I bought a 105ah Deep Cycle AGM battery, volt meter & switch(to check condition), along with a 50 amp manual breaker-wire-connectors for the outboard wiring.
I bought a 15amp 'smart' battery charger too!
And I took a few photos...
I bought a great classic! The first year Catalina introduced the Capri 18. And this one has a history too. Captain Shane St. Claire sailed from California to Hawaii in 28 days back in 1987! It needs a total refit, which I'll enjoy doing and then sail inter-island here in Hawaii when ready!
