New smallish yacht for family

Most all of the all in ones I've seen are unvented. The entire reason to use that size is to save space, and most don't want to waste the space for the vent hose. I've only seen maybe 1 in 10 of those units that were vented.

Like MBevins our 44 Viking has the factory installed Kenmore stackables. We used them quite a bit last summer. The dryer is vented out the side of the boat just like vent fans in heads and galley. They won’t do a large load but not bad and will dry beach towels when needed.
Previous owner had already given up on the central vac and made for more storage space when cruising.
Funny we went with a Shark also.

We have traditional stacked washer and dryer, which is power vented to starboard side. I was skeptical at first but now love the convenience of small loads- esp everyone’s shorts-T-shirt’s, swimsuits & underwear. It washes/drys
Queen sheet sets well and we use to dry/refresh bath towels. I always use the shortest wash cycle and works well.

The stackable apartment sized household units work good. The 1 machine washer/dryer never does.....the vented ones are a little better but still take over 4 hours and generally everything is very very damp when it's finished.

I'd score Combo units not vented as a D-. I know many use them in boats and RV's, but the drying is just too pathetic. Splendide is the most popular brands.

Combo units vented I'd give a C. Small loads and slow drying but better than nothing. While Splendide is the most popular, there were many better, more efficient units. I use the word "were" because I believe several brands have dropped them, brands like LG and Miele.

Properly vented stackable apartment sized units just don't take that much more usable space and work so much better. A-

Full size washer and dryers can also be stacked. Take more space that the smaller stackables. A+.

I'm sure some save, but the majority of the ones I've seen haven't made good use of the space above or below the unit. Perhaps they haven't been representative. Our Sunseeker Manhattan 65 came with a combination unit in the crew cabin area and had plenty of room to stack.

My owners went with a freezer instead of 2 units in the crew stateroom in the 66' Manhattan. We have the dreaded all in one, unvented unit, which thoroughly sucks at drying.

We had both. Plenty of room for both on the 65. I haven't looked at the 66. Things differ on all boats. It was not a choice of freezer or washer and dryer. Refrigeration and freezer space was important to us doing the loop with typically 6 people on board.

They put an unvented unit because there was no way to run the vent unless you went through the engine room bulkhead. Then a freezer on top of the washer...…….I don't see where you'd put a freezer, unless you lost what little crew clothing storage there is......but hey, there's already a 68' Manhattan to replace the 66' which replaced the 65' which replaced the 63' LOL.

And once again, Sunseeker is making minor changes and changing labels and who knows. The 63 and 65 were the same boat except galley location, 66 and 68 newer but the LOA of the 68 is actually 3" less than the 63. Looks interesting.
