    Default Hoyt Spinnaker Gun Mount System

    There's a small Freedom parked near me (25 foot, I think) with a gun mount system for the spinnaker pole. Why did this never take off, and asymmetric cruising chutes did? A gun mount system should give be as easy to control and give deeper usage if you believe the arguments put for it.

    A Google search on 'gunmount spinnaker' suggests these are specific to Freedom boats and can only work where there is no forestay. Sort of looks like the asy is a more general usage development from a similar idea but without the ability to use the kite deep.
    If you're not confused, you're probably misinformed

    They can work with a forestay. The pole would fit in front of it
    However, the problem of having both clews fixed can be dangerous
    If a gust hits you cannot release the clew. The option is to release the halliard but release too much & the sail ends up in the water. (Unless the other end is fixed to the downhaul)
    It would take too long to harden the weather sheet & stall the sail
    The sail is not so efficient on a reach as the trailing clew cannot be released allowing adjustment of leech shape
    I seem to recall racing rules that banned having both clews fixed to pole ends at the same time due to i dangers of not being able to release the sail
    This applied to the introduction of twin pole systems which became popular for gybing

    My question was posed because I was browsing an old book, Easier Rigs for Safer Cruising (1986). The author (a junk proponent) says of the Hoyt system: "All that remains now is to trim the pole at the best angle to the wind, using the reins [ie the ropes to the ends of the pole]. There is no need to take these round a winch, since almost all the thrust of the pole is taken by the 'Gun-Mount'. Even in strong winds, it is easy to hold the reins by hand, and alter the trim of the pole at will." p133.

    He makes it sound - and says he had used the system - as easy as a cruising chute.

    I understand that the system was patented, but I presume that it could have been licensed to other builders. It has been used on model yachts, but never heard of it on anything apart from the Freedoms.

    Something like this? I used to crew on one of these.

    No - the Freedom in the yard I'm at me has a short tube affixed to the top of the pulpit. The pole slides along it.

    Here's a video I just found on YouTube: http://www.youtube.com/watch?v=pc1-AsMX8uQ

    and here's one with better camera work:

    I remember that system when it came out. IIRC, I never saw any other boats mentioned with it - I think that Gary Hoyt viewed it as an extra reason to buy a freedom.

    With his Hoyt jib boom, he's gone the other way, and has marketed it across builders.

    Awah!

    I thought it was some cunning arrangement to avoid having the pole and pole downhaul get in the way of the bow chasers when gybing.....

    The 'Alto' dinghy does something broadly similar.
    Several 90's dinghies including the RS400 and Laser 4000 cant the pole to windward about 15 degrees.
    I think something more complex is done on 'mini transat' boats?
