For some time I've been looking for a "new-to-me" cruiser style boat. The Marinette really stands out as a affordable and maintainable platform. Besides, I like the classic

I've owned a 22.5' runabout for 1.5 years now and it's just not the best fit for how my fiancee' and I use it. We spend maybe 80% of our time cruising and occasionally do a little wakeboarding or tubing. The thing that our current boat doesn't do very well is cruise... My little 22.5' boat really struggles in the chop on Trinity and Galveston Bay near the Houston Ship Channel. Also, we have to rent a cabin for longer stays at the lake, which adds up the cost and hassle of a weekend getaway. We'd really like a boat that we could stay aboard for 2 or 3 nights at a time. Specifically, the idea of hitching up the boat, leaving town, and plunking down at the lake/bay for a long weekend without having to rent a cabin is very appealing.
The 32' M's look like just the ticket except for the wide beam that requires an oversize permit to tow. I seriously considered just dealing with permits, but decided that many of the restrictions wouldn't allow me to actually use the boat as I/we would like. Here's where I need some advice: I am looking at buying a 28' Express to meet most of our wants & desires, then considering modifying it to make a trailerable boat into a weekend-liveable boat for 2 people.
This brings up a few questions:
- Will the 28' Express (single screw) maintain just about any displacement/semiplaning speed or do these boats have a distinct on plane/off plane speed range? My current boat either wants to go less than 9 MPH or over 19 MPH. Cruising at any speed in between is completely out of the question. This is very problematic in windy conditions or when attempting watersports activities... Notice I say attempting

- Does the Chrysler 318 c.i. in a 28' Express have the power to pull up a skier? Thought: I could affordably build a 408 c.i. stroker... (used to be an engine builder and have some experience with these little 318s)
- Is the cabin comfortable for two adults, one being 6'2" tall? Headroom and V-berth room are my main concerns.
- What changes are required to accomodate overnight/weekend stays for 2 people? As I understand, water capacity may be the biggest hurdle to overcome.
- Does anyone know of a 28' Express for sale anywhere near Houston, TX? I'd be willing to drive a few hundred miles to pick up one in good condition.
Any advice is greatly appreciated!
