I recently purchased a 1998 17 Sport that when rigged, the mast is not perpendicular to the pontoons as I expected based on my previous experience with my Prindle 16. When I looked at the online manuals on the Hobie site, all the masts on the other cats are upright, but not the 17. There is a 3-5 degree rake in the mast, excluding the additional rake that occurs by design at the top of the mast. The previous owner, who was not the original owner, believes the forestay is the original.

When I purchased the boat the rear crossbar was cracked about 270 degrees that I believe came as a result of heavy stress on the boat while sailing, and wonder if the incorrect (?) mast position was the cause?

An answer to either of these questions would be an enormous help:

1) proper mast position (how vertical it should be and stay settings)
2) proper length of forestay.

The angle aft of the mast (Rake) is common to most all cats. Very few would be straight up. The thing to look for on most cats is as much rake as possible. This helps the boat point higher when going up wind. It also helps to keep the bows up so you don't stuff them (pitch pole). The thing that limits mast rake is the distance between the main blocks when fully sheeted. If they touch... move the mast forward. If there is a distance between when fully sheeted... rake more aft.

17 Sport forestay (lower) spec is 17' 2 1/2"

Crack in beam: The 17 was designed as a light single handed sailboat. The crossbars and all parts were built on the light side. The crossbars do have a shorter life expectancy than what we have seen with the 16 and 18.
