Stu I think you should re-think taking a 14' fiberglass out on the chuck. Especially with family and no boating experience. I don't feel the risk is worth the reward. Spend some time on a few lakes getting used to the boat and the motor and how it acts and reacts to wind and waves. It is better and safer to know how the boat reacts when someone moves fast or leans when the potential for disaster isn't as final, not to say swamping a boat out from under you isn't dangerous on a lake.
Once you do get familiar with how the boat and motor acts they are a great way to spend the day with the kids. Whether you fish from an anchored location or troll plus it is a good way to keep an eye on the smaller ones.
Here is to lots of fun days out with family and good fishing.
I second this, its a great post.
Also, before you go fishing in it, get to know it and take it out a number of times without the gear. Fishing from a boat can be a management nightmare if you are not comfortable with it from the get go. It is really important to be comfortable with the way your boat handles, and to be able to predict how it will handle in different situations.
It is a lot like driving a car really, you don't start by taking it downtown and getting a job as a courier... you learn in a parking lot, move to the rural streets, then busier, ease into it. Sure you can go right into the city etc. but you're more likely to get into an accident if you're not first comfortable with it.
Once you are comfortable with the boat and ready to hit the chuck, there is plenty of fishing you can do without a downrigger. You could go jig for feeder springs off of bowen, for example, or, you could run slip weights on your line....that's how we used to do it before downriggers came around. It would work just fine when the coho are around, thats for sure, 1 or 2oz slip weight and then 20 feet to a bare spoon. 14 feet is plenty of boat for inshore stuff as long as the weather is nice and stable.
