I pay $125/month for 24-foot wide slip. I don't need deep water, like a mono, so it is actually considerably cheaper than a mono of the same length. The marina has many wide slips and a lot of multihulls.Try to find a marina that accepts multihulls. Given that coastal cruisers spend 90% of their lives tied to the dock, if there isn't anywhere to the your boat up you aren't going to buy it. Those marinas that do accept multis have limited space for them
You need to think declarative statements through.
