Re: Sailfish hulls cheap

 

Is there a link to photos of the mod process and implementation?

Change Rudder Angle To A More Vertical Rudder
It was proposed and approved after a long discussion and a year-long evaluation period that a modification of the existing rudder to achieve a more vertical rudder
Add Rule 3.3.3
The Sunfish rudder may be modified by drilling a new pivot point hole and attaching the tiller bolt where the original pivot point was so the angle between the leading edge of the rudder and the centerline bottom of the hull is no less than XXX degrees. The modified rudder shall match the template provided in appendix XX. A skipper may choose to sail with a standard or a modified rudder as long as they do not change during a regatta.
XXX degrees is to be measured and included as part of this rule
Rationale
A more vertical rudder will improve safety by:
? The improved rudder effectiveness across all windspeeds but especially in strong winds
will offer more control and prevent dangerous frequent wipeouts due to the current
rudder’s swept-back design
? A massive reduction in tiller loads will decrease health risks associated with typically
very high tiller loads, especially in strong winds Furthermore:
? A massive reduction in tiller loads will make the boat more appealing to youth, women,
lightweight and master sailors in the class
? It will prevent the common breakage of cheek plates
? Nearly zero implementation cost
? Reduction of scullability will reduce the temptation to engage in this illegal practice
? It will improve the experience of sailing the Sunfish in every condition but especially in
stronger winds. This has been proven by experimentation and the zero-implementation cost makes a welcome change for the class. These benefits can be user-installed without special tools or skills.

The rudder rule change is something I didn't know about - what advantage doe it bring?

The class passed it but don’t drilled a new hole yet can’t use it till world sailing approves it

It would be interesting to see, but I suspect that the position of the mast/rig (fixed) ?in relation to the daggerboard (fixed) would mean that it would be way off-balance. I only have a bit of experience windsurfing but given the way that the steering depends on where the COE (center-of-effort) is, based on tilting forward or aft, I think you'd have some serious problems. I've also noticed that many/most of the windboards have multiple positions for both the rig and the daggerboard..?
I don't know any of this for sure... It might just work! But I have my doubts.?
While we are on the subject: Imagine your (modern) Sunfish rudder. Now take the blade and turn it around in the rudder head so that the trailing edge is now the leading edge. That is what the Sunfish Class has approved for competition.?

Kinda makes you wonder: "do you tell them what they really have", and, having windsurfed a few times in my youth, nowI'm curious as to how well that works on a Sailfish, assuming you used areal sailboard mast, gooseneck, and booms... ?probably more stable than a conventional purpose-built sailboard?

Anyone in Maryland area looking for Sailfish project(s) these are currently listed on CL incorrectly labeled as Windsurfers. (Not my ad, I'm just the messenger :)
Re: cleaning up a minifish that has been in storage

thanks "lewis.kent@..." for the comment about moving the halyard up a bit. i was wondering myself if the placement was/is right. this boat had been rigged with a sunfish sail which was too large. i shortened the spars (piece of cake since there was a join about 18" from the end which was the amount i figured needed to come off) and replaced the sail with a minifish sail. so all the rigging may be off a bit.
Re: Leaks in a Sunfish

 

Lots of detergent in your soapy water. Bucket with a sponge.

Slop it all over. Wait patiently. Have a grease pencil so you can mark the spots that are leaking.

Any Sunfish can be saved ...
Re: Leaks in a Sunfish

 

Our battery powered Porter Cable wet/dry vac works great. Also nice for clean up after sailing.

If you have a shop vac, you might be able to attach the hose to the outlet vent and put the other end of the hose into an inspection port.

And left cockpit vent hole open to not over pressurise

For air pressure, I got a low price 12 volt blower looks like a miniature hair dryer with cone shaped blower nozzle fits tightly in drain hole from Walmart made for inflating camping air mattresses, works perfect

Rinsed off the pollen, evicted a squirrel, shakedown cruise for 1965 Sunfish WAVE and 1984 Sunfish MADISON. We also signed off a new Skipper!


Hope your Spring is near.

Re: cleaning up a minifish that has been in storage

 

Looking at the picture, you might consider tying the halyard farther up the upper spar (gaff). That will bring the tail end of the boom up a bit. She looks like a lot of fun!

We had some Minis for a while but the Skipper liked to run over me with them... :)

Re: cleaning up a minifish that has been in storage

 

Nice work on the Minifish Rolan! And great pictures of damage commonly found inside mast tubes and daggerboard trunks, chipped resin. A simple fix with some fresh thickened epoxy or epoxy putty.
Re: Leaks in a Sunfish

 

I meant to say sail it and then see where the water runs out when she's back ashore :) That's how we found a leak on one of our boats. She had a soft spot on the keel that we didn't notice, trailer roller damage. We fixed? that up with some MarineTex epoxy putty.

Re: Leaks in a Sunfish

 

Speaking of the hole on the forward wall of the cockpit, that is indeed a vent hole, it keeps the pontoon hull from overpressurizing on a warm day, which could pop a seam and/or detach the foam block inside. Don't plug it up (except for a leak test). Also don't let the cockpit fill with water while boat is in storage, water will get into the hull and soak into the foam.

Check along the metal edge trim real well, especially up front where folks ram docks.

You're welcome. Have fun playing with bubbles.

AIr leak test.






That is our youtube page, use the search icon magnifying glass and search for "air leak"

Common spots for leaks are the daggerboard trunk, bailer seam and chine. Topside you might have water getting in through mast step, your can pour a cup of water in there and see if it disappears. Another common leak area is the seam on the older Sunfish with the metal trim.

Use low volume, low pressure air. Too much pressure can pop the seam or balloon the hull and detach the blocks. Soapy water in a spray bottle.

There are 33 plus designed holes in the Sunfish, plus the seam. Good luck!!
