Don't know where you got those numbers from, but I know for a fact my 23Ft Hourston w/command bridge on the trailer weighs just over 3000Kg or 7000lbs on the Duncan truck scales. I would be surprised if the trailer weighed 2400lbs but it could I guess seems pretty heavy though. Just found this right off the Hourston website, they don't list the specs for the 20ft for some reason:
23’ SEDAN
THE 23’ SEDAN IS AVAILABLE GAS OR DIESEL, INBOARD OUTBOARD OR OUTBOARD ON A BRACKET. A FAVORITE AMONG FISHERMAN AND CRUISERS, THIS IS AN EXCEPTIONAL FISHING CRUISER COMBO. THE SPACIOUS CABIN AND LARGE OPENING WINDOWS GIVE THE CAPTAIN EXCELLENT VISIBILITY WHILE UNDERWAY OR AT TROLLING SPEEDS. WITH A 21 DEGREE DEADRISE THE VESSEL PERFORMS ECONOMICALLY WITH TWIN 115 OUTBOARDS OR A SINGLE V-8 STERNDRIVE. A 190 OR 220 HP DIESEL ENGINE (EITHER YANMAR OR VOLVO) WILL MAKE HER SUPER ECONOMICAL BURNING 3 TO 4 GPH AT CRUISE. THE CANADIAN COAST GUARD HAS MANY OF THESE VESSELS IN SERVICE ACROSS CANADA. THERE IS A WIDE RANGE OF DIFFERENT OPTIONS AVAILABLE ON THIS BOAT WHICH CAN BE CUSTOM SET UP FOR YOUR FISHING OR CRUISING NEEDS. ALASKA BULKHEAD AND HEAD IN VEE BERTH ARE STANDARD. THE PASSENGER SIDE FEATURES A HIGH LOW DINETTE TABLE, ON THE DRIVERS SIDE IS HELM SEAT AND FULL GALLEY. WALLAS DIESEL STOVE/HEATERS ARE AVAILABLE.
