Shipping Dimensions

Posted On:

Most craft are shipped by RoRo (Roll on Roll off) ferry, either on a cradle or a trailer.  These are charged based on volume, with slightly different rates for trailer and cradle.

Larger (and taller) craft or sailing yachts with the rig up, are shipped as deck cargo, typically using a water-to-water service.  This service is normally charged on plan area (ie B x H) and weight.  In most cases a cradle is provided by the shipper.

For smaller craft transported in a container, the rate is per container, subject to weight limits.

Dimensions, Dimensions

Craft are always measured prior to being embarked and the shipping charge will be based on these measurements, rather than those submitted to request a quote.  It is therefore important to both measure accurately prior to quotation and be aware of what can be done to minimise these dimensions.

Please note that whilst Gablemarine may suggest dimensions approximated from data available on the web (eg adverts, owners manuals, sales brochures etc), it is the responsibility of the importer to ensure these dimensions are representative of their craft.  Gablemarine cannot accept responsibility for any increase in shipping charges resulting from inaccurate measurements being submitted at the quotation stage.

RoRo - L x B x H

Imagine a large rectangular box which can be shrunk around the boat (and cradle/trailer) until the extremes are just touching.  The dimensions of this box are your shipping dimensions.  Remember that the height is measured from the floor (or road).  For boats on cradles we normally assume the keel will be 0.20m above the floor.

Water-to-Water - L x B

Looking down from above what is the maximum length and width?  These are your dimensions.

Ways to reduce your dimensions

If you have an outboard or sterndrive, this will/should be raised for transport and may thus extend out further than the boat aft.

If the craft has a radar arch, bimini top, aerials, removable windscreens, seats etc then these should be removed if possible to reduce the height.

If on a cradle and the boat has an anchor then consider removing this as it will reduce the length.

If you have a trailer, the length will include the hitch/neck.


The pictures below show the length and height for the craft pictured.

In the example above we assume the seats can be removed.

Remember to remove the Bimini!

It may be possible (and wise) to remove the radar or indeed the T-top itself.  For Centre Console boats without a T-Top it may well be possible to remove the windscreen to reduce the height.  These engines are not raised which though better for length will not be immune from damage if the boat is loaded with a steep ramp on the ship.
