Well, I picked up my 'new' SIB yesterday, an ex-RNLI Y boat.
Overall the condition is very good, just needs a bit of a clean and some TLC.
I'm not sure what to do about the square patches that have been put over the logos and numbers on the sponsons and bow dodger:
1. Leave them as they are. They don't appear to be very tightly attached.
2. Remove and replace with patches that are shaped better (eg rounded ends to match the shape of the underlying orange patch).
3. Remove and clean up underneath with Rib Revive / TFR / sticker remover as per this thread:
Only really an option if there is no trace of the logos / numbers.
Other than that, just looking forward to summer
