I had a 1968 36' Columbia sloop I bought the year I retired. I gutted the inside and pulled out all the teak and took down all the hardware topside. After patching holes and rebedding hardware, I repainted topside. I changed all the standing rigging by myself by using a climbing harness and ascenders to go up the mast. That was scary. I resurfaced all the teak and reinstalled below decks and made new teak hand rails for topside. Also fabricated new trim for below decks at the Hickam wood shop. That was fun but very expensive. In Hawaii I was paying $25 per board foot for teak. The learning curve was pretty steep but being retired had nothing but time. I pulled out much of the fancy instrumentation. Broken radar, auto helm, etc. and returned it to the original configuration. I repaired fiberglass down below and painted below decks. Redid the head. Mom taught me how to upholster and I made new cushions for the cabin. Tuned up the diesel, lubed, and changed oil filters and fuel filters. Replaced the sink down below and the hot water heater in the settee. Took off the metal side rails, resurface them, and rebedded them. There were some considerably tight spaces. We had a slip in the military marina right next to Pearl Harbor. That was going to be our "vacation home" in Hawaii. Regrettably, the management at the marina changed the rules for retirees and the requirements became to challenging to comply. So, I ended up selling her to a young sailor interested in sailing. Took a HUGE loss but I believe she will be cared for and appreciated. The remodel experience was tough but satisfying. And she is FAST!!!
