I only need a top end of about 20-some kts with a 15-17kt cruise, really, an old fashioned easily driven hull is what I am looking for. The problem is that to make a good cruiser for 2+ week trips I need about 29 to 30 feet, and just to make things harder I would want outboard power. This boat will be just too small to fill the ****pit with an engine box, I also suspect that a pair of outboards will be quieter at cruise, at least from the inside helm and I am not planning on an outside steering station anyway. I also like the redundancy of twins too.
This will be a boat for remote exploring and will be away from the marina for weeks at a time. Thus I need sufficient freezer and fridge space as well as a shower. Fuel and water can be found w/o too much trouble in SE Alaska, but there ain't too many laundromats or grocery stores up there. All this means a 25 foot hull just won't work AFAIK.
