Vanguard Zuma mast / boom specs wanted

Recommended Posts

I picked up a barebones Zuma hull on Craigslist and I'm looking for measurement specs for the mast/boom so that I can start either finding or making replacements.  The only measurement I have is that the mast hole on the deck is 2.5 inches in diameter.  I can't find anything online for the Zuma standard mast height, the boom length, etc.  Does anyone have these measurements?

Here is what I have found so far:

Zuma rigging manual: https://foghmarine.com/zuma.pdf

Zuma specs (not the specs I need though): https://sailboatdata.com/sailboat/zuma

Replacement Sails: https://www.intensitysails.com/zumasail.html AND https://neilprydesails.com/shop/zuma

If I can't find or make a Zuma mast, can I just reuse a Laser, Force 5, Sidewinder or even a Hobie Cat mast?

Thank you for any help!

All the mast and rigging is from a Laser.

It uses a Laser Radial lower section (modified with a cleat) and Laser boom (I forget if it is shortened or not).
Top section as well (with a fairlead).

A few minor modifications done here and there on it, but, it was made, by Vanguard Sailboats, made extensively from their parts bin.

Zum a rigs were made out of the aluminum that didn’t meet our incoming QC for Laser spars.

The Laser Construction Manual specifies the alloy and heat treatment of Laser mast aluminum.  Unfortunately the commercial spec didn’t assure that the mast built from material that met the spec would perform, so we did additional hardness testing of each  shipment of tubes and rejected aluminum which wasn’t in the top half of the specified range of hardness.  We rejected a lot of material, but rather tan scrapping it, we built rigs for Zumas  and Picos out of that material.  These boats are not sailed with the same intensity as the Laser and the customers are not as fanatic about the exact spring rate of their masts.

So to answer your question Laser and Radial tubes work just fine. I don’t have the lengths, but it isn’t all that critical.

Thanks for the responses, I'll keep my eyes out for a laser boom/mast as well.  If needed, I'll use the measurement specs from the ILCA website here: http://www.laserinternational.org/rules-and-regulations/laser-class-rules/measurement-diagrams/

It looks like the Standard and Radial share the same specs for the mast top and the boom, but differ for the mast bottom.  Here are the specs from the ILCA link above:

Both Standard and Radial
Mast Top Section: 3600 mm / 11.81 ft / 11'10"
Boom: 2740 mm / 8.99 ft / 9'0"

Standard
Mast Bottom Section: 2865 mm / 9.40 ft / 9'5"

Radial
Mast Bottom Section: 2262 mm / 7.42 ft / 7'5"

Thank you!

The best feeling a person can experience with a Zuma comes right after dropping it off at the dump.

We had a president with the same name, biggest crook ever, the dump would have been too good for him.
