The south coast has heaps of room but is slower and won't point as well as the others. But is cheaper.

as I understand it they are all based on the Roberts 35 design hull...then fitted by Martz as a CC design, Southcoast as an Aft cockpit , with various ketch,cutter or sloop rigs. I would guess similar rigged boats would be fairly similar in performance.

Only basing on stuff from the web:

from the Roberts website

Roberts 35
<div>This is a classic modern design that has been built as a production boat in many parts of the world. Brett Martz used the centre cockpit version as the basis of his production design, the Martz Craft 35 and refined the accommodation to to one of the best 35 ft cruising layout around. A wonderfully safe cruising boat, with good performance on or off the wind, this design has many very attached owners.

<div>There were several SC 36s made to the original flush deck aft cockpit style of the original Bruce Roberts plans. I believe that this was changed to the aft cabin design very early in the production period and because the hull mould was altered to take the new deck mould, no more aft cockpit style boats were made.
I've attached photos of the SC36 aft cockpit version. The difference from the Roberts 36 is the extended and raised deckhouse of the SC36.

I would add a Zeston 36 to your list. Unlike a Roberts, Joe Adams designs a boat to sail really well.

Theres another one for the list - Mottle 33. (Adams hull design + George Mottle accommodation).

A friend sailed one Sydney to Vanuatu and back no problems. I had one, I liked its beautiful shape and slick Adams hull design. But being only 33ft it has lower hull speed than the 35's and 36's which makes a difference on a long trip. The aft cabin is also a bit small and low, but the Mark II Mottle 33 was bigger. It has a real solid keel and I knocked mine flat many times racing and it was bullet proof. It also got dragged sideways off a sandbar in the surf and was still fine.

You can hire a Mottle 33 at Lake Macquarie to try one.

Eventually I went for a Martzcraft 35 and I believe it is a GRP redesign of the Roberts 35. (But I will be corrected if that's wrong!). I can stand up in the aft cabin and saloon and sailing wise its faster than the Mottle was. Also the gf likes the bigger galley. Amazing to me it points well and even in a light breeze it goes OK.

South Coast 36 was always on my list. The extra space compared to Mottle and Martzcraft looks wonderful, and the fact that it would be impossible to fall out of that deep cockpit!

The Mottle is one of those boats that is such a good cruiser that its performance is often under-rated, especially because the cruising ones tend to drag big props, furlers, etc. With that fairly small rig and the large wetted surface they pick up at the stern if they are weighed down, they can lose a lot of performance. But when they came out they were a real breath of fresh air. At that time everyone was building IOR boats, and the wide stern and clean lines of the Mottle allowed to it often beat everything of its LOA, especially downwind in a breeze. Boats like Thermopylae, Follow Mee and (IIRC) Taveuni did very well in racing. I've looked at getting one a few times because well sailed and well equipped (ie kept fairly light and with good sails to make up for the small rig) they can move very well.

The big version, the GRP Adams 40 centre cockpit, is a stunning boat IMHO.

My father had a Zeston 40 (Dancer) which is now in Pitwater. A Zeston 40 will run rings round all the other boats mentioned above in build, sailing and comfort. Zeston's were built by Eddie Buzzen and are the predecessor to the Buzzen 40, 48 and 52. Zeston' s are a cut about the rest and worth the little extra money you might pay.
