Here are some photos of my friend's Bolger Sharpshooter, on which we built a
"Birdwatcher" style cuddy cabin. It was attached to the inner edges of
the gunwales and utilises the existing deck arrangement. The results have been unbelievably good in practice, and the boat has been very successful in all respects.
Chapter #7 in "30 Odd Boats" by Philip C Bolger features Sharpshooter.
