2006 Gemini Telstar 28

Listed
Expired
$50,500 USD

Seller's Description

This is the Tony Smith designed Telstar 28 Trimaran. The boat has the one-man mast raising system and folding amas that go from beam of 18ft to folded 8’6”. This makes for easy trailering as proven with the Claudia Mae making 4 cruises of Lake Michigan, participating in the Dauphin Island Race and venturing from Mobile to the Florida Keys not to mention local lakes. The trimaran has a centerboard that goes from 4’6” down to 1’ up—-this made for great gunkholing through the Everglades and Keys. The Trimaran has a tiller which links to the Honda outboard to give exceptional steerage when utilizing the outboard. This trimaran makes the ideal boat for trailer sailor as the Venture dual axle trailer is included and in very good condition. The Claudia Mae is a very comfortable boat with sea kindly motion and she is fast as she has a main, 150% genoa, screacher and spinnaker. This trimaran is the ultimate gunkholer that can be easily trailered and set up.

Additional Details

Layout & Accommodations

This trimaran has 1 settee bunk on port and 1 on starboard with a folding table between settees and above centerboard. The folding table accommodates up to 6. The forward cabin is separated by a curtain and has the marine head, a sink and small berth. Immediately to port upon entry is a 2 burner LP stove and broiler. Immediately to starboard upon cabin entry is the nav station, 2 batteries with controller and breakers. The boat has comfortable 6-foot headroom throughout and 2 Bomar hatches for ventilation.

Galley

The galley is located immediately to port upon cabin entry and is equipped with the Taman 2500 LPG 2 burner stove and broiler. There is also a Engel refrigerator located above stove that has never been used and would be questionable if cools. There is also a single sink located in this area. The area and boat has dome fixtures for lighting throughout. There is teak drawers and sliding compartments for storage and under sink storage.

Deck & Equipment

The deck has stainless handrails along port and starboard walk areas making for safe at sea conditions. The 150% genoa is controlled by port and starboard Lewmar #40 AST winches and the mast 2 Lewmar #7 winches. The jib is controlled by rolleer furler. The amas easily fold by releasing the controlling line in the port and starboard cockpit compartments. This can be done when on water and allows use of a normal width slip if needed.

Electronics & Navigation

The electronics include Ray Marine ST 60 TriData windspeed and depth. Ray Marine 54 VHF. The trimaran also has the Ray Marine ST1000 Auto Pilot. There is also a Contest 4 inch compass mounted on starboard cockpit.

Electrical, Power & Plumbing

The Telstar 28 trimaran has 2 lead acid batteries that powers electronics and outboard for the 12 volt system. There are 2 banks with 1 battery in each and controlled by the Blue Sea battery switch. The trimaran has a marine toilet with a 13 gallon holding tank. There is a 16 gallon fresh water tank that supplies water to the two manual pump sinks and for a fresh water flush of the head if desired.

Engine & Mechanical

The Telstar is powered by a Honda 4 cycle 20hp outboard with a 6 gallon tank. This engine allows for a cruising speed of 6 MPH. The outboard also keeps the batteries charged when in use

Sails & Rigging

Sails include a Bierig main, Bierig 150% genoa with roller furler. A Bierig laminate spinnaker and a Bierig laminate screacher. All sails in good condition. All rigging is dacron braid on braid.

Additional Information

The trimaran Claudia Mae finished a cruise from Goodland Florida through the Everglades and to Marathon Florida and back. She is now ready for new adventure.

Calculations

Hull Speed
11.3 kn
Classic: 6.9 kn

Hull Speed

The theoretical maximum speed that a displacement hull can move efficiently through the water is determined by it's waterline length and displacement. It may be unable to reach this speed if the boat is underpowered or heavily loaded, though it may exceed this speed given enough power. Read more.

Formula

Classic hull speed formula:

Hull Speed = 1.34 x √LWL

A more accurate formula devised by Dave Gerr in The Propeller Handbook replaces the Speed/Length ratio constant of 1.34 with a calculation based on the Displacement/Length ratio.

Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio.311
Hull Speed = Max Speed/Length ratio x √LWL

11.25 knots
Classic formula: 6.9 knots
Sail Area/Displacement
40.3
>20: high performance

Sail Area / Displacement Ratio

A measure of the power of the sails relative to the weight of the boat. The higher the number, the higher the performance, but the harder the boat will be to handle. This ratio is a "non-dimensional" value that facilitates comparisons between boats of different types and sizes. Read more.

Formula

SA/D = SA ÷ (D ÷ 64)2/3

  • SA: Sail area in square feet, derived by adding the mainsail area to 100% of the foretriangle area (the lateral area above the deck between the mast and the forestay).
  • D: Displacement in pounds.
40.3
<16: under powered
16-20: good performance
>20: high performance
Ballast/Displacement
?

Ballast / Displacement Ratio

A measure of the stability of a boat's hull that suggests how well a monohull will stand up to its sails. The ballast displacement ratio indicates how much of the weight of a boat is placed for maximum stability against capsizing and is an indicator of stiffness and resistance to capsize.

Formula

Ballast / Displacement * 100

?
<40: less stiff, less powerful
>40: stiffer, more powerful
Displacement/Length
71.9
<100: Ultralight

Displacement / Length Ratio

A measure of the weight of the boat relative to it's length at the waterline. The higher a boat’s D/L ratio, the more easily it will carry a load and the more comfortable its motion will be. The lower a boat's ratio is, the less power it takes to drive the boat to its nominal hull speed or beyond. Read more.

Formula

D/L = (D ÷ 2240) ÷ (0.01 x LWL)³

  • D: Displacement of the boat in pounds.
  • LWL: Waterline length in feet
71.9
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
3.7
<20: lightweight racing boat

Comfort Ratio

This ratio assess how quickly and abruptly a boat’s hull reacts to waves in a significant seaway, these being the elements of a boat’s motion most likely to cause seasickness. Read more.

Formula

Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam1.33)

  • D: Displacement of the boat in pounds
  • LWL: Waterline length in feet
  • LOA: Length overall in feet
  • Beam: Width of boat at the widest point in feet
3.65
<20: lightweight racing boat
20-30: coastal cruiser
30-40: moderate bluewater cruising boat
40-50: heavy bluewater boat
>50: extremely heavy bluewater boat
Capsize Screening
5.0
>2.0: better suited for coastal cruising

Capsize Screening Formula

This formula attempts to indicate whether a given boat might be too wide and light to readily right itself after being overturned in extreme conditions. Read more.

Formula

CSV = Beam ÷ ³√(D / 64)

  • Beam: Width of boat at the widest point in feet
  • D: Displacement of the boat in pounds
5.0
<2: better suited for ocean passages
>2: better suited for coastal cruising

Notes

An entirely new TELSTAR model (2003). (An earlier TELSTAR 9M was also designed and built by Tony Smith until about 1980.)
This version is ‘foldable’ reducing the beam from 16.0’/4.8m to 8.5’/2.6 m) for road transport and easier mooring where space is restricted. The Double-hinged beams swivel the amas alongside the main hull without extending the boat’s overall length.
