Though Merlin Week is not an MROA event, SYC support the MROA. 
The 2019 Merlin Week NOR requires the entrant to be a full or associate MROA member on, inter alia, 1st March 2019. 
 
Clause 2.21 of the NOR says: 

 
Salcombe Yacht Club reserves
the right to forfeit an entry where the entrant is not a full or associate
member of the MROA as at date of entry, draw and 1/3/2019.

 
We will be checking with the MROA on the 2nd March 2019 that everyone on the entry and waiting list, is current. 
 
To avoid mutual disappointment, (meaning you and us) please ensure your MROA membership is up to date in any case and, particularly on the 1st March 2019.
 
Thank you.
