Seller's Description

The Sanibel 17 is a well designed, easy to trailer, and easy to sail boat. With a total towing weight of under 2000 lbs on the trailer, it can easily be towed by almost any vehicle. The nearly 8’ beam creates a spacious cockpit that comfortably seats four, and the the high combing keep the occupants dry. 400 lbs of ballast in the keel makes it stiff and comfortable in a breeze. Lifelines and bow and stern pulpit add an extra measure of safety for cruisers with children. The offset centerboard design hides the trunk under to port berth, opening up the cabin which features four opening portholes and a forward hatch for sail camping. Sail suite includes main, jib, and 135 genoa, all in good condition.

Nearly every part of this boat has been gone through in the last year. Here is the complete list:

*Bottom completely refinished with 3 coats West System barrier coat epoxy and 4 coats Pettit Vivid *Centerboard and rudder faired and refinished *Weak factory centerboard pin removed, adding 3/4” reinforcing plates and bronze bushings *Custom made reinforced outboard transom plate with brand new aluminum outboard mount *All new custom running rigging (Samson) *Portholes removed and resealed with 3M 4200UV *Brand new Bomar hatch *All deck fitting re-sealed with Bed It Butyl tape *All lines led aft to cockpit *Adding topping lift and boom vang with all new Harken hardware *Cabin cushions washed

The trailer was gone through as well, with the following work done

*Brand new LED light and wiring harness *Brand new jack and winch *Brand new Stoltz keel and bow rollers *New radial tires

The 2014 Yamaha four stroke has almost no use, and was just gone through with

*New spark plug *New external fuel hose *Lower unit and engine oil change.

Have 2019 Maine registration in hand. No projects, no work to be done, just hit the water on your next adventure.

Calculations

Hull Speed
6.4 kn
Classic: 5.2 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

6.39 knots
Classic formula: 5.2 knots
Sail Area/Displacement
22.1
>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.
22.06
<16: under powered
16-20: good performance
>20: high performance
Ballast/Displacement
32.9
<40: less stiff, less powerful

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

32.85
<40: less stiff, less powerful
>40: stiffer, more powerful
Displacement/Length
179.0
100-200: light

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
178.97
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
8.6
<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
8.55
<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
2.8
>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
2.81
<2: better suited for ocean passages
>2: better suited for coastal cruising

Notes

The SANIBEL 17/18 derived from the SKIPPERS MATE, built by Southern Sails Inc. of Clearwater, FL. By 1984 it was the COMMODRE 17, built by Commodore Yacht Corp. of Saint James City, FL. In 1985 Captiva Yachts began building it as the SANIBEL 17. In 1986 the name was changed to the SANIBEL 18 although it wasn’t until slightly later that a number of changes were actually made to the design.
Another set of molds were created from an existing SANIBEL 18 by Leisure-Time Fiberglass Products of Cadillac, Michigan. Their version was sold as the SNUG HARBOR 18 though very few were built.
