I own an Allweather.
My wife and I cruise in it each summer (with a small dog). We've been down Hood Canal and up to Princess Louisa (limited by my vacation time). Pretty pokey and it'll roll, but we've never been frightened. Mostly we hop between our favorite islands, towing a dinghy, like most people do in the northwest.
Compared to a larger boat, the cabin puts you inside the hull, versus perched on top the hull. We sleep about 12" above the waterline.
We use a composting toilet to avoid a holding tank.
Cheap propane oven/stove. No heat, no hot water.
Water tank is proportioned too small compared to the fuel tank, at least for the northwest.
The stern is not so fine as folks suggested. Certainly a double ender, but the bow is a lot pointier (much fuller than, say, the pictures of Nimiane).
A previous owner did a lot of fishing, and the looks haven't been well maintained.
I've done some small work on the engine and rewired the electrical. All easy enough.
We don't keep it on a trailer, so I can't comment there.
It's slow enough that you need to pay real attention to the tide, which makes planning more interesting (in a good way). All in all, it's rather like cruising in a sailboat, running under the auxilary (like many people do in the northwest, since there's often too little wind to sail).
Plenty of room and plenty of speed for our sort of cruising.
I still like it.
