David Nickerson did a beautiful restoration of pre-Rondar boat #18 

Here are the pictures of upgrade to:-

1. Rudder Post. All owners of Pre-Rondar boats, please check your rudder posts. They are prone to falling off. There is a safety factor, the lack of a rudder can be extremely troublesome in the open ocean. 

2. Forward Footrests. Your forward crew will love you.

3. Gnav. A class requirement from June 2011 forward.

4. Reinforce the pole exit. Nice to have if the cracks appear.

The Class Rules require that all boats have safety lines installed under the gunwale, and the deadline was May for all boats to comply.  That means you have to get it done before NAs next month!  Here is the description to add safety lines to Pre-Rondar boats.  See attached photos as well

The following is answers Christian posted in response to questions.

Can a carbon mast last as long as aluminum masts. Like a 30 year old Ensign mast?

 There are 30 year old carbon masts around. What is required for them to last is that you have to keep UV from breaking down the resin matrix (what you would notice by the resin turning yellow and chalky).

The D ring on my bow snapped off after hitting the dock one day.

I was faced with replacing the D ring, a critical component on a Viper
because it ties off the end of the tack line for the spinnaker and secures
the spinnaker pole from bending too far under stress.

Here's what I found out...

The Tempress hatch doors that come on the side bins of the Pre-Rondar Boats feature a less than stellar design that breaks the plastic hinge pin if the cover is bent back to the deck. One way to avoid rewarding them $40 for this 3rd rate design technology, is to drill a couple holes and run a cord through the slot. It still seals well, and won't break again.
