I'm thinking of trying a pontoon boat for the lower Sky and Snoqualmie rivers for salmon and steelhead. I have never tried one anywhere. Is this a good idea?

It looks like a fun and efficient way to fish but since I have never tried it I have many questions:

Are they OK to use for bigger fish?

Are they safe (relatively speaking) on the local rivers? I'm sure it depends on where and conditions but I don't know what they might be.

Easy to transport?

Types and sizes recommended?

I don't even know enough yet to ask intelligent questions. Any advice or recommendations are greatly appreciated.

Thanks,
Bill
