FPB 64 Hinged Masts

Over the last couple of years we have had numerous questions about the FPB 64’s hinged mast system. This is a costly exercise compared to a fixed rig.

The hinge itself looks simple enough. But by the time you do the engineering, execute the weldments, and make the necessary wiring allowances, there is a considerable investment. […]

Anchor Snubber Lines

Anchor snubber lines, shock absorbers in reality, offer a number of benefits and several potential problems. Let’s address the rigging first.

The ideal snubber will be made from a stretchy material (we favor three strand nylon), and long enough to provide plenty of give as the loads come on.

Musical Propellers and How To Tune Them (out)

We usually specify what is called an anti-singing edge on our props. Essentially this is a chamfer on the forward face trailing edge of the blades as shown above. Occasionally this is not quite the right shape and at certain RPMs and loadings the prop will start a high pitched, and very annoying, song.

The props […]

Protecting Your Wireless Internet Communications

Pete Rossin, on of our FPB 64 owners, has researched protecting wireless Internet communications in the age of “Firesheep”. Pete has been kind enough to share the approach he has adopted, including screen shots, to make a similar installation relatively painless.
 

We have put Pete’s comments into a PDF file which can be downloaded here. We […]
