Have just read Practical Sailor Sept article on the risks of sailing with head sail only. The article raises more questions than answers at least for a novice like me. Two immediate questions that I have are i) how can I tell if I have single or double lower shrouds on my Hunter 430? and ii) what does mast pump mean, what causes it, and how can I tell if my mast is puming?

Some answers
I don't know your Hunter but double lowers mean you have two shrouds on each side of the mast, connected at the spreader, running down to the chainplates. Mast pumping: you know it when you have it. The wind starts blowing enough to make the mast vibrate, then it sorta works up to a "pumping" kinda thing. Basically it makes a pumping kinda noise which can be disconcerting or just plain annoying. USUALLY not much to worry about but you want to make sure your standing rigging is in good condition and is properly tuned (hire a rigger). LaDonna

B&R rig
The H430 has a B&R rig, which is a whole different monster than the conventional rigs being discussed in the article. Conventional rigs on larger boats (over 35 feet) often require running backstays to keep the mast from pumping. A necessary evil. Your rig doesn't need them, and pumping should not be a problem as long as the standing rigging is properly tuned.
