Re: Bow Foam: Is it necessary
iplayfarmer,
First, the caveat: I am not personally familiar with the craft you are speaking about (1953 17' Hydroswift). However . . .
There are numerous areas on the internet to determine what the [current] standards are for the manufacturing of watercraft to meets applicable USCG Standards and be considered NMMA Certified.
Try typing "watercraft floatation certification" in the search engine of your choice (Google is where I typically start) and you should provided with a long list of links to review and help inform yourself on this subject.
So not knowing if the boat is lapstrake, ply, or other product of common use in that period of boat building, it sounds like a previous owner was trying to create his own flotation improvements. Keep in mind your boat is effectively grandfathered and are not "required" by our Uncle to alter or improve it to todays standards. It would be just from a personal choice it you want to leave it or improve upon it.
How much does it weigh? What engine is powering it and what is its weight?
You likely do not have a significant amount of space under the gunnels to add something or have sufficient access under the deck so the bow area was where that other owner tried to increase the saftey of the boat (btw, what is the condition of the hull of the boat; thats a pretty old vintage and if it wasn't properly taken care of, well who knows; I will stop speculating :redface:
Don't know if this answered your question specifically; there are just too many variables that were not addressed in your question for anyone to answer specifically. Good luck on the web search.
