[quote=Dogboy]When looking at older 18 hulls, one of the most critical areas to inspect is the hull lip under the crossbar attachment points. This area had a tendency to crack out if not properly reinforced. There is an upgraded crossbar anchor kit available which will strengthen this area and is fairly easy to install. Soft spots in and around the front crossbar area also need to be addressed. Either of these types of damage can result in catastrophic hull failure so be sure to look over any older hulls really well before purchasing.
Also give the front crossbar a real good inspection. The extrusion in the area of the mast step has a tendency to crack over time. The mast step rivets also have a tendency to loosen over time and this can also weaken the crossbar if the rivets aren't replaced. If I bought a used 18, the first thing I would do after inspecting the hulls would be to pull off the front crossbar and give it a real thorough inspection.
In my experience, these are the two main structural areas to focus on when inspecting/refurbishing a H18. The only other thing would be standing rigging. If the previous owner can't tell you the last time the wires and shroud anchor pins were replaced, you'd probably be wise to bite the bullet and replace it all. Cheap insurance.
Good luck with the new boat and enjoy. 18s are a blast.
