Notes

The ALOHA 8.5 is an updated version of the ALOHA 28, introduced in 1983.
The main difference between the 2 boats is the installation of 5 opening port lights down each side of the vessel, and the addition of more brightwork, including a trim piece running horizontally above the port lights. Rig dimensions also varied.
Thanks to 8.5 owner Sean Dubreuil for providing corrections.
