I'm not sure I understand the question. The Heller Victory doesn't come with any life RAFTS. (Please pardon the caps; I can't use italics on this phone.) It does include several BOATS. Many people think any boat carried by a ship is a "lifeboat." Not so. The word "lifeboat" became common in the late nineteenth century, with the rise of big passenger steamships. An eighteenth-century ship of the line carried lots of boats, in several sizes. They had names like barge, pinnace, launch, cutter, jollyboat, etc., depending on design, size, and function.
Plenty of research has been done on the Victory's boats. I don't remember off the top of my head just what her boat complement was, but you can find out in any of the books I recommended earlier. My guess is that she clusually carried six or seven, or maybe more.
One of my criticisms of the Heller kit is the way it handles the boats. They're empty shells, with no detail inside. They should have floorboards, thwarts, oars, and all sorts of other parts. The old Revell and Airfix kits, which are much smaller, actually have better detailed boats.
Unfortunately the aftermarket for such things isn't great. Model Expo and Bluejacket do sell cast metal boats, but they're pretty, well, basic. ME also sells some in "kit" form - precut basswood lifts and strips. The modeler glues the lifts together and carves them to shape, then makes the floorboards, thwarts, etc. out of the strips.
I'm afraid I haven't helped much. Maybe you could get hold of a Revell 1/96 Constitution and steal the boats from it; they probably would look ok, and they're much better than the Heller ones. That's the best suggestion I can offer.
Good luck.
