Re: bow railing
My first choice for custom bending would be a boatyard that does metal work. They have the appropriate materials and means to bend the tubing without damaging it or imbedding ferrous particles that will manifest as rust. There are several grades of stainless steel. Some resist corrosion better than others. Dont know the grade used for railing but a boatyard will. There are a lot of aftermarket railing components available. You may not have to have anything custom made, or only just a small piece that curves around the bow.<br /><br />Another option for custom bending of stainless tubing is someone that does hydraulic repair. They need to be able to do repairs onsite, bending high pressure (thick wall) tubing, including stainless steel. They can come to your boat and do custom bending/fitting but Im guessing it is not going to be cheap. Also, Im would be concerned about getting the appropriate grade of stainless steel.<br /><br />You may want to start by looking at aftermarket bow rails. Theres a bunch of them out there. Youll probably get lucky and it will be easier/less expensive than you think.
