yeah ive seen those portable aircon units, i looked at a 1350w 12,000btu unit, which evapourated the water
on the hot air coil and had a vent like a tumble drier so you just put the hot air tube out a window, couple a small 2kw portable generator with a shore power
adapter and away you go, charge batteries, heat hot water
tank and cool interior
in one go and very cheaply compaired to anythign marine
, granted id not expect a huge life span out of them, but hey a couple of years of an hour a day use i think theyd last and cost would only be 400 quid.
Another thought is the lwl on the 46 cruiser its 40 foot but on the 50 vision it is 49,9 making 1.5 mile an hour hull speed
difference, which is a fair amount on a longer passage
As for extra toys meaning more systems meaning more chance of something going wrong im well aware of this, though i think electronics
wise if it doesnt break in the first 6 months it will last a long time. something simmilar with mechanical devices as well, but again they are prone to ware with use. Though i cant see that many systems failure occuring on a 3 years old boat, yeah maybe once they get to ten years old things will start to break at a fairly alarming rate.
Myself personally i dont think i could be a slave to the toys, if the gen went down **** just buy a cheapo 200 buck land based one, then sort it out when youve got nothing better to do or can have it done cheaply same with aircon.
I did mechanical electronics at uni, or mechatronics as they called it and a lot of amatuer car mechanics when younger, ie no money so you either fix it yourself or dont have it, no option to pay someone else to do it, so to be honest most repairs
i could do myself, when i could be bothered that is
Pros n cons time...
Big boat -
pros faster, more space,far more toys, better motion , safer in a blow. greater load carrying ability, though only a small pro as a 46 should carry all i would need anyways.
cons more expense (fuel, marinas
, lift/antifoul) i will ignore rigging
due to age,more toys that could break, greater initial cost, but greater resale value. more toys that require upkeep.
pros - cheaper (fuel,marinas, lift
antifoul) , less toys to go wrong, cheaper initial outlay
cons - less space, slower, poorer motion, less safe in a blow, less toys.less load carrying ability, probably more motion at anchor
