Boat Cradle FAQ’s

Why do Tennamast yacht cradles and boat stand’s use adjustable screw jacks on the hull pads? 

We use adjustable screw jacks on all our yacht cradles and boat supports as it offers very quick and precise adjustment. Any boat should sit in a yacht cradle and not be ‘trapped’. By using screw jacks to give the final fine leg adjustment we can ensure that the boat is sitting in the cradle every time with any shape of hull. The angle and height of the leg can be adjusted independently with the screw jack being adjusted last.  

  Tennamast Yacht Cradles offer; 

  • Maximum strength for the toughest conditions 
  • Minimises serviceable components 
  • Quick and easy to adjust 
  • Easy to achieve the best landing spot for maximum support 
  •  

Many yacht cradles use a turnbuckle arrangement that can be very tiresome to adjust and often result in the hull pad sitting too high on the hull and effectively clamping the boat into the cradle which can put an increased amount of stress on the hull causing distortion which can lead to problems at a later date. 

  

Why is it better to buy a yacht cradle rather than rent? 

Renting a yacht cradle can be very expensive when your boat may be out of the water for up to 6 months of the year.  

  Tennamast Yacht Cradles offer; 

  •   High resale value 
  • Designed for your boat to give maximum support 
  • Quick payback term 
  • Insurance discounts 
  • Peace of mind 

  A galvanised yacht cradle holds a high resale value and can be a very desirable extra if you ever decide to sell your yacht. By making the initial investment you can ensure that your yacht cradle will be available every time you need it, especially if you are unfortunate enough to have the need to get your boat out of the water quickly. You also have the peace of mind that your boat will be stored safely in a yacht cradle that is designed for your specific boat and not just a cradle that your yard/marina has lying around. 

  

Is a steel yacht cradle better than wooden shores? 

Wooden shores are a cheap, quick and easy way of propping up a yacht or motorboat and are still commonly used today but don’t offer the same security that a steel yacht cradle or prop stand can. If during the winter months in high winds your boat moves slightly for any reason it is very easy for a wooden shore to slip and fall leaving your boat vulnerable. As the legs of a steel yacht cradle is a ‘rigid structure’ it will not move if your boat decides to move at all in high winds. Wooden shores are often held in place using wedges which put unnecessary stress on the hull. The surface area of the shore that is in contact with the hull of the boat is much less than the surface area of a cushioned hull pad which spreads the load much more evenly and reduces the amount of force exerted on any one area of the hull.  Many marinas and insurance companies are now insisting on owners using a properly manufactured steel yacht cradle due to increased health and safety requirements and the very low risk of damage to your boat. Some marinas even offer a premium storage location for boats in a steel yacht cradle. 

  

New or Used Yacht Cradles? 

There are many factors that contribute to the perfect yacht cradle for your boat.  

Tennamast have over 30 years of experience when it comes to the most suitable yacht cradle and offer every customer; 

  •   Lifetime aftercare advice 
  • Customisable options 
  • Money back guarantee 
  • The most suitable yacht cradle for your boat every time 

  When we sell a yacht cradle all these factors are considered and you are supplied with the ideal setup for your boat. The main considerations when looking at a second-hand cradle are, the overall length of the boat, number of support pads, width of the cradle which should be at least the size of the widest part of your beam and length of the legs. We see many customers who buy second hand cradles, have their boats hoisted out of the water to discover that the cradle isn’t suitable for their boat. It is then a costly exercise to put the boat back in the water to be lifted back out at a later date. 

  

Can I use Motorboat Prop Stands to support my fin keel yacht? 

While Motorboat Prop Stands will support your yacht, they don’t offer the same amount of protection as a yacht cradle. Again, as with wooden shores if your boat moves for any reason you are relying on an individual stand to keep your boat upright rather than the rigid structure of a yacht cradle. Motorboat prop stands can be used for very short-term support and would ideally be chained together to offer more protection, generally we would only recommend this when the yachts mast is stepped down or the boat is stored short term indoors or in a sheltered location. 

   

Is there a reason that all your yacht cradles are rectangular, I have seen others that are different shapes and with smaller parts? 

Yes, strength, we are based in Scotland and have a massive customer base in the North in some very windy locations where our yacht cradles have stood the test of time. By keeping our yacht cradles rectangular it means that every support is tied together in at least 2 points which maximises its strength, especially from any sideward movement. Some manufactures use small sections of steel that join to build a bigger structure, every join then becomes a weak point and by not using a rectangular base you risk the leg twisting. We don’t compromise on strength as we send yacht cradles to some extreme weather locations. This does mean some of our yacht cradles are heavier in weight which results in the customer getting more for their £. Strong yacht cradles are key to our success. 

  

How do I know what supports I need? 

We have over 30 years of experience in supplying boats supports for boats of all shapes and sizes, take advantage of our experience and give us a call or contact us for our recommendation. 

Generally, we will have a few questions before we make a recommendation. 

  1. Is your boat a yacht or motorboat?
  2. what is the length of your boat?
  3. what is your boats beam?
  4. What is your boats draft?
  5. will you every need to transport the cradle?

Why do we galvanise our products? 

Based 20 minutes from Glasgow, Tennamast are spoiled for choice when it comes to good quality galvanizing with 3 independent galvanizing companies to choose from within a 35-mile radius, this means we can guarantee that our products are always galvanized to the very highest standards. 

  Galvanising is a complex process that offers many years of rust protection and is great value for money when compared to other forms of protection. 

  Galvanising is made up of 3 stages; 

  • Pre-Treatment 
  • Galvanizing 
  • Inspection 

Pre-Treatment 

There are 4 different stages to pre-treatment 

  • Inspection – Yacht cradles/stands need to be inspected to ensure they are safe and suitable to galvanise. Steel is checked for enough vent holes on hollow structures. The steel surface must be checked and be free off paint, grease etc to ensure a good quality finish. 
  • Degreasing – Yacht cradles/stands are dipped in a degreasing liquid that removes any oil contamination. 
  • Pickling – Acid strips the steel surface back to clean base steel. 
  • Fluxing – A flux solution is applied to the yacht cradle/stands to assist with the galvanizing reaction. 

Galvanising 

The yacht cradle/stands are loaded on to jigs and dipped in molten zinc which is around 450 degrees until the temperature of the steel matches the molten zinc.
While being dipped the molten zinc reacts with the surface of the steel to form a series of zinc/iron alloys.
As steel is removed the galvanising tank, the zinc on its surface will begin to solidify. Work is then allowed to cool. 

Inspection 

The newly coated yacht cradles/stands are visually inspected and checked to meet the requirements of EN ISO 1461. Coating thickness is then checked. 

Benefits 

Every part of our yacht cradle or boat stand is galvanised, the steel is even galvanised inside where you can’t see it so you don’t get any nasty surprises like the steel rusting from the inside out without your knowledge until the structure has been weakened too much and you don’t even know about it. 

The galvanised coating is bonded to the steel metallurgically meaning it is unlikely to sustain any damage but to give you piece of mind if it does get damaged for any reason the coating provides a sacrificial protection. If any damage occurs the zinc coating on the steel will sacrifice itself to keep the steel that it is bonded to protected. This protection will continue as long as there is still zinc within proximity as the surrounding zinc has higher electrochemical properties than steel. There is no requirement on galvanised steel to touch up any chips, scrapes or cracks as the coating is self-healing.
