Yes you can use rope.
Yes you can use rope but you may find, if you go to big with the line, you'll need to replace the mast head sheaves that were sized for wire. Other than that all line halyards are the preferred method these days with NO meat hooks.Before you waste any money at Worst Marine or any of the other big boat stores give Cajun Trading a call. I buy ALL my running rigging from him. His prices and line quality can't be beat. You'll likely pay 50% of what you had budgeted if you priced your rigging at Worst marine. Phil the owner of this site also has decent prices but can't compete with Cajun..Cajun Trading Companyhttp://www.cajuntrading.ca/
