With reference to the Byron Class Number (ByCN) sailboat handicaps: if you would like to send data to help improve our knowledge base (as more/better data can amend a Class Number) or to get a specific boat rating (ByPN) then just complete and send the following form. It's basically a free service but if you want a priority response then a donation is required.

Our ByCN website listings include a selection of twelve hundred plus boats, but we have data on several thousand different boat classes; many of these have numerous variations that effect a boat's handicap/rating.

Don't be 'put off' by all the questions!

We probably know most of the main detail already, but if you have other information that could influence the boat's performance, that is not covered by the form fields, then just add it to the Notes section.

It's often just the options/differences from the base class that we need to be told.

Clicking on the following 'Send Request' button submits the form to our free list, after we receive the data a confirmation page is shown which also provides the opportunity to make a donation to help us fund this work and to ensure that your request is prioritised.
