Lots of engineering and only good for long tacks. Just offer free beer and get some rail meat.

Yes, that is the best set up for sure - that is how the MacGregor 70 works. (It's also got a huge generator that can make that transfer from side to side really fast). And my understanding of the MAC70 system is that you don't need to use it. Apparently it's an additive type of ballast trim system. I sure would like to see that go in person but I don't know where I could see one.

I had a Siren 17 ft trailer sailboat with a steel swing keel 300# approx on a winch it came with a lock down bolt for deep water sailing so if u turtled it was locked down so it was not going to be swinging back & crash into the keel slot , so the 300# keel would stay up-right if turtled & help in righting the boat , but I must say that Boat could pretty much handle anything if the skipper was qualified although would be a wet ride LOL

I don't remember seeing anything about movable balast on the 65' 70'?

Not on the 65, on the 70. Two different boats.
See the video about the transferable ballast from Captain Mike Inmon on You Tube

That video is 3 years ago. You live in that neck of the woods. Any news on it?

Yes, it's a boat that Roger is building about 100 of them - I think all the current production is already sold - and they do indeed have transferable ballast.
Mike Inmon is the salesman for the boat.
As they work through production I guess they get more customers - I'm not really sure how yacht sales work when you get up into those really big boats. You would need to talk to someone a lot richer than me.

From what I remember Mike saying they do not make really large modifications for customers because it makes the price too high. Much like the 26 the tooling is created once and used on all boats.

Oh yeah, that's fer sure - your right on that one - and I think Mike said they do offer a few different floor plans and interior textiles have some selection too.
The 65 had two floor plans, One had a pilot house and the other had no pilot house and a bigger galley.
