Re: turning a sailboat into a motor cruiser
if you REALLY want a project, here is a labor of love. I think this is a Gougeoun Brothers cedar strip boat. It is probably fast as heck. Its so sad to see it like this. Also at Torresens. Make an offer. Offer to haul away.

Re: turning a sailboat into a motor cruiser
I think your idea is sound, and that you can end up with a good boat. As with all things nautical, details make a lot of difference. Here are some thoughts and suggestions.
As several posters have said, a sail hull can be a very efficient powerboat when operated at the low speeds it is designed for. Specifically, if you want to keep the fuel consumption low you will want to operate at a speed/length ratio not over about 1.1
You do not want a deep keel. This, when full of ballast, lowers the center of gravity of the hull. The lower the center of gravity the faster the roll period. You do not want a fast roll period. A long and shallow keel will help damp rolling and will reduce your draft for shallow water. Look at a lot of the older, displacement power boat hulls.
I'd strongly recommend that you keep some of the mast. You can have a cut down rig, much lower than the original, with small sails that are easy to handle. The main reason to keep some rig is roll control. Those sails sticking up in the air are very efficient roll dampers. Pure power boats commonly have to resort to towed roll dampers to stop the roll. A small rig will do this well and will often increase your speed/decreasee your fuel consumption. Plus if the engine fails you're not helpless, you can still sail to port. I promise you this will make the boat a lot more comfortable out at sea.
You'll want a decent fuel tankage.
The ability to swing a larger diameter prop will greatly increase the powering efficiency. Most sail boats have props that are way too small for good efficiency.
I suggest you buy the book "The Nature of Boats" by Dave Gerr. He addresses a whole lot of things that will help you understand how to make this project a success. And he does it in an easy to read manner.
Good luck,
Paul

Re: turning a sailboat into a motor cruiser
Do you mean Gougeon design or just an epoxy strip planked boat, which is not "Gougeon " at all.

Transom steps are a monumental cockup, should have been recessed in not just plonked on the outer as some sort of afterthought.

Years ago I considered taking a 19' Hobie and adapting that to a 36' sailer and then whacking off the keel.
Then there is this route for less money..........

I can't say for sure. If you are interested, E-Mail Torresens in Muskegon. It looks like one of their boats. It is about the right vintage. It carried a very high aspect rig and was rumored to be a fast racer. We ran into a couple of them racing on Lake Erie many years ago and they looked like this. They always saved their time. Gougeon is a Michigan company, just across the state from here. I think the transom steps were added on. They definitely don't belong. Every time I lust after it the admiral snaps me back.

Re: Turning a Sailboat Into a Motor Cruiser
i am so glad that i finally posted in here, thanks to all. ,, so to bring me up to speed, David_ol_jersey OP? is this me? spanners is tools? thanks ElgatoGordy for the strawlering post and duckworths website, Pauls i really like your idea about the longer keels but shallower,
the reason i have posted here is that i will not have to learn the hard way, i resigned from the school of hard knocks ( hopefully ) so i acknowledge the need for a sail if only to help stabilize the boat. and i promise that when i make a offer for a boat i will have the ability to pay up on the spot. okay? now about the $35000 I do NOT want to spend near that amount on the boat if i can avoid it , $3500 would feel better, then install the toys i really want , such a compressor for filling scuba tanks etc.... chart plotters, radar, the ability to add extra tankage for fuel 2-3 banks of batteries for electrical needs these 2 things are the most priority on my list as of this moment, i did post so i could sorting things out and learn from all, btw the discussion about fuel economy in "displacement hulls vs any other hull type" has been settled a long time ago, plus i would very much like to find a 50ft or better if possible on the hard dirt cheap, that is why i listed $35000 as a base price

Sounds like you will be adding a bit of weight so length will help.

Yeah, OP = you! (Original Poster)
Spanners = Tools.
One thing to bear in mind is that whilst many things can be done - not everything is a great idea.
Nonetheless I think your idea has some merit if you can stumble accross a good deal (and accepting that the end result will be less than ideal), but I would favour going the trawler (or large motorboat) route. But at the end of the day not my money!

Re: Turning a Sailboat Into a Motor Cruiser
Go to boatyards. There are usually many lost dreams that are taking up yard space that the management would like seeing go away. I picked up my current project boat for the back storage fees that were due. There were many to choose from.

I'm certain most of us here would agree but two bits says the OP could not care less and thinks it's a silly notion.
Every post above about trawlers being better/roomier is true and the only person who doesn't believe them is the OP. He's still attending the School of Hard Knocks even if the address has changed.
Here's two other issues he'd swear won't bother him. He just wants a cheaper way of life. There will be much more of this in the future, I predict.

The Strawler does remind me that taking one into a marina might be like driving a schoolie converted as an RV into the RV park, many are turned away.

Plus, while his mileage may vary, I've found a sailboat is much more hassle to dive from, as well as fish from, and most everything else. The OP better save a few bucks for bow and stern thrusters for that 50'er too.
