Trojan encapsulated stringers.

[BeaconMarineBob]

Here is a picture of a encapsulated fir stinger on a F-32

All Trojan F-Boats, Trojan Internationals have encapsulated stringers.

Except the 5 different 10 meter International models the International 9 meter express and Trojan American which do not have encapsulated stringers and are a liner boat construction.

( The 10 mid cabin express DOES have stringers and should not be confused with the 10 meter express)

The last 2 years of the 10.8 express 1990-1992 was changed to a liner boat.

Encapsulated stringers is a common boat constructed with fir or laminated plywood as the core of the stringer.
