Summary Analysis of the Design Ratios for the Vindo 45

1. A Sail Area/Displacement Ratio of just 14.7 suggests that the Vindo 45 will need a stiff breeze to get her going. In light conditions, unless you've got plenty of time on your hands, motor-sailing may be the way to go.

2. A Ballast/Displacement Ratio of 42.4 means that the Vindo 45 will stand up well to her canvas in a blow, helping her to power through the waves.

3. A Displacement/Length Ratio of 303 tells us the Vindo 45 is clearly a heavy displacement cruising boat. You can load her down with all your cruising gear and equipment and it will hardly affect her waterline. Not an ideal choice for coastal sailing, but she'll come into her own on an offshore passage in testing conditions.

4. Ted Brewer's Comfort Ratio of 29.2 suggests that crew comfort of a Vindo 45 in a seaway is similar to what you would associate with the motion of a coastal cruiser with moderate stability, which is not the best of news for anyone prone to seasickness. 

5. The Capsize Screening Formula (CSF) of 1.9 indicates that a Vindo 45 would be a safer choice of sailboat for an ocean passage than one with a CSF of more than 2.0. 

The Vindo 45 Sailboat: A Classic and Comfortable Cruising Boat

The Vindo 45 is a 33'8" monohull designed by John H. Lindblom and built by Vindo from 1981 to 1989. 

The Vindo 45 has a spacious and cozy interior with plenty of natural light and ventilation from the deckhouse windows and hatches. It has two separate cabins:

  • one forward with a V-berth and
  • one aft with a double berth.

It has one head with a shower located aft to starboard. It has a U-shaped galley to port with a two-burner stove, an oven, a sink, and ample storage space. It has a navigation station to starboard with a chart table, instruments, and electrical panel. It has a large saloon with an L-shaped settee to port and a straight settee to starboard, both convertible to berths. It has a folding dining table that can accommodate six people. It has plenty of cabinets, shelves, lockers, and drawers throughout the boat for storage. It has an attractive woodwork finish with teak and mahogany.

Hull and Deck
The Vindo 45 has a solid fiberglass hull with an external lead ballast attached to the fin keel. It has a mahogany deckhouse that covers most of the coachroof and extends to the cockpit coaming. It has teak handrails on the deckhouse roof and teak toe rails on the deck edge. It has four opening hatches on the deckhouse roof and two on the foredeck for ventilation. It has six fixed windows on the deckhouse sides for light.

The Vindo 45 has a spacious cockpit with teak seats and sole. It has a single wheel steering mounted on a pedestal at the aft end of the cockpit. It has an engine control panel, a compass, and some instruments on the pedestal guardrail. It has two primary winches on the cockpit coaming for genoa sheets and two secondary winches on the cabin top for halyards and reefing lines. It has two large lockers under the cockpit seats for storage.

The Vindo 45 has wide side decks with non-skid surfaces for easy movement forward and aft. It has stainless steel stanchions with double lifelines for safety. It has bow and stern pulpits with navigation lights and flagstaffs. It has an anchor locker at the bow with an electric windlass and a bow roller for anchoring.

Mast and Rigging
The Vindo 45 has a deck-stepped aluminum mast with two sets of spreaders and a jumper strut. It has stainless steel standing rigging with a forestay, a backstay, and upper and lower shrouds. It has a roller furling system for the genoa on the forestay. It has a slab reefing system for the mainsail with two reef points and lazy jacks. It has an aluminum boom with an outhaul and a boom vang. It has running rigging made of polyester rope with halyards, sheets, and control lines.

The Vindo 45 has a sloop rig with a mainsail and a genoa as the standard sail plan. It can also carry a spinnaker or a gennaker for downwind sailing. The reported sail area of 46.2 m² (497 ft²) gives it a sail area-to-displacement ratio of 14.4, which indicates that it is slightly under powered for its size and weight. However, it can still perform well in light to moderate winds and handle heavy weather with ease.

Keel and Rudder
The Vindo 45 has a fin keel with an external lead ballast attached to the bottom of the hull. The fin keel provides good stability and maneuverability, but also increases the draft to 1.6 m (5.25 ft), which limits the access to shallow waters. The Vindo 45 does not have any other keel options, such as shoal draft or lifting keel, that could reduce the draft and increase the versatility of the boat.

The Vindo 45 has a skeg-hung rudder that is attached to the aft end of the keel by a skeg. The skeg-hung rudder provides good protection and strength to the rudder, but also adds some drag and weight to the boat. The Vindo 45 does not have any other rudder options, such as spade rudder or transom-hung rudder, that could improve the performance and responsiveness of the boat.

The Vindo 45 is a beautiful sailing boat that combines traditional craftsmanship with modern design. It is a heavy and stable boat that can handle various sea conditions with ease. It is a comfortable and cozy boat that can accommodate up to six people in two cabins and one head. It is a well-equipped boat that can offer some options and features that enhance its performance and livability. It is a perfect boat for recreational sailors who appreciate quality, style, and comfort.
