Our extensive range of parallel mandrel diameters and the maximum length of each size is detailed in the Parallel Mandrel List. New sizes can be made or existing sizes can be extended to 5200mm maximum length with very low tooling costs if required.
Our Oval mandrel sizes are below, suitable for producing yacht booms, handrails or other items suited to an oval cross section.

Mast Tube Sizes
Our preferred mast base inside diameters are: 40.0mm, 46.0mm, 50.8mm, 56.0mm, 60.3mm, 66.7mm, 70.0mm, 76.2mm, 82.5mm, 85mm and 95mm. All of these mandrels are at least 5000mm long.
We have tapered mast tip mandrels to suit the above diameters plus offset joining spigots to join base and tip tubes with the finished mast having a straight edge to carry the sail track. Other sizes can be designed on request but there may be a tooling cost involved.
Spinnaker and Prod Mandrels
Spinnaker Poles and Prods are often made on parallel mandrels but we have a number of special mandrels with tapered ends as shown below. Prods made on these mandrels are one-piece with the tapered end saving weight and looking neater than parallel tubes. Spinnaker poles made on these mandrels are two-piece, joined in the centre to make 'double ended' poles.
Sizes of the special spinnaker pole mandrels are below, and smaller double-ended poles can also be made using other tapered mandrels in our range.
