Will a C30 or R31 sport top self right if knocked over by a wave or something? Or will it stay upside down?
 
We have been in some very rough water (6+ ft waves, though not by choice) in our R-31CB and it has not yet come close to giving us the opportunity to experiment with that and find out.
 
A lot of questions rolled up in there.

Has one ever sunk? The wisdom of the board is one, once, when it broke from a mooring and was dashed upon rocks.

Can it be rolled? I suppose, if you really tried hard to make it happen. Put yourself into large breaking waves on the beam like surfing waves in Hawaii and I'd bet yes. Don't do that.

It is designed to be a coastal cruiser, not a blue water passage maker.

Keep waves on the nose. Avoid following seas, but if you must don't let following seas put you into a position of surfing down the side one where the bow will plow then the wave will push the stern around to bring you beam to the wave.

And never run beam to large seas.

Keep doors and hatches tightly shut when things get interesting.

Don't do anything dumb. Read up on what are the ways to do that something dumb.

I looked into a related question, which was if you took water in the cockpit from over the stern, how long would it take to clear. Its a complicated question but I satisfied myself.
 
I'm guessing the inboard diesels would have no trouble self-righting, with that heavy engine way low below the water line. I'd worry about the outboard versions though, where the weight is moved from below the waterline to way above it.
 
My opinion would be no they are not designed as a self righting boat. Rangers and Cutwaters are coastal and inland cruisers. There are many threads describing the sea handling characteristics but none would be self-righting. There was a new Cutwater 30 (outboard) that had issues, took on water at the boat owners dock do to what was described as 1' to 2' waves. He posted pictures of the boat floating capsized. It did not self-right.

If your replacing your Lagoon 400 for a 31 Ranger or 30' Cutwater and expect the same sea handling and ocean rating CE it is not in the same league. Rangers and Cutwaters handle well but you must know their limitations. Mine are 1' to 2' are enjoyable , 3' to 4' are tolerable, 4' to 6' are not fun and anything larger I made a mistake I should not be out here.
 
We had some very large waves aft quarter on our 31. Cabinets popped open, Admiral very up set, boat took it all. Was really glad when we got to sheltered water. Believe Rangers can take more than crew!

That is a good point, it rolled and sank. However, it was probably filled with water to begin with. If it had just had a beam wave that rolled it with closed doors and hatches, wonder if it might have self righted.
 
I've posted this before, so forgive the repetition. I tow my Rib Avon Rover 3.10 throughout most of the Bahamas and across the Gulf Stream and have found that it acts as a sea drogue, keeping my stern square to the waves which keeps the bow from rounding up on the side of the waves. Not towing the dinghy I find it very taxing to apply power and rudder when a rogue wave starts to spin the stern and bow digs in as the boat rounds up. The Gulf Stream is very beguiling and has different moods as you start to cross to come back to Florida. Ranger is a good boat, but a good operator makes it a great boat. I too try to avoid the 4'-6'; short intervals, of course, I sometimes confuse the way NOAA measures the wave and the way I measure them with a cold brew or stiff drink :lol: :shock: 😎
 
THANK YOU for that reminder on technique.

I had forgotten your tip.
