We list here a selection of several hundred but we have data on several thousand different boat classes; many of these have numerous variations that effect a boat's rating/handicap.

If you have other information that could influence the boat's performance then just add it to the Notes section.
The boat's handicap is returned in an email along with all the data you provide, if a 'copy to' address is provided then the email is sent to both addresses. Presenting this email to a race organisor allows your boat's declared configuration to be clearly seen, many check this information for those who are race/prize winners and may penalise if incomplete/incorrect, so better to be safe than sorry ...

A number of race organisors/clubs prefer an email direct from ourselves to assure originality, just enter their email in the 'copy to' field; if you already have a rating/handicap email then just add any changed data plus answer additional questions. Renewal/confirmation emails along with a small contribution get priority treatment.
Clicking on the above 'Send Data' button submits your handicap request to our 'free list', after which, a confirmation page is shown which also provides you with the opportunity to make a donation. Please use PayPal and send several #s each to help us fund this work and to ensure that your request form is prioritised
