So armed with the 2-1/2 foot long drill and being very nervous I eyeballed it all again took a deep breath and drilled a third hole through the boat bottom. Success! missed the bolt by 3/4" and dead centre!
So now I can put the deadwood in position drill mounting holes, replace the deadwood and finish the last bit of hull damage.
