Don't do it
I am currently renovating a 1978 Hunter 33. I have completely replaced all the ports, removed the fuel tank and engine for reconditioning, added a PSS to the shaft, rebuilt the engine compartment, rebuilt the steering system, painted the cabin top and decks, replaced the chain plates and the list goes on. If there is anything I can do to help you during your rebuild let me know. As for the toe rail, I would not, not, not, remove it unless you absolutely must. Is it damaged? While I had all the life line stanchions off, I took a hand side grinder with a cut wheel and cut a shallow continuous line along the toe rail, slightly angled inward towards the toe rail. I used black sikeflex and laid a line of caulk along the toe rail and smoothed it out with my finger. Now I have a very good seal along the deck. Another reason to not remove the toe rail is it is alot of work and getting it back on will be a bear of a job.
