Can you roll a 19 Angler ?

Question:
Is it possible to roll a 19 C-Dory using your trim tabs, i.e. highspeed, play with the tabs, turn sharp, hit a wave, weight all on one side ... ?

Any boat can be rolled, the C-Dory with a low ballast point should pop back up rightside up so long as you keep your cabin door and windows closed. Let me know if this is not the case . . .

Good luck to you guys! Beer

Tom,

Having met both of those guys, I think they're serious. Shocked

I don't want to be IN the boat when you try it, but I'll be nearby to get the photo.

Given the right (wrong?) conditions, anything is possible. Not likely, though. Has anyone here ever heard of such an occurance? (Not one of those: "I knew a guy who knew a guy whose cousin once heard of guy that said..." Wink

)

I've been reading here for a couple years, Tom, and have not come across anyone rolling a CD (although the photo archives do show a CD nearly rolling in the surf in Mexico - and it came out fine).

These are amazingly tough boats; Wild Blue continues to impress me everyday.

Best wishes,
Jim B.

I don’t know if it is possible to roll a 19 but you can roll a 16 if you use the swim step.

My 22 rolled in the surf with the previous owners in it. Waves and the shore bottom helped the process along.

I think you would really have to work hard at rolling a C-Dory in open water with a mild chop. (impossible ?)

Five pounds of Wisconsin Cheddar says you can't roll your 19 in open water with rated power and no huge waves. I sure would like to watch you fellas try however. Beer

Dave - you better hope you can unroll an 18 footer!!

I got caught in a ship wake once off LA and the wake threw my 22 cruiser onto the starboard side. I was looking DOWN at green water thru the side window. The boat popped back upright immediately. That was way too close to 'rolling' for me!!

The lesson learned was to run away from a ships wake at 90 degrees and then gradually slow the boat and let the wake go under the boat from the stern.

I think that if you don't overpower the boat(ie: stay with the factory power recommendation), and don't go parallel to a steep wave train (ships wake) these boats won't roll over.

High powered, fast boats that have a straight side, (not curved like a C-Dory) can experience a condition called 'chine walk' where the boat bounces from one chine to the other. This condition can amplify until the boat is 'bow steering'. If this condition is allowed to continue, the boat can flip sideways. I have seen videos of hydroplane racing where a boat does just that.

Trim tabs can amplify the roll effect of going sideways across a wave (the up-wave tab down and the down-wave tab up).

If you use tabs, consider the tab position prior to changing the boats course in big waves. Going 'down wave' faster than the wave train is the most dangerous time for our boats. That is the time to have the tabs retracted and the weight in the boat shifted aft. The stern has a lot of buoyancy and will rise to a following sea. It's surfing down a wave and submarineing the bow at the bottom that can cause real problems.

Tom, Tom, and Dave, let me know if you want a 'stand by' photo boat for your rolling experiment. I have a good fly bridge to watch from!

I remember a discussion on this topic on the 'old' site, it was before I got my boat though, so was just mildly interested. The shape of the dory bottom with its very small skeg lends itself to sliding down a wave if caught sideways. I believe I've experienced this just for a moment or so while handling large waves from the side while going slowly. It can be quite alarming at first, but afterwards you realize it's not too bad of a safety factor! A deep vee will tend to trip on its hull and broach in those kinds of conditions. Of course, very large breaking waves can roll anything plus trim tabs could be a factor in tripping the stern. That's about all I remember from that discussion.

THe risk of rolling a boat while using trim tabs is highest with following seas. I've had a few instances where the boat suddenly took a hard turn, and nearly broached, or so it seemed . Scared the crap out of me. It really was all do to my inexperience with trim tabs. As I understand it, when you have swells/waves coming from behind you should have your tabs up. What was happening to me was the bow would grab hold and track like it's suppose to but the stern was being pushed sideways by the following seas. The boat righted itself with backing off the throttle. In reality I probably wasn't anywhere near broaching but it sure feels like it frmm inside the cabin. Live and learn.
