Is it safe to solar charge a deep cycle battery in a non vented sailboat compartment?

No. Any charging liberates hydrogen gas; therefore some ventilation is always needed.

Batteries should always be kept in a ventilated compartment. When charging, they can give off hydrogen gas, which is explosive in concentrated amounts. While the charging rate from a solar battery charger is probably not enough to cause serious concerns, it's better to be safe than sorry!

No, it's never safe to charge a lead-acid battery in a non-vented compartment. Lead-acid batteries evolve off Hydrogen gas, which is highly explosive but also easily diluted with air. If the "deep cycle" battery is not lead-acid, such as lithium-ion that does not evolve off Hydrogen) it's probably not a big deal.

But only if the battery has a venting port which you connect to a a tube venting to the outside air.
Where I live an unvented battery compartment will fail mandatory periodic safety checks unless a vent tube has been fitted and can be verified as being functional: the tubes are not maintenance-free as dirt or insects can block them.

NON-VENTED? Battery charging creates hydrogen gas. It could build up in a non-vented compartment. A single spark from static electricity off your body is common around fiberglass boats, so it could potentially ...ummm ... ever heard of the Hindenburg?

Sure - as long as the battery is sealed and the controller does not over-charge the battery.
