I recommend two books
Norries Nautical Tables and the Nautical Alminac. And a pocket scientific calculator.
I can’t comment on Tom Cunclifs Book I’ve never seen it up close. I like Bowditch if you can get a copy second hand it’s a good reference. Not an easy read though. Not popular in the UK. But it is a good complete guide. To date I have not found a better British book.
If you have any questions just ask I will try and answer. Although I have never taken an RYA course. I have heard there is no official RYA method.
The Nautical Alminac has an explanation of two methods.
1 Method using the concise short method tables in the Alminac.
2nd Method using a calculator using the formula used to create the short method tables.
If interested Norries contains a great deal of information. Norries uses the Havesine formula to resolve the triangle via logarithms.
