Purchased "Cerulean" Maramu #105 - '82 over 4 years ago, and have been loving every minute on the water. Spent the last 4yrs refitting the interior and creature comforts (she had original cushions and upholstery that needed some TLC). 

I've documented almost all of it on Cerulean's blog:

Check it out - it's been a lot of hard and sometimes extremely frustrating work, but the end result is a vessel that is offshore seaworthy, built much better than newer plastic'hull thickness manufactured boats and has beautiful woodwork, layout + headroom and amenities (I'm over 6'4" tall).

The previous owner did a great job re-powering the year before I purchased her, Eric also made sure the electronics we're updated for normal modern demands (Freedom20) and a few 110v outlets throughout....so I've benefitted a ton from Mr. Lindholm's attention to detail and desire 'to do things right' the first time (thank goodness). 

Added a fresh water toilet to the aft head + plumbing back to the holding tank midship. New water pump and accumulator tank. 

Examples of my posts and how to have fun with documenting the somewhat tedious projects, IMHO focus on Celebrating the touchdowns!
