The irrepressible privateer bounced back again along many major successes. Then in 1628, the Dutch despatched another three large privateer fleets to press home the benefit and hit the Spanish even harder. The smaller Dutch ships had the advantage of speed and manoeuvrability in the heavier Spanish galleons, whose routes were familiar to all or any the privateers. After several battles of varying success, most of the Dutch fleet headed home. The Spanish captains in turn, assuming we were holding now relatively safe, also made a decision to set sail, their ships' bellies filled with Mexican silver. A tighter built home means less outside air infiltrating in the home, which means less oxygen to use for combustion within the furnace. As the furnace burns fuel and oxygen for combustion, it "eats up" surrounding air, which has to be "made up" with fresh air. If air cannot type in the home as easily anymore, this can cause serious issues. As the surrounding air is utilized for combustion, rather than substituted with oxygen, a negative pressure inside the space can happen. This could create combustion problems for the furnace, plus burn up fresh air for anybody inside the home.
