I'll ask the questiion here since I assume F18 and Tiger sailors all have to use class legal spin poles. What choice should I make in choosing a spinnaker pole? Aluminum vs. Epoxy/carbon/fibreglass? Pros and Cons? For aluminum, what is the wall thickness used on a 1½" dia. pole? For carbon/epoxy/fibreglass, what % carbon is minimum? wall thickness? Thanks! |

I'll preface this by saying that I haven't run a spin pole on a cat, so experience is limited in that regard. However I do have a good deal of experience with composite & aluminum windsurfing masts and booms. I would tend to lean towards aluminum. The advantages of aluminum over composite for this application: Significantly cheaper, better at handling rivets/point loads, not UV sensitive, overall more durable from a handling standpoint, sufficiently lightweight. Composite tubes need to be babied. Scratches, impacts, and UV damage can seriously reduce the integrity of the tube. The higher the carbon content, the lighter the tube is going to be, but it is potentially more fragile (many good high carbon-content windsurfing masts have a sacrifical glass inner and outer layer to protect the carbon). Carbon/glass hybrid tubes with 30% or lower carbon content are likely to be equal to or heavier than an aluminum equivalent. sm |

Aluminum is all you need on a H18. I bought a pipe with similar dimensions as a Tiger pole. |

I have metal suppliers in my area. what about wall thickness and metal grade? |
