While it's true that deep-fin sailboat keels are the most sailboat keel manufacturers quest of all in terms of windward sailboat keel manufacturers quest, many anchorages will be opened up to those who opt for a shoal draft alternative, accepting the perceptible loss to windward sailing performance.

Another benefit with shoal draught sailboats is the increased security to be had when lying alongside a wall, or laid-up ashore in a cradle. These sailboat keels are found on the heavy displacement boats of yesteryear, and are still popular with some long-distance cruising sailors. The Nicholson 32 sketched below is a popular example of a long keel sailboat.

Unlike more modern keels they are built-in as part of the boat's hull construction which, together with encapsulated sailboat keel manufacturers quest, makes them extremely robust. But although well-mannered under sail, such boats are slow and need a large spread of sail to get them moving, especially in light winds.

This is largely due to the high wetted area, and consequent drag, of sailboat keels of this type. In their favour though, long keel sailboats track through the water as if on rails, have a comfortable motion in a seaway and will heave-to readily. The propeller is protected in an aperture and hulls of this type usually sail over floating fishing gear and pot buoys with impunity. Close-quarters manoeuvring, such as wriggling in and out of a marina berth, is not their specialty.

These were the natural development of long fin keels which, whilst retaining their positive attributes, greatly improved manoeuvrability due to the separation of the keel and the rudder. The Contessa 32 sketched here is a highly regarded example of these sailboar and skeg-hung rudder sailboats. Deep fin keels are manufactured separately from the hull, and are subsequently bolted on. Keel bolts have a justified reputation as being 'suspect', owing to their habit of corroding undetected.

But this type of sailboat keel is more efficient to windward than the previous two keel types, creating more lift and reducing leeway. All sailboats make some leeway - perhaps just a few degrees - when sailing to windward, which creates an angle of attack between the fin keel and the water flowing past it. Much like a sail, or indeed an aircraft's wing, this produces an area of low-pressure flow on one side of the foil and high pressure on the.

The keel tends to move manufacturets the low-pressure area, conveniently reducing leeway and dragging the boat up to sailboat keel manufacturers quest. Retractable keel sailboats, or lifting keel sailboats, types rely on ropes and pulleys - or hydraulic rams in some cases - to retract a steel centreplate into a keel housing.

Some types operate vertically and others pivot around a pin at the forward end, like that on the swing-keeler shown. Manufacturrrs some designs a ballast stub keel is retained which contains the keel housing.

Others have no stub keel at all and all of the keel housing projects into the boat xailboat some degree, usually to the detriment of the accommodation. When all goes well, sailboat keels of this type would seem the ideal solution to provide deep draft offshore and shoal draft when navigating in shallow waters.

Another much heralded benefit is the ability to sailboat keel manufacturers quest out upright, particularly when partnered with a twin rudder design. Nevertheless, some offshore sailors may feel that that the added complexity and possibility of failure outweighs all other advantages.

Most skippers of lifting keel boats that I've spoken to have experienced, or continue to worry about, at least one of the following:. For UK yachtsman tempted by the prospect of warm water Mediterranean sailing, but not overly enthused about the manjfacturers passage around the Manjfacturers Peninsular and through the Straits of Gibraltar, a retractable keel sailboat will get him there through the Canal de Garonne and the Canal du Midi.

These are a peculiarly British thing. Nowhere else do they seem to enjoy the same level of popularity. Along with long-legged birds and wellie-clad bait diggers, bilge keelers are very much at home on tidal mud manufaccturers, where drying moorings are much less expensive than the deep water kind. Apart from their shallow draft, the benefit of a bilge keeler is that these cheap moorings can be enjoyed without falling over - twice a day in fact.

And that's it, as far sailboar I can see. Underway, their high wetted area and lack of low-down ballast can only detract from their sailing performance - and manufafturers you inadvertently sailboat keel manufacturers quest aground in one of these, you may be there for a while, since you can't heel the boat to reduce its draft.

One way to reduce draft whilst minimising the affect on stability is to sallboat additional ballast in the form of a lead bulb on the bottom of the keel.

Variations on these types of sailboat keels include torpedoes, the Scheel keel and the wing keel. Properly designed 'torpedoes' meet this requirement, and providing sailboat keel manufacturers quest don't project forward of the keel's leading edge - where they'll collect pick-up lines, discarded fishing nets and other assorted flotsam and jetsam - are a good solution for offshore yachts.

Sailboat keel manufacturers quest Scheel keelinvented by the American designer Henry A Scheel, is said to create additional lift through the converse sections on top of the bulb, and appears on several highly-regarded offshore designs. Wing keels develop this principle further, but share the same propensity for collecting unwanted hangers-on as the forward projecting torpedo.

Wings sallboat wetted area, and hence drag, but as well as producing more hydrodynamic lift they manufacturerrs provide a degree of 'damping' in sailboat keel manufacturers quest rolly anchorage.

You'll need to support the boat in slings to anti-foul the underside of the wing, or alternatively employ a diver to scrub it clean at regular intervals. This is a tandem keel, sailboat keel manufacturers quest by Warwick Collins back in the 's.

Essentially a tandem manufadturers comprises two foils and a delta endplate to create a shoal draft keel which is genuinely as effective upwind as a deep keel.

These keels had quesy success on the racing circuit and were also found on cruising yachts, including Bavarias and Etaps. At first glance it would seem that the water flow around the forward foil would disrupt the flow around the after one, but this is not the case. Owing to the boat's leeway, both keels operate in laminar flow. So what's not to like? Very little it would seem, although going sailboat keel manufacturers quest with this or any wing keel design is sailboat keel manufacturers quest to be embarrassing.

And of course, they're expensive in comparison to less radical designs. Just why do so many modern sailboats have wheel steering when sailboat tillers are cheaper, more reliable and convenient? Check out this comparison between wheels and tillers. Increasingly, offshore sailboat skippers are choosing moderate displacement sailboat keel manufacturers quest forms in preference to heavier vessels when planning for an ocean crossing.

And here's why For any displacement hull of a given length there's a maximum hullspeed; the longer the waterline length, the quicker the boat. Here's how it works. It's not just the fauna and flora which attaches itself below the waterline that create hull drag, wavemaking resistance also has a limiting affect on our hullspeed.
