Under each heading there are several options to choose from.   The first option is always the standard option.  This is the system presently most favoured by top competitors.   If you are new to the class this is the best possible starting point. 

Subsequent options are for alternative systems that are commonly used.  Over the years we have fitted 470s with almost every system imaginable.  We have refined and developed these to the point that they are the most functional and effective systems possible.   Check the view links to see system photos and drawings.

We would strongly recommend that any 470 crew keeps their layout within the parameters listed below.  However,  please feel free to make any comments in the space provided.  We can make changes to suit custom requirements if necessary.   With good communication and by sending us photos and drawings we will ensure that your layout is exactly as required. 

Only the best fittings possible are used and we select different brands for different functions depending on factors such as strength, weight, durability, reliability and operation.   For example, we use all Harken blocks except for high load applications where we use Ronstan.  We use Ronstan small cam cleats, but Harken big cleats.  We also use some Fredrickson, Holt and Riley fittings.   We will however,  use a different combination of fittings if required.
