Each rack is made up of the following parts;

Bases – there are 2 types, one each for single sided and for double sided racks. Uprights – there is one design, but with 4 choices of height. They are all made with a series of holes (vertically, every 50mm), so that the arms can be attached (with bolts), at different heights, so that you can chose the best position for your needs. Cross stays – there is one design, but with 3 choices of length (span). Connectors – only used with double sided racks, to connect pairs of uprights. Arms – there are two types; One is a simple 700mm long square pipe (50mm x 50mm) that has been welded to a steel back plate, and has an extruded rubber top to protect your boats. The other type also uses a 700mm long square pipe (50mm x 50mm), but the steel back plate is longer, and there is a steel pipe gusset from the bottom of the base plate to the middle of the arm, to provide reinforcing.This arm can be used like this (the extruded rubber top needs to be ordered separately, as it is not included in the price), or you can add a sliding outer piece.

For small boats (1s and 2s), it is usual to support boats with just 2 arms. For this, the ideal span is 2.8m. For 4s there is a choice of either 2 or 3 arms to support each boat. For 2 arms, you may choose a span of either 4.2m, or 5.6m. For 3 arms, you will need to have a double span of 2.8m. For 8s it is usual to support boats with 3 arms. For this, the usual span is 5.6m, which is doubled to 11.2m.

For single sided racks 3 cross stays will be needed, unless you have chosen to use 3 arms to support each boat, in which case you will need 6 cross stays. For double sided racks 4 cross stays will be needed, unless you have chosen to use 3 arms to support each boat, in which case you will need 8 cross stays. For single sided racks 2 uprights will be needed, unless you have chosen to use 3 arms to support each boat, in which case you will need 3 uprights. For double sided racks 4 uprights will be needed, unless you have chosen to use 3 arms to support each boat, in which case you will need 6 uprights.

If you want to be able to move your rack around, you can attach wheels to the bases, 2 wheels for each base.

There are 2 types of wheels;
