We make sure to tie up in a marina from Friday midday to Sunday morning. We’ll be connected up to shore power which means we can have air conditioning on the boat.. dinner will be hot but we will usually have a cold lunch. Everyone is invited to be together and eat meals together on shabbat but you are free to go off and wander around the town or do you own thing.
Lights are left on over shabbat where they are needed and the water system, although operated by pumps, is a delayed passive system which we can explain so you can decide if you wish to use them. Toilets are usually operated with a manual pump mechanism.
Should you feel more comfortable in a room off the boat for shabbat, you are welcome to go to a hotel or AirBNB nearby.
