Thanks for the input guys, I have just ordered a Spektrum DX6 radio for the new boat. I've become really used to the Futaba 3VCS with the Spektrum module and the 'no antenna' look-and-feel. It's especially useful in rain or cold weather because the whole radio goes into the transmitter cover and the...

rudder servo recommendation ?

Hi All, I'll be buying radio components for a new boat in the near future. I've always used plain standard Futaba servos for the rudder. This time I'm thinking of getting something slightly better. Could anyone recommend something from e.g. the Hitec line of digital servos ? A little more speed than...

Hi Steve, I'm not sure I exactly understand what you mean, but if simply measuring from a point somehow defined as stern and bow, then, would it not be fairly easy to build a "rule-braker" by having the boat float with the stern and bow very deep in the water. See attached pic. by "rule-braker" I me...

That sure sounds like a simple solution and is consistent with the manner some other classes use to control draught. However, in this and other discussion there seems to be a lot of concern over doing it that way and a feeling that the hull draught itself needs to be controlled. Not being a designe...

The kicking strap that most of us use (Sails Etc) would, by the same logic (because it is made of metal rather than, say, string), also be capable of working in compression (and hence be illegal)...

Ralph, I'm not sure what you want with this thread. The quote seems to be from one of my earlier posts.

Useful, many thanks! It would be really helpful to know if the method *could* replace the water tank. Do you have any data on how the hulls would have measured if you had no knowledge of their waterline? For example, if you assumed the waterline ran from the transom to, say, 25 mm from the stem?

Hi All,

Olof Ginström came up with a measurement jig during the winter that we tried on about 10 boats last weekend.

We did not try to solve the waterline problem, simply measure hull length, depth, and overall depth _given a known waterline_.
