I will fish from my bass boat, 19-foot with 150 hp engine. If it were new, it would cost about $40,000. I bought it used six years ago, for $10,000.; it's a '99 model. Everything works great, so no need to update. Just like arrangers!
New boats might have more sophisticated fish finders, get a little better gas mileage, and be a trifle shinier. They might go a little faster, but 50 mph is fast enough for me and I seldom go that fast. To me a new boat is not worth the money and won't catch more fish! And all those areas can be addressed, much like arrangers.
