Hi FeBR and welcome aboard. Don't worry about the language - we all learn...
"Essential" is very personal. Some would like their
boat to be completely self sustaining and have the comforts of a condominium or apartment. Some just want to get out there at a low cost. These are very personal to you and the limiting factor for almost everyone is
budget.
Where you
cruise can also help define essential. In cold climes where
fog is common and traffic is high some would say a
radar is essential. For solo handers some would say
AIS and traffic alarms are essential. For me not so much.
There are many debates here about what is essential and everyone has differing opinions. I also have decided that a ~40 cat is my
retirement cruising
boat. Comforts for me include -
- Twin engines - no outboards
- Plenty of
electrical supply - Primarily
solar but also generator at times
- Good
refrigeration
- Large
watermaker
- Smaller
air conditioning for at least stateroom for when shore powered or those unbearable still, hot doldrum nights we get near the equator
Nice to have -
- Excellent entertainment system
- Clothes washer
- Very large
head with separate
shower
In terms of maintenance there is a reason
charter companies tend to sell the cats at around 5 years
- Maintenance costs start to go up
- Newer models arrive
- Charterers like new boats
At 5 years you are likely looking at
sails and the engines may have been run a lot. Charters will run the
engine anytime the
wind drops or any time they want
power. This can be good or bad.
Batteries & standing
rigging will start to become a question at 7-10 years depending on where the boat was used.
As far as
interior layout 2 heads vs. 4 etc. This is the big difference between charter cats and owner cats. The other big difference is fitout in terms of
safety gear (life rafts for example), and
electronics.
I think the charter cat has an advantage here. The 5 y/o owner boat will have 5 y/o
electronics technology. It may not be bad but won't be latest. I would rather pay cheaper (charter cat) and add my own electronics.
The owner cat will want to be "paid" for all his upgrades, even though those upgrades are 5 years old. The charter cat won't have the upgrades, should come at a lower
price and you can add your upgrades with the savings with again the advantage that they are
current equipment (new).
