1984 Frers Tri-Star

Sarasota, Florida





"Osprey" is an ocean cruising ketch rigged sailboat built like a tank! She has only seen 1-owner since new and has around 80,000 miles under her keel.  She is in vey nice condition and is priced to sell due to the current owner passing away recently.  She has a great 2-cabin layout with 2-heads and 2-companionways. The teak decks were professionally removed as was the balsa coring. A water impervious coring was then added (resin) and refinished with non-skid.  For someone looking for a serious offshore yacht with a performance pedigree, look no further!

While efforts are made to keep this listing up to date, information provided at the time of listing is subject to change if the vessel is on the market for an extended time.  A buyer should instruct his agents, or his surveyors, to investigate such details as the buyer desires validated.

The Tri-Star 48 is truly a performance "racer/cruiser."  Its variety of sail combinations allows it to do 175nm days and cruise easily at 8 knots.  Its waterline/beam ratio of 2.57 gives it a hull speed of slightly over 8 knots and a low PHRF of only 101.  Simply put, this boat is fast, sea kindly and safe!

The boat was built for long distances.  Its tankage holds 170 gallons of water and 110 gallons of diesel.  That much fuel will allow motoring 400nm with a safe reserve.  Its large refrigerator and freezer, both cooled by cold plates powered by an 8kw generator will keep perishables cold and/or frozen for a long time.  The boat sleeps four forward and aft berths plus two more in the salon

The nav station has a large chart table and redundancy in all the latest navigational instruments.  When you get to your destination there is plenty of room to entertain in the sumptuous salon that seats six at the drop leaf table under a large, brass oil lamp.  In addition to the aft cabin companionway there is also the main companionway to the salon to provide privacy in the aft cabin.  Both cabins have en suite heads and showers.  This boat is friendly for the Captain and mate, crew and friends.

Only two of these boats were made.  The hull and deck were laid up and the bulkheads all bonded together, the engine and tanks installed and the interior finished in Taiwan.  The two were then shipped to Annapolis but, unfortunately, the builder spent so much money on German Frers custom design and solid, safe construction that no more were built.  The single owner purchased Hull #2 in 1988, installed masts and rigging and lovingly sailed and cared for the boat until his untimely death in mid 2020 when he was prepping the boat to go again

Accommodations & Layout:

From forward:

Huge sail locker in the forepeak, which is accessible from on deck through a 30" x 30" Bowmar hatch or through a door into the forward head and shower area.  There is a 24" x 18" work bench with 4" vise and a Shurflo wash down system for the anchor

The head is located aft of the sail locker and has a Wilcox Crittenden "Skipper head with a macerator and Y-valve, 12" oval SS sink and a fan, 20" x 15" Bowmar March and a dorade.

 Next aft is the forward stateroom with the berth offset to starboard and a settee to port..  

Further aft is the main salon featuring a sette to port and starboard with a huge drop-leaf table in between, which can easily accommodate 6 for dinning.  Ample storage located throughout.  There is a brass 18"x12" hanging oil lamp, 22" x 22" opening Bowmar hatch and 2 x dorades.  There are also 2 x 12V Hella fans and 4 x large side ports.

The U-shaped galley is next aft to port with a Force 10 3-burner, electric start stove/oven, two 20# aluminum propane tanks, Trident Marine propane control system w/light, Panasonic 1200-watt microwave; SS Elkay wide, double basin 29" x 18" sink with a Delta single handle faucet Grunert "Passagemaker" AC475 refrigeration and freezer system with a March LC-3P water pump.  The refrigerator is front and top loading and measures 18" w x 20" l x 29" d - the freezer box is top opening and measures 18" w x 20" l x 10" d expandable to 29" - both boxes have 4" insulation.  Dual gauge trip hose refrigeration kit with 24lbs of refrigerant.  In counter trash bin, dorade, fan and hatch

The navigation station is adjacent to starboard.  

Between the nav station and galley - over the engine is the forward companionway with stairs that hinge up to the ceiling and out of the way when accessing the engine

Aft of the navigation station is the walk through to the aft cabin - in the walk through you will find an office/desk area.  

Aft Cabin has a berth offset to port, with a custom mattress and a seat to starboard with a large locker aft.  The aft head is located just forward of the berth and next to the engine room.  The second companionway is located here

The cockpit features lattice teak sole, raised helm seat with cushion and side cushions

Fold up teak 25" x 30" table, 3 x cup holders and binocular holder

There is a helm sailing Bimini, cockpit Bimini w/side, privacy curtain

There is an abundance of storage throughout - from bow to stern and side to side.  The interior is in very good condition and was well taken care of by her only owner.
