totally understand how the back flip or roll in turn could easily happen. But on my first run out in the sea in a bit of a chop every now and then when I came off the top of a rogue wave the boat would list over to the right hand side. I’m guessing mainly because of my weight added to the battery and probably the under deck fuel tank. I also noticed as I came sideways along the waves as I went over a wave it would sometimes do it and other times list the other way depending on the angle we came off and hit the next wave. I’m just wondering if your going straight and going pretty quickly if it is possible to fully roll a rib if you hit a wave at the wrong angle?

Aye, you could flip it. Store anchor and chain as far forward as possible, and push crew forward. Also don't take a nasty head sea straight on. Read the waves, go at an angle, zigzag, duck and dive and ease off the throttle when you look like your going to fly. It's great fun.

Holy thread resurrection Batman!


Broad side on the right (wrong) wave will flip a rib, never be broad side in the break zone always bow into the surf, also a flowing sea can flip you so stay behind the crest of the wave. The huge bouyancy of the tubes keep ribs afloat, it takes a lot of force to lift one tube over the other (roll the boat) but a wave at 30 degrees has a massive head start.

Stuffing the bow in a following sea can also cause a roll as the stern raises it will go ove to one side and then roll and very little you can do once you have stuffed it


Most boats are far more capable than their operators there are some exceptions
