I'm in a bit of an opposite position.  My wife and I own a nicely equipped 21' welded aluminum boat.  We use it a lot, all over the NW.  Rivers, lakes, bays, fishing, crabbing, etc.  I'm not going to lie, below freezing temps winter steelhead fishing and such it's nice to have the heater going in the covered part of the boat to get warm, and out of the weather.  That being said, I'm getting ready to buy a couple of Hobie Outback kayak's.  Won't be selling the boat, but looking forward to some different type of fishing adventures with the kayaks.

I grew up and spent 33 years in Alaska. In addition to other boats, I had several kayak's up there.  There is a lot to be said for the allure of being human powered, simple, and very quiet.  There are areas where we enjoy fishing in Florida and Texas where you need to use a poling skiff or a kayak to get to some great areas.

If I had a limited budget and had to make a choice, I would go kayak without question.  I don't like unreliable boats.  With power you can easily get further away from the ramp, and break downs can be a real hassle, and potentially unsafe.  I personally would much rather rely upon my own physical ability to get me back to the rig than an inexpensive used boat.  No motor to flush after using in the salt, or dirty water. Rinse it off and call it good. Don't need a tow rig.   Simplicity has it's own kind of beauty.

I have both----different horses for different courses.  14ft Livingston with 20hp Honda for fishing  with a companion, or running a few miles, and Hobie Revo 13 for lakes and the Strait (Freshwater Bay).  You can never have too many boats!!  I looked at the Hobie PA, but you really need a trailer, that thing is nice, but HEAVY!!  Newer Outback nice too, but I love my Revo---best combination of speed, stability and roominess.  I used to (in the 1980's and 1990's, see my gallery) fish in a sea kayak (17 ft Northwest Cadence) for multi-week expeditions to various  Sounds on west coast Vanc. Island, but at 76, the Hobie suits me better, and my expedition days are over.

At 76 you are out fishing from a kayak!  Huge respect for you, and I hope you enjoy many more years of fishing.
