This image was sent to me by Justin Cetas of his Jollyboat in Canada.

More info as soon as I have it

These days most Jollyboats are using aluminum masts and stiff ones at that. But it wasn’t always that way, for a while the ‘wooden-tops’ were common in the fleet, but the earliest boats had wooden masts. Wonderful examples of wood-work. Amazingly light, there was not much weight advantage to going to an ali mast. They were made from two halves, some parts as thin as 1/4in. J3 still has its original mast, but is normally sailed with a Needlespar.

Unknown number or location.
