Buy OSRS Ironwood hull parts
Ironwood hull parts are an item in Old School RuneScape. Players use them to build an ironwood hull on a skiff. They can also turn them into large ironwood hull parts, which are used to build an ironwood hull on a sloop.
To make ironwood hull parts, a player needs level 77 Construction and a shipwrights' workbench. Each set of parts uses 5 ironwood planks and gives 437.5 Construction experience. A skiff hull needs 10 ironwood hull parts, so a full hull takes 50 ironwood planks in total. Building the skiff hull needs level 81 Construction, plus 300 rune nails, 20 swamp tar, and 5 cupronickel bars.
Making large ironwood hull parts also needs level 77 Construction. Each one uses 5 ironwood hull parts. A sloop hull needs 16 large parts, which adds up to 400 ironwood planks overall.
Ironwood hull parts are tradeable and noteable. They are not stackable and cannot be equipped. Each one weighs 4 kg. Buying these parts saves time for players who want to build ship hulls and train Construction without making every plank themselves.
