People are installing carbon monoxide alarms on the transom and the levels are high when surfing and no wake speeds. Definitely as a boat captain with my family on board not something I’m going to risk with friends and family. Swim platform and seats are for chilling in the swim coves now when the boat is not running.
Our Pleasure!!
I can't say if it's accurate, but I've been told that carbon monoxide poisoning at the transom is only a risk at no-wake speeds. While surfing, there is generally plenty of airflow. But I'd rather be safe than sorry, so will definitely look into a carbon monoxide alarm. Let me know if you have any alarm recommendations!
Wake 9 did an awesome video covering this with tests.
Great pics! Did you have any external ballast?
Agree. Thanks for pointing me to it!
I do, I have the 19' Yamaha ballast kit. But I don't use it often. Mainly just stock.
Man thats a big wake in the first picture for just stock ballast. mine isnt near that.
That picture was with only three people on board (2 kids, 1 adult), everyone on the starboard side, with full rear ballast, 75% front and 10 mph.
thanks ill try that combo. the best ive got was 100 on surf side 50 on non surf side and 100 in front.
Always go 100% rear, don't try and list the boat with ballast. It surf's better with 100% rear and driving straight.
so you just list it a little with a few people then i take it?
What you have been told is not very accurate. At surfing speeds you will get backflow pools and the CO can and does pool on the platform. I put 2 CO detectors on my boat. One on the platform and one just above cockpit drain on the back wall. I have experimented at all different speeds. I have had them both go off. It depends on speed and wind direction as well as what is in the cockpit creating different vortexes and pockets. Not safe at any speed to be on the back platform, imho.
This might be true with stock ballast but the addition of the 25ft transom bag and listing the boat have had some outstanding surf waves....
Positioning the people is more to not counter the ballast on the side of the rider. You don't want to list to the non surf side.
True. I have two additional external bags, and have seen the best results with one bag on the surf side vs a bag on each side.
That's what you use on the transom of your 242X or a 255X?
