Since I'm currently looking to crew, I have a list of places he could try...
L= $ in Pounds. I can't find the correct key combo.
FindACrew was mentioned above.
Pros: Nice search
engine to enter your criteria; Identity verification
Cons: Not
cheap ($55 USD per month); Limited messaging if you are not an active 'Premium'
member (limited to 'Hi, I'm interested')
I paid for an initial few months, as it seemed the most serious/useful.

CrewSeekers
Cons: Need to pay to contact boats (L75 for 6mo). Cheaper than FindACrew.
https://www.crewseekers.net/
CrewBay
Pros: Free (mostly). Premium is L7 per mo; No messaging restrictions.

SailingNetworks
Pros: Free; Simple searching (maybe too simple?)
https://www.sailingnetworks.com/
CruisersForum
The best ;-)

Pros: Free; Allows PMs, etc...
Cons: Small volume

Facebook Sailboat HitchHikers
Pros: Free
Cons: It's facebook; No search criteria (you have to read them all...)

Sail
Offshore Passage Opportunities (SailOPO)
New to me. I'll check it out...
Pros: Seems serious.
Cons: $199.00 per year to join! Cannot contact boats unless you join.

Maybe we can ask the Mods to make a 'Sticky' post at the top for a frequently updated list of sites... with or without my comments...
Shameless
plug: I am considering
buying a
pocket cruiser. I have lots of sailing experience on my small 17' cat and have done a few offshore cruises (a while ago). Prior to
buying another boat, I want to crew to make sure that's what I want before the commitment (and expense) ;-)
I'm in Montreal, so anywhere on the East Cost is easy to get to. Flying is still permitted.
