Managing Power On the Seawind 1600 Catamaran | Harbors Unknown Ep. 7
Harbors Unknown
Harbors Unknown is the story of two dreamers, Kristin and Fabio Potenti, and our French Bulldog Yoda. We sold our home at the beginning of the pandemic (May 27th, 2020) and moved aboard our Seawind 1600 catamaran, SV Wanderlust, in September. We’re documenting boat life as live aboard sailors, sharing our learnings, sailing adventures, travel experiences and delicious meals cooked on board. We're sailing SV Wanderlust to Harbors Unknown, to explore the world’s vast cultures through food, a common thread amongst people everywhere. Connecting with people and places through the local cuisine, and showing how those dishes can be cooked on a boat with limited space and resources. We hope to inspire people and showcase the possibility of living an alternative lifestyle living on a boat that provides freedom and fulfillment.

Managing Power On the Seawind 1600 Catamaran | Harbors Unknown Ep. 7
Power! Fighter jets are a perfect example of how much energy is created from fossil fuel especially when the supply is unlimited. But how do you manage power on a boat when the inputs are limited by the sun, wind, batteries and the fuel stored on board? The energy system on the #Seawind1600 is quite complex. #Seawind was very helpful, specifically Shane Grover, in educating us about the different configurations, ultimately helping us decide which system we thought would work best for us.
Shane from Seawind joined us this week to discuss what Seawind takes into consideration when designing the energy system for the Seawind 1600 #catamaran.
The first step in designing the boat’s #energysystem is understanding your onboard consumers and consumption habits in different scenarios (at anchor, passage making, island cruising). What appliances you use and for how long. Things like the microwave, oven, washing machine, air conditioning, etc. The high consumption items we have on board are a washing machine, air conditioning, and a combination microwave oven.
Then you consider the power generating options, like solar panels, the alternators, generator, sea hydrogenerator and wind generator. We have (2) 80 HP #Yanmar engines with the upgraded 120 amp alternator, four 265w solar panels for a total of 1065w + additional MPPT controller, a #FischerPanda 10000i #generator, a 2500w #Mastervolt Inverter/Charger and 150 amp Mastervolt Alternators.
After that you think about the storage options; #AGMbatteries and #lithiumbatteries. We selected the 720AH lithium batteries.
So far we are very happy with our selections, especially the decision to install the lithium batteries instead of AGM.
A huge thanks goes to Shane from Seawind for joining us in this episode!

200 Years of History in Hue
Two hundred years isn’t very old. Especially if you’re Italian. But Hue packed emperors, colonialism, occupation, revolution and war into those two centuries. It’s all about the mileage, not the age .
I Don’t Like the Beach. So I Went to Con Market.
Da Nang is famous for its beaches. I had enough of them. So I went to Con Market instead. Pork, fermented food, coagulated blood, endless stalls, and the kind of organized chaos I was hoping to find in Vietnam.
Alone on a Vietnamese Sleeper Train
I took the train from Saigon to Da Nang. I took the slipper train instead of flying because I was  hoping to talk to some of the locals, it turned out that I was the only one in the compartment.

The Story Kristin Was Telling.
This is the story Kristin was working on before everything changed. We fix what's broken, set sail once more, and follow the route she dreamed of sailing to Lady Musgrave and the Whitsundays.
