That hull damage under the 'jackstand' can be repaired - probably also has gross delamination in the adjacent area and you'll not know how extensive until you 'open' it.
Id be far more keenly concerned with that crack at the top of the encapsulated keel
ballast, as this is a MAJOR MAJOR issue and in an extremely stress sensitive / stress critical area. Further and especially if water has penetrated into the ballast 'cavity', and if the ballast is iron and is now 'rusting' such an extensive repair can possibly only result in a 'heartache' when the rust continues to 'push' that encapsulation apart and 'down deeper' than that crack.
That keel crack is along the upper top margin of the ballast -- such a repair there is going to have to be critically
'awesome'. IMO - this keel crack is suggestive of a complete structural failure
, not fixable via a simple cosmetic repair.

If the ballast is LEAD, then you have a minor chance at restoration; but, this is going to involve some pretty 'severe' repair and unless you are 'very good' with tapering and precise epoxy fiberglass repair work and are very precise at restoring back to the OEM structural
geometry and surface curves at the turn of the bilge and deeply into the hull ... Id make the suggestion to look for a hull that isnt 'totaled'.
