My 1st boat was a 18' 1950's (?) Lyman with 1926 Johnson seahorse outboard. It was given to me, and I know why. It was a very long narrow boat that cut through the water like butter, fun to putt around in.
It spent summers in the water, but I got it on a trailer. If it sat on the trailer more than a couple of weeks, it leaked like a sieve. A few days before every outing I had to support it on jacks while on the trailer and keep the bottom filled with water. I had to do this for weeks in the spring.
I was told that the best 2 days of owning a Lyman was the day they bought it and the day they sold it. Luckily
I neither bought, nor sold mine. I sold the trailer and the boat was thrown in for free
