Any response will be appriciated. I''m planning to buy my 1st sail boat. A friend want to sell his 1978 Spirit 6.5 for abt. $3,000. It includes a trailer,out board engine and in ready to sail condition. This is a 21ft boat and we plan to use it on the Chesapeake Bay. Mainly for 1-4 days cruising. Most time it will carry 2 people and sometimes 4. Any input regagrding the size, boat quality, price, or better alternatives.
