With the price of stainless steel nowdays and labour, its worth seriously considering these

They were about $160-170 each, so stainless would be not much different I would think

I also got my rudder shafts and tubes from them. Very good close tolerance fit.



They also make tapered tubing of various sizes and thicknesses - we got some 750mm glass staunchions for our lifelines, immensely strong and mounted onto a solid fibreglass rod "stud" glassed into the boat, there is no chance of leaks, or screws coming loose.



At $32.55 each for the staunchions, compared to Ronstan ss ones at around $70 a pop plus $30 odd for the bases, plus screws, nuts, washers, backing plates.......

For the purposes of the excercise, Perry Catamarans use a 60mm rudder tube with a 6mm wall thickness on their cats which are built to survey. Excel supplied me with the same tubes (material) but in a 50mm diameter with 6mm wall as my cat is only 31 Ft and rudders are significantly smaller.

The staunchions we got are 780mm high, 33mm base dia, 25mm top dia and 4mm wall thickness. We also got some 25mm solid glass rod which (after a bit of grinding) fits inside the the staunchions. Cut the rod into 300mm lengths, which go through the deck 150mm and are glassed on inside the boat, the staunchion is glued on to these. It ends up extremely strong with no chance of leaking.



BTW I have the same spec rudder shafts as Perry - I guess I can sell my boat for a million bucks too when it's finished!
