But both of you are in modified V Jon Boats. What gives.
No matter what you've been told these principles apply to all type vessels. Jon boats have a naturally low righting arm and are not good choices for those that get seasick easily nor those likely to encounter waves. They're perfect for the average lakes you travel to though not for the bigger lakes like the Nock, Blue Marsh and Raystown...I'd not go near them. Jon boats are not inherently dangerous but rather the operators are. That is why I encourage you to read and read. My last boat was a Carolina Skiff 238 CRV, Flat bottom but with smallish sponsoons. The boat road terrible in bay chop and bobbed until everyone was sick. But once back inside everyone loved my boat. It held 14 people. Lots of initial stability. Great for calm bays, large rivers and medium sized lakes. Any boat you ever own will have safety parameters specific to it. Your job is to know them and anticipate their needs and not go where you shouldn't. At gouldsboro I constantly find aluminum scrapes all around stumps and the edges of rocks where people had used their boat in the wrong way. You see safety and performance apply to all vessels in different ways regardless of our stereotyping them. Buy according to your potential and conditions and you'll have many years of fun.
I've had a 29' Sailboat that had a 4' deep, 3100lb lead keel, 25' macgregor with a retrievable 800' Iron keel, 22'11" CrV, 17 foot Magregor sailboat, Three 17' canoes, 10' homebuilt skiff, 12' homebuilt drift boat, one 12' Kayak and a 14' Fiver. I read extensively all my life about boat design and I visit Mystic and St Michaels Museums Frequently. As an amateur I've gotten around.
The only dangerous boat is the one that a human put where and/or when it didn't belong there. I could feed you some more charts and lectures but if you 1) won't read them or 2) won't believe them or 3) won't apply the knowledge then I won't bother you with it. I just really feel that you would gain more from the rest of your life being on the water than to avoid it and miss out. We can't continue to perform like we did at 20. Every time you say you'll put it off until you can get a better boat then more years pass away. With age there are certain things that cease working on us and when you figure it out then you'll need even more boat. So you'll put it off again and the same thing will happen down the road.
Do what you want but I'd get out of the kayak world and into a real boat sooner than later.
