Seller's Description

One of the nicest IP’s on the market. All of the IP weaknesses have been addressed. The glassed in chainplates were just replaced with titanium chainplates, the holding tank and water tank are brand new plastic/poly tanks, all new standing rigging, new autostream prop, hydrovane and many other major upgrades from an extensive refit over the past two years. I’ve owned this IP40 for about 5 years. She has been a great cruiser and I’ve made two ocean passages in her (1 solo). I recently just sailed her back to Hawaii. Selling to downsize, career changes are going to prevent me from the circumnavigation I fitted her for. The boat has lots of extras and a low time yanmar turbocharged engine. Also willing to negotiate price for delivery to the west coast or possibly deliver it myself.

Equipment: Refit, past 5 years most in the past year: Hydrovane Autostream prop Tri-mast light, led Led lights New spectra membrane new water heater New freezer and fridge units (frigoboat) New lifeline batteries 5x125amp/hr New cabin sole new plastic holding tank new plastic water tank maretron fuel and water monitor Viking 4 man open ocean life raft new 406 beacon emergency handheld desalinator achilles 10’2 dinghy 2016 Yamaha 6hp 4 stroke outboard new upholstery new instruments: B&G wireless wind and depth and speed transducer (waiting for haulout to replace current transducer, I have the brand new display and transducer in box), garmin 7608 chartplotter New galvanic isolator new shore power plug recepticle new bottom paint (3 mo ago) New head pump, aft head rebuilt new awning new pss dripless seal new extended safety rails (extended to allow future solar installation) New boom brake and vang new winch and rope cluthes added to boom for option of slab reefing from mast or cockpit. new running rigging new cockpit cushions new raw water and sewage lines AND many more smaller things too numerous to list.

Other equipment on the boat: SSB radio (Icom) w/ pactor modem Spectra water maker (dual pump) Gennaker Propane 3 burner stove/oven extra 406 beacon 2 main anchors plus stern anchor VHF radio balmar 100amp alternator Raytheon radar with two displays (this just went inop last month, I have not troubleshot it yet, it may me totally inop or simply a corroded connection ) Simrad electric autopilot foul weather gear and new self inflating life jackets with built in harness, tethers and jacklines lots of spares: alternator, thermostat, gaskets, valves, filters, o rings, hardware, belts, blocks, lines, sail repair items, etc etc Lots of tools to include dewalt cordless drills, Sawzall, bolt cutters, corded power tools as well. 1500w inverter 100 gal diesel bladder (new) plus jerry cans

This boat is basically turn key and ready to cruise. I’m more than willing to disclose my project list which is small.

The boat comes with everything you need to maintain it and cruise. I’ve replaced or rebuilt almost everything on this boat. Even most of the tools are new.

Calculations

Hull Speed
8.6 kn
Classic: 7.81 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

8.55 knots
Classic formula: 7.81 knots
Sail Area/Displacement
18.1
16-20: good 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.
18.05
<16: under powered
16-20: good performance
>20: high performance
Ballast/Displacement
43.9
>40: stiffer, more 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

43.86
<40: less stiff, less powerful
>40: stiffer, more powerful
Displacement/Length
259.2
200-275: moderate

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
259.21
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
32.3
30-40: moderate bluewater cruising 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
32.33
<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
1.8
<2.0: better suited for ocean passages

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
1.82
<2: better suited for ocean passages
>2: better suited for coastal cruising
