I learned mine in the Boy scouts and the Scout manual will do it. Concentrate on the boline. clove hitch., half hitch, and sheet bend.
When I tought knots, I made scouts practice by feel so they could do them blindfolded. The time your most likely to need a knot is on a dark night.
The power sqadron teaches knots in the seamanship course along with alot of other very useful stuff. Give them a call.
Good luck with the new boat.
