Boat (sharing) Co-Ownership with experienced boater? (Reed College Heights)

I am an experienced power boater with boating safety certification and 20 years of boat ownership.
I am seeking someone who owns a power boat who wishes to share in the expenses as well as maintenance that boat ownership entails with an experienced boat partner.
I have a lot of experience from owning boats and can troubleshoot most minor issues plus I know how to detail (with help of course).
I am financially responsible, meticulously clean and a repectful partner.
The ideal boat would be between 18 and 24 feet and between 8-18 years old.
I prefer the handle of a cuddy, but a cruiser or deck boat would be acceptable.
I would prefer to slip it on the Willamette or Columbia.
I am also open to trailering, although I don't have tow capacity.
I have partnered with boaters both when I owned a boat and before I bought my first boat.
The key is responsible partners and mutual trust.
I am a CPA by trade and very responsible/trustworthy.
Sharing is a great way to keep boat expenses manageable.
I am happy to discuss specific details with any seriously interested party.
I am a light boater with minor weekday and weekday use.
This offer is also open to someone looking to buy a boat and would like a partner.
If you are interested, please provide the details of the type of arrangement that would work.
Thank you in advance.
