we have a garhauer rigid vang on our tartan 37. there are hundreds on tartans they are an incredible value at 3-400 dollars including custom boom pad and mast attachment.
i do not see the need for a topping lift as this vang seems to be bulletproof.
we have gone through gales, a storm and 2 hurricanes with this vang and it still looks and works like new.
practical sailor rated it #1
it''s not lightweight but as i said bulletproof.
with respect to the preventer- see bill seiferts book "offfshore passagemaking"
he illistrates a preventer system that we use.
we have lines
running from through bolted pad eyes at the end of each side of the boom to cleats
on the boom near the gooseneck.
each of these lines
has an eye at the gooseneck end.
there is a block mounted at the bow which has a line
running back to the cockpit and a cleat
. the other end has a snap shackle
. to use the preventer you disconnect the line
on the appropriate side of the boom and hook it up to the snap shackle
, then just winch
it in at the cockpit. works great. this set up is endorsed by the marion bermuda safety at sea inspectors.
happy new year.
