What is the purpose of the hull liner in the CP 19

[CptFrank]

I have an older CP 19 without the hull liner.
What is the purpose of the hull liner?  Is there a disadvantage or problem not having one?

Sorry confused. What is a 'Hull Liner' I have no 'hull', liner but I do have a fiberglass cabin 'roof top and sides' down to the cabin-deck/hull joint. Is that what we are talking about?
Any liner within my hull is carpeting glued up the side, again up to that deck/hull joint embellished with a few teak strips.

I'll guess you are talking about the liner inside of the cabin.  Those are only on the XL's which represents the last few model years and a small amount of total boats.   There is no other liner that i'm aware of.

As skip aludes to, it's basically cosmetic. Looks cleaner and more finished inside.  Is it important for structural reasons or sailing characteristics..no not at all. In fact it may actually slow the boat down-it's probably a little heavier than the standard trim on earlier CP19's.

The only real advantages I see are a little more sitting headroom (not up, but back towards the hull) and less teak inside to maintain.
OK, and it looks pretty darn good!  Possibly better insulation too, but that is only a guess.

Disadvantages--I have no clue how I would bed in a piece of hardware under the liner to not allow the bolt heads to pop through the liner.  Towards the hull/deck joint there is room for fasteners, but aside from that...you would have to drill all the way through.  Which by the way is how the handrails and hatch slides are installed.  I don't recall if my halyard winch bolts all the way through the liner or not (just got the boat recently and now it's in storage).

One of the up grades over the years to CP16 was a hull liner....I installed one in my boat.....no more condensation on inside of hull, quieter, provides finished look.....the liner I glued to the inside was a thick carpet type material........Phil

The Com-Pac 19 XL [my hull # is 588 of the entire 19 family and is a 1996] has a fiberglass insert inside the cabin and these XL's can be identified easily from the dock by simply looking at the four 4" dia port holes as the XL's will 'stick out' further then the older non-XL's having a fine teak plywood surround in the cabin. The wood is about 1/2" thick and 'pulls' the port inboard that much, till almost flush with the cabin.

Don't know when that XL business started, nor when the hull colors, rigging, and bow sprit was added or changed for that matter.

Caution!!! This fiberglass insert is very close to the inside of the cabin's fiberglass. As close as touching to 3/16" and so when drilling a small hole for screwing in and hanging an auxiliary lamp or barometer...

[see my Frappr pictures with link below]...

A accidental hole can go clean through the entire cabin structure to the weather side, necessitating a repair to the fiberglass cabin.

What this fiberglass insert does is;
1~Gives a wee bit more interior room.
2~Brightens the interior as the insert is white, not a dark warm wood glow. I painted the inside of the sliding hatch and drop boards gloss white to match the insert...

[the drop boards I cut in half horizontial on a 45 degree so water won't drip in and allows great storage of the two halves and provides a lower or upper closeure to the hatch. With a boom tent this adds privacy but allows air to circulate around.]


3~Reduces manufacturing costs and labor costs.
4~Probably adds a couple of pounds to the boat's over all weight.
5~Is pleasing to the eye with it's fluted 'imitation planking' fore and aft design.
6~The insert makes it very tricky to add a bow sprit, stanchions, or bow pulpits as it covers the deck/hull seam...

[For stauntions I had to super glue the washer and nyloc nut to my finger and have someone topside turn the screw to get that started and then make a special goose-neck wrench to hold the nut when tightening down. Oh and a UHMW pad was placed under the stauntions with copious amounts of 3-M 5200 slow set. The factory plywood hard points were there fiberglassed in and I just drilled through these as well as using UHMW pads top side...]

7~Other then that no other changes to the rig, bow sprit, sail plan that I could ascertain.
