I don't think the Freedom 33 will be much like my M except for the trailering, and that will require a decent 8 cylinder. It requires more than three times the water ballast at the waterline to gain the same stability you get just 3-4 feet lower. You just can't do that with water ballast and sail in light winds. The Hobie 33 was given a 122 phrf for lake Dillon last year. This is probably more in line than the 87 she carries for the ocean. That is still way beyond the 250-270 carried by the Mac X or M. I saw the video where Hobie repeatedly ran the 33 aground with no ill effects, too prove it's soundness. I wouldn't want that changed. There just aren't a lot of off-shore, capable trailerables around with lifting keels of any size. I like to sail and If I could motorsail above 9 kts. I could still get around pretty well , but it's not the 15 plus kts. you'd expect from a Mac.

Are you the bloke who I had a chat with as I was packing up on Raymond Island?
If so it was a pity we were both pressed for time as your concerns about water and head aren't a problem and I could have given you a tour.
Can you update your details on the profile for location etc also there is an Aussie section which you can subscribe to so you can find out where :macm: 's may be meeting for a look.
Hopefully I will be going to the Geelong Trailer sailor festival again if I can get my mods done in time so a sail could be in order.

Thanks Art.

You have a following here.
- We need our 33' QM update :!:

Art,

I was reading through everything again. I was curious about the engine. You said that it will not take more than a 20hp engine. Do you mean it won't take anything bigger, just like the 26M isn't supposed to take anything bigger than a 50hp? I know we are not working with a planing hull so strapping on a 100hp motor after beefing up the transom isn't going to do much of anything. I am just wondering what is the constraint that keeps anything bigger from being put on. Transom strength, shape, etc? Just curious really.

Once you see photos of the new transom I think you will understand. :wink:

The boat is considered an ULDB and was designed to sail fast. Especially off the wind. It is very similar in concept to the MacGregor 65. Very light and narrow.

It all boils down to balance. If you start adding a lot of weight to the stern the boat will start to have handling & control problems. Excessive weather helm and rounding up just to name a couple.

If you were to put a large engine, fuel, Edson pedestal steering and an average sized human at the stern you would end up with some real issues. Probably somewhat akin to a motorcycle doing a wheelie.

OOOhhhh.....Wheelies are cool! Seeing a 33 foot sailboat cruise by at 30 knots with it's nose 45 degrees in the air would really shut the other cruisers up. Count me in.

I just ran across this thread… where have I been!

I love it. Unfortunately, timing is everything in business. Before the housing debacle and my purchase of an ’08 26M, I would have gladly bought this boat.

Economies of scale make a huge difference in production costs. My base Mac was $20K. If I could get this boat with the equivalent exterior pieces (boat, trailer, rigging, main, no-engine, etc) and absolutely NO interior, I’d be happy as a clam. I’d fiberglass and wood up the interior, add the go-faster pieces at my leisure… in the ten year plan. Could a stripped down version (without interior) be created for even twice the price… $40K? Again… Roger’s mass production is hard (Hunter would say impossible) to compete with.

Unfortunately, IT IS after the housing debacle and I have a ’08 26M, I probably couldn’t get half of what I have into it. So I’m on the sidelines looking in…

… so I’ll arm-chair quarter back.

1) Have you considered using a resin infusion process. I’ve been designing a 40’ catamaran, using stitched instead of roving and epoxy instead of polyester. The result is a single hull goes from 1300 lbs to 670 lbs with an increase in strength, water permeability and several other benefits. It may guarantee keeping the boat light for both the performance reasons and not having to bump people up from mid-level SUVs to heavy duty pick-up trucks.
2) Considering how short and stubby a 26M is, it is remarkably cosmetic. Maybe I’m just a little partial. But you need to make sure you nail the topside, or you’ll just have another cargo container. Seems like someone (who has an eye for lines) needs to define the topsides, so you’ll know what you can do below.
3) I understand very well why you can’t change anything your tooling defines… width is fixed! Way too many things can get screwed up by trying to add even 6 inches. and the ONLY reason you might be able to get it even near our price range is the fact that all the fluid, strength, and stability analyses and all the tooling is ready to go…
4) Have you considered taking advantage of the extra height you’ll be adding in the cabin to allow the keel to be that much taller (and thus deeper)? Sounds like you could add two more feet of keel for that much more righting moment and… performance, stability and forgiveness.
5) Have you considered a semi wing type keel?... not so much for the fluid dynamics as the flatter, tucked up against the hull form factor. You might be able to lower the entire boat down on the trailer by nearly a foot with the resulting easing of launching per Roger’s 1” equals 1’ down the ramp theory.
6) Interior… I really like the curved designs. Have you considered the keel has to come up through there all the way to the roof, so the table and seating have to be cut to allow the movement?
7) I started a 3D drawing, but the accuracy available from the line drawings on the Internet are not good enough to get the hull contours right which is important to determine interior volumes.

Maybe, my 401 will recover and I can still get one.
