Regarding the weight of a Super Seal 26, I think you are right to be working on nearly 3 tons for a boat in cruising mode.
I am basing this on the following:
In about 2008 another SS26 at my Club (diesel engine) was weighed on a load cell by an RYA measurer - 2750kg. The purpose was for the ISC RTI and would have been 'empty weight'. I helped the owner remove gear.
ISC definition - Empty weight is the weight of the boat in dry condition, fully rigged with all standing rigging, and spars
(including spinnaker pole(s)). It includes all permanent fixtures and fittings, batteries, main engine
installation, or outboard engine aboard in stowed position, but excludes all loose gear.
VPRS definition - loose gear - all sails, headsail sheets and guys, spare rigging, the contents of all tanks (including ballast tanks), anchors and cables, tools and spares. Additionally, all removable equipment (gas bottles, cooking and catering utensils, safety equipment including life rafts), all clothing and bedding, and personal effects, must be removed from the vessel.
My own SS26 LESA No 33 with Yanmar 1GM10 was weighed in 2006 by the previous owner for IRC purposes - 2925kg. This was done on a vehicle weighbridge and the weight of the trailer subtracted. Presumably again empty weight.
The weight data given in the SS26 specs on SailboatData and Yachtsnet at 2268 kg (5000lbs) is therefore high misleading - probably from the original brochure 40 years ago and perhaps for an outboard version.
I am sure my Bruce anchor is 7kg - it does fit in the locker with the lid down but only one way!
For your information, LESA's daggerboard (not a keel!) weighs 80kg. The ballast in the bottom of the boat works wonders.
Hope this helps - great choice of boat.
