May be in the market, again....

I have an Offshore 62 as well and love it, like you I'm looking at possibly making a change as well. I'm looking at express style boats in the 50 - 60 foot range. My issue is Air Draft and the PCH Bridge, there are way too many days I can't get the Offshore under the bridge or I have to move it to our Yacht Club the day before etc. If we are going to the island.

The OP's post reminded me of the across my canal neighbors. Wife wanted, Wife wanted, Wife wanted. Hubby gave in and bought the one she wanted and of course paid too much. For the past several years its become a dock "extension," as she lost ALL interest in boats.

I have run ALL of those boats mentioned long distances with the exception of #4 and #6. The Hatteras 60' is by far a much better riding yacht than the others mentioned, by a long shot due to it's beam and size. The 52-55' Sunseeker and the 55' Princess are both too heavy for their hull design and the ride suffers because of it, they tend to roll in a stern quartering sea and they ride like a much smaller yacht than the Hatteras and storage is at a premium. Although I think I'd take the The 60' Princess is fast, but pounds so doesn't ride great either. I'd take Riviera over Maritimo by a long shot, but totally differing design. Horizon I cannot comment other than dockage can be a big problem, but tons of space on the FB and aft deck and salon, staterooms are very funky though due to cat attributes. If you're willing to go there, a 66' Sunseeker manhattan with the sidepower curved stabilizers is an amazing running yacht and terrific at anchor and slow speeds and much better staterooms than the others mentioned.

With your list here is what I see working, I have not traveled or helmed any of these, Capt J has that covered.

I can't think of anything you are not thinking of as far as bulid/yards.

Princess S60 or F60, I like the S60 still has a fly sport bridge and lower helm but not the massive way up high overweight flybridge hardtop that would contribute to rolling.

Fairline fits the bill except VP power.

Are not a lot of boats with zero speed stabilizers IPS drives as well?

The 60' Hatteras upper helm is fully enclosed with strataglass and air conditioned, a compromise yes. However on the 64' Hatteras some had the lower helm and rarely ran them from there. I would run the Sunseekers and Princesses from the lower helm very often. The Riviera has a better ride than the Maritimo's I've run. The S60 Princess is fast, I've run one about 400NM in different sea states, but pounds in very moderate seas. The F55 and 52' and 55' Sunseeker all are too heavy for their hull design and tend to feel like it at sea but I think the Sunseeker is a little better running and much prefer it's engine room and crew quarters, I've run all of these and 60' Hatt a few thousand nm's. You could fit any of these boats mentioned INSIDE of the 60' Hatteras, it's a much bigger boat, much more range, and a real yacht compared to the latter ones. I would go with that regardless of not having a lower helm.
