I find conflicting information when searching on line, does anyone know the mast height from the deck of a C-25 tall rig and a C-27 Standard rig? My buddy and I are trying to see if I could fly his spinnaker (Which came off a Hobie 33)

standard rig mast 28 feet
tall rig mast 30 feet

on the standard rig, the length of the spinnaker should be 30 feet. The width should be no more than 18. Plus or minus a few inches on the height doesn't matter.

Hi Peter,
Jim's info re: the C25 std and tall mast lengths is correct. A C27 mast length is about five feet longer.
The Hobie 33 spinnaker should measure about 36.5 feet on the leeches and 23 feet for girth. Making the Hobie 33 spinnaker really oversized for a C25 - - and even oversized for a C27 std rig. Maybe ok for a C27 tall rig.

OK thank you. It's a big spin but it works fine on the C-27, we took first place last night in the race in our fleet, all becuase of the "whomper".

With respect, sailboat racing is considered a gentleman's sport, and the participants are expected to self-enforce the rules. If you know a sail is oversized and prohibited by the applicable rules, it should not be used in a race.

Yup--my "keep quiet" part was facetious... The ratings part was not.

All you need to do is declare the sail to the local PHRF committee. You may take a rating hit. I declared my new spin, which is 30 x 18 (old one was 29.5 x 16). No ratings hit for me.

I'm sure he did, I'm just crewing on his boat. He's been racing with the club for 6 years with the same boat. Yes it is PHRF. I know he doesn't take an adjustment for a couple of items so it might have been decided that it comes out "in the wash". I'm sure it's been discussed as he's a straight up guy.

<blockquote id="quote">quote:<hr height="1" noshade id="quote">PHRF ADJUSTMENTS:

Subtract 6 seconds per mile from PHRF# for:

Genoas greater than 155% of J

Spinnaker pole over 100% of J

Operational motor not on board.

Boat with Roller Furling receives a +6 second adjustment.

Boat with Roller Furling and UV cover receives a +12 second adjustment.

Boat with inboard engine and 2-bladed fixed prop receives a +6 second adjustment.

Boat with inboard engine and 3-bladed fixed prop receives a +6 second adjustment.

Non-Spinnaker boat recieves a +6 second adjustment.<hr height="1" noshade id="quote"></blockquote id="quote">

As far as flying it on my boat, that would just be a novelty cruise in light wind.
