Gift for man who likes sailing?

[Cathpot]

DH refuses to suggest Christmas gift ideas.
I am out of ideas and fed up of thinking about it - so posting for help.

Hobby is sailing . He has all the usual wet weather kit although he does need a decent warm hat to stop him stealing my (pink) one.

Any thoughts? Yacht not dingy sailing, occasional overnights in winter, more regular in summer. Doesn’t drink hot drinks so flasks etc are out.

Doesn't have to be a big item- just something he would get use out of, practical is good, compact is good, Budget around £50?

One year I got my dad a beanie with a light in it for when he was doing work on the boat. Last few years I've done a sailing magazine subscription which he likes. Have done new cushions for berths for big birthday.

Thank you-good ideas , and actually the light in hat I got for my dad (also sailor) last Christmas. I don’t know if DH would read a magazine- he doesn’t generally , but it’s a good idea for my dad, so that’s a different issue solved!
