For an outboard I was thinking of getting a Yamaha 25hp 2 stroke, or a 15-20hp 2 stroke but am finding it pretty hard to find any 20hp units - thinking that a 15hp would not be quite big enough? The 25 comes in at 50kg which is within the limits for the transom. From looking on here this may to too big (weight wise) to be manageable?
I've tried various combinations over the years in pursuit of the perfect compromise (because it will always be a compromise between space, performance, ease of use, and storage).
I've had inflatables up to 4 metres, with wooden floor, ali floor, flat airdeck, and Aertotec airdeck. I've also had a Tinker Foldaway RIB and a little folding transom RIB.
If you're going to be packing it away each time then I would get an Aerotec 380 with a 15hp 2-stroke. If you can leave it inflated on a road trailer, then I'd get something like that 4 metre Avon with a 25.
You should find that in good conditions you'll all be OK in either, but you're unlikely to want to go on any extended trips. If the conditions are not so perfect then you won't all want to be going out in an inflatable anyway. Performance fully laden isn't going to be great, but you can always take the kids out for a spin one or two at a time.
Don't be over ambitious with the children though - leave them wanting more and they'll grow into it. Try to do too much too soon and you'll end up being the only person in the family who wants anything to do with boats at all.
