rigging question

Hey guys I'm new to sailing got a 20 ft Newport holiday. the older gentleman I got it from never pushed the boat. this last weekend me and some buddies did push it when we were done I took down the mast and noticed I had broke the pop rivets on one side of the mast base. what would cause this and how can I keep it from happening again. We only had 15 to 20 knot winds.

Re: rigging question

What year is the boat? what type of rivets? I would thru bolt it if possible or replace rivets with larger ones to ensure they dont fail underway. Pictures would help.

Re: rigging question

Pics would help, but it sounds like you might be refering to rivets that hold the mast base that sleeves inside the mast section. If that is the case then the rivets should not be bearing any load. The rig tension should create enough compression to keep the mast firmly planted to the deck. If they sheared off it could be a result of ecessive rake or the mast leaning to leeward and trying to "slip off" the base which is presumably pinned to the deck at its pivot point.
Of course this is just speculation based on my experience with my last trailerable boat.
On my boat i drilled out the rivets, and then tapped the holes for machine screws. Through bolting is not necessary.

Re: rigging question

Yes that's exactly what it is. I'm a machinist by trade so I'll have no problem tapping the mast base. The boat is a 19.5 ft Newport holiday. When we had a load on the rig we had three grown men sitting on the high side and sailing close hauled the stay lines on the starboard and the port sides one was tight and one was very loose because of the load is this OK or do I need yo work on this also. Any help appreciated thanks. ( excuse my lack of sailing terms haven't had time to learn them all yet).

Re: rigging question

Typically your upper shouds should be tight enough so that under load the leeward shroud goes a bit slack but not floppy when the rig is loaded up.( A rigger friend of mine said they should go just loose enough that you could pull the pin out.) The lowers are less critical but using the same rule will ensure that the mast stays in column under load.

Re: rigging question

Sorry! Yes shrouds = stays!

You should have turnbuckles or something don't you? I am not familiar with your particular boat but it would be very unusual for a sail boat to have no means of adjusting stay tension. Perhaps if you have some pics?

Re: rigging question

Actually no it dosnt have any the shrouds just attach to the chain plate with a shackle. I knew it was missing something should it have a turn buckle on the forestay also. Thanks for all the info I just want to make this rig right
