You are very unlikely to find this unless a previous Sadler 34 owner has had the inclining test done and a STIX number calculated.
The RYA are trying to put together a database of STIX numbers on boats currently in production, but it would appear that manufacturers are being less than co-operative.

Why do you need a STIX number anyway? The Sadler 34 is generally accepted as an excellent ocean crossing platform - I wouldn't have any worries offshore in a well equipped example in good condition. They have made many Atlantic crossings and at least one circumnavigation - and of course they are theoretically unsinkable due to the double-skinned construction. In October 1987 a Sadler 34 was rolled through 360 degrees while caught in a hurricane in the bay of Biscay and sailed home undamaged by the experience. (Source: Article, PBO May 2002)
There will be a difference in the AVS and STIX number depending on whether the boat has the deep or shallow fin keel.
Hi Nick
have just sold my conway and am looking for a sadler 34 with a long or steven jones keel. The reason for my question was mainly out of interest, I see from the ym sept 20002 that the contessa (which the sadler 32 replaced) has a STIX of 31 to 33. It was merely idle curiosity that prompted the question. I will check out those sites. Thanks
