If a dirty bottom slows you down what do you think it does to your boat

My guess is that the boat was dis-masted at some point and someone bought a used mast from some other type of boat which did normally have a double spreader rig. Double spreaders generally allow narrower genoa sheeting angles and smaller rig deflections while increasing the load on the rig and boat, and complicating tuning.

im on a 30' with one set.... the boats around me are bigger with one set (mostly)... i would take heed of Jeff H's comment that the increased load (esp. on a boat not originally rigged to bear this type of load) could prove problematic, as it seems that the spreaders may bear the load at the cost of yanking out your chainplates that were orig. rigged for diff. load bearing set-up

Jobi—

I would recommend you REMOVE, INSPECT and RE-BED the chain plates. They may be suffering from crevice corrosion and really need to be inspected.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

ive been looking high and low for a 'load calculator' that translates I/J/P/E under sail @ a given wind speed on a boat with a given LOA to pressure on shrouds/chainplates at different points. Anyone know how to figure this? am i thinking of it the wrong way?
thanks

I have tryed to remouve them when epoxying my deck, but these things ar bolted to the boat structure all the way to the hull.

each lateral chainplates ar at least 30in long, the wood on witch they ar bolted is solid with no sings of damage.

the only thing that needed rebeding on this boat was the lifeline posts brackets.

the rear and front chainplates are as solid as it gets, and riggins thick and like new.

one of the 4 laterald chainplates showed water leaking, I took it out epoxyied the wood and all screw holes then monted it back and voila ready to go.
