for my most recent cruiser, I made a similar paper grid. This was more to identify which boats I wanted to look at more closely. (Once I decided which boats I wanted to look at, I had a list a few pages long of things to inspect.)
Some of the things that I wanted to compare were probably differnet to what you wish compare, so I'd recommend just making your own.
For me some of the things were:
Year, Make, length and location.
type, HP, year, Rebuild
Fridge (yes, no, type, retrofit or original?)
Anchors and Rode
For me things, like whether or not it had a working VHF
were minor enough, they did not affect my decision to look at a boat. Certatinly there were things which are even more important like does it have blisters
, functioning seacocks, condition of sails
, issues with the stuffing box, rigging
that needs to be replaced, etc, but these were issues I'd likely not know until I actually inspected the vessel.
I should also add, before I got to this point, I had already prioritized certain models and knew certain characteristics, such as draft
, sleeping areas, handling characteristics, etc. so that was not part of my grid comparison.
When it came to comparing different models, I didn't really try to analytically offeset the difference, but rather looked more generally at what it would take to get each one cruise
ready, how this compared to a fair market price for that model and what I'd get out of these differences in terms of functionality, enjoyment and resale. I passed on a Morgan
OI, that even after repairs
was much cheaper than the boat I ended up purchasing
. The decisions was due to the erogomic differences, headache factor of upgrades needed, resale and what I was willing to spend.
In the end, for me, it can only be part formula. I calculate what it will cost to address any deficiencies, but then I ask myself:
Do I want to buy boat X with it's needed upgrades and characteristics for price A
or buy boat Z with it's needed upgrades and characterisitcs for price B?
