do spars and booms ever come with instruction maunals?

[Brian Duff]

manuals for spars are rare, selden is pretty good about providing information, but that probably wont help you.

call a rigger- most should know a ton about Isomat spars, they are on a lot of boats. Most riggers will have lots of time to just talk to you about spars, as we are all boat nerds and get off on knowing about this stuff (were here on a forum afterall) - try Calling Brion Toss Yacht Riggers, 360-385-1080 , they offer perhaps the most informed consultation services you could hope for.

The folks that run rigrite know a ton about boats and rigging, but sometimes Kim has retail sales people that just run partnumbers and credit cards.

Also, check Zephyrwerks.com for better sheaves than Isomat ever sold, at a very resonable price. Ed produces a beautiful and strong sheave that we now use almost exclusivly for replacemets and new contruction of spars , and I bet Brion does too... ?
