Older Hatt vs Older Sea Ray vs Newer Silverton

just buy a Hatt and switch it to 12 or 24 volt, you get the build quality of a hatteras and the electric voltage you want, the wiring is heavy enough to handle the load.

Generally the wiring is heavy enough to go from 32 volt to 24 volt on most Hatteras', but not 12 volt unless you lower loads quite a bit with newer equipment (LED light bulbs, more efficient stuff). But you're also dealing with wiring that is 30 years old at a minimum on a 32 volt Hatteras.

Access to all systems is a high ranking boat criteria in my book too.

The Sundancer (express) models are a bit more difficult because the Aft Stateroom takes up a portion of the engine room space when they shifted the engines back and used v-drives to get this features. They have sold thousands of them, quite a profitable design, but not quite the same installations as on a Convertible/Sedan with the traditional and much larger engine r0om. Here is a view of pumps from a 2004 SR 46 Sundancer:

i did it on my 1972 58 yachtfisherman about 9 years ago. it has passed several surveys and i have not had ANY electrical problems

Yup.... the laws of physics always apply..... even on forums.

LOL..... do you know more exactly WHEN Hatteras started using tinned wire?

I don't, I do know they switched from 32 volts to 24 volts on all of their yachts in 1987. Many years ago I maintained a 1979 58' Yachtfish and I'm pretty sure it had tinned wiring, but the last time I worked on that boat was around 2007.

Yes old post I know, but what ever happened to good old Monel tanks, they last a life time, had them on my 1962 Matthews back when I had her 2001 to 2011...never had a problem with them..why do builders , again try and reinvent the wheel. Is steel/aluminum really that much cheaper. Oh yeah it had the original copper water tank too....still holding water.

A big difference from 1962 to today is the advancement of higher horsepower diesel engines resulting in higher speeds, as well as the desire to travel long distances. The size of fuel tanks have gotten significantly larger, rendering Monel too heavy and expensive for the larger fuel tanks common in todays boats (500 gal +).

Copper lines / tanks for fresh water systems have been priced out due to labor/skill sets necessary to plumb them, seeing much the same in home construction as they just want to build them cheaper as the trades skill sets continue to drop off with the focus on lower wages. There is no better tasting fresh water onboard a vessel than one that uses copper plumbing and stainless tanks, some say it almost tastes 'sweet". Can't get that from the current pvc/pex/frp trend.
