1994 Renken deck boat 22' - 115 Yamaha<br />I want to store boat on davits. The stern<br />has two rings through transom looks strong. <br />Bow has tow ring only.<br />By using a lift ring adapter kit - will the<br />tow ring be strong enough to hold bow weight ?<br /><br />Or will I need a sling ?<br />Factory help unavailable - out of business.
