I am also thinking about buying a tanzer 25 ft 1978 model.
I have never owned a boat but took lessons.
A smart move
Is this a safe bet for two women to buy and sail on a llong lake in Canada?
Yes - which lake ?
Is it stable and roomy enough to sleep on ?
What size motor do you need ?
I think that a 5 or 7.5 hp would be good. Make sure that the motor mount is strongly attached to the boat - particularly if you get a 4 stroke engine.
Do you need to have mechanical skills or carpentry skills to own a boat this old? any advice is appreciated.
You need basic mechanical and carpentry skills to own any boat regardless of the size or age.
Is $14K a good price without a trailor?
It depends. If you are really looking at a Tanzer 25, then it is not as old as you stated. They were not built before 1986. $14,000.00 is acceptable for that boat IF it is in very good condition.
It is more likely that you are looking at a Tanzer 7.5. (The 7.5 indicates that the boat is 7.5 metres long.) They date from the 70's and you can find one in good shape for about $7,500.00. Do not pay $14,000.00 for that boat unless the owner has replaced pretty well everything recently and can back this up with receipts.
To determine exactly what boat it is that you are looking at, go to this website: Tanzer Industries Ltd. Yacht Builder
When you have finished there go to the following website. There is a section there called the VALUGUIDE. This will give you actual Canadian asking prices of various models and years of boats. It is a valuable resource.
