trailer sailer + bottom paint

[beernd]

I am sure this question has already been raised, but have mercy on an internet kluts.

I am building a 25'raised deck cruiser, I cros plank her with two layers of 9 mm Larch.
This boat is going to be the first of a small rental fleet of trailer sailed boats.

Do I need bottom paint, or is there better way to treat the bottom of a boat thats going to be trailer sailed.

Cheers

And the question is ??????

Were we to assume a connection between the thread title and the question, since there is no connection between the thread title and the content, then we can answer that a boat that's trailored does not need bottom paint, even if cruised for short periods like a weekend or even a week.

Sorry about the mess, but either Google, or my internet provider, is playing a devilish game of " Pester a Poster"
I managed to complete the first post now.

So I don't need bottom paint.
Could you recomend a paint ( or epoxy) system that would be the right thing to do for a trailer sailer?

No recommendation since I don't know fully the construction or the level of finish. If this is going to work in the long run as a rental fleet, then likely you want a durable, repairable paint scheme and a workboat level of finish. No varnish.

I'll further assume that despite the cross-plank bottom, the construction is suitable for dry-sailing. That is, not caulked seams and not in need of swelling up to stop leaking and to not have the rigging strains work the fastenings. I'll hope these thoughts mean something to you that you've already answered.

Given those assumptions, I'd go through the expense of sealing all the wood with CPES. Inside and out. This is a nudge pricy but well worth it for boats that can be expected to get some hard use.

As for the top paint - you'll be needing to repaint annually and perhaps patch-paint time to time so I recommend a really good exterior latex, maybe a pourch paint though I've found regular exterior just fine. Use non- or semi-gloss white for the hull inside and out and then use pleasingly calm light colours for accent trim. Can't go far wrong with a soft beige or pinkish for the decks and harmonize a little contrast for seats. Make them all different.

Latex on a boat does not hold a good look longer than a couple of years but it's so cheap and so easy to prep and apply that it's in the end cost effective for this sort of business.

Have fun.

I forgot to say that the crosplanks will be glued together with epoxy.

Are we talking complete fiberglass/epoxy encapsulation? If so I can recommend some things. I trailer sail but the boat is sheathed in fiberglass/epoxy.

I would like to do without fiberglass, just a few coats of epoxy.

IMO use a one part epoxy primer and paint system (i would sheath the bottom so its not taking that much abuse) systems three is spendy but better when priced out than most others. International is good stuff and a two part, it works great. make sure you have a primer and paint the work together. three coats of paint with a light sanding between coats or if you are good the epoxy chemical bond is best. However this means no drips runs holidays etc. then when those three are on and sanded (the first three need to cure till hard) a final light sanding and a final thinned coat (follow the instructions) then if you want a really durable finish a clear coat of a good fiberglass wax. this will keep the bottom looking nice and make a good durable bottom that will only need touching up if you get chips and dings in it and full sanding and repainting in about three years (normally). the wax is a key in this as it keeps the hull slick and shiny.

@2MeterTroll,

Sorry for the late reply
does this mean that you wouldn't bother to put an epoxy coat on the outside, but just epoxy and glass the bottom.
I'm asking this because I can buy good quality universal epoxy and a very good price, the same vendor also sells a sort of CPES called "Injecteer epoxy", which is more expensive.
Their epoxy is very good as glue, filler and is at least as liquid as varnish, since I'm quite good at painting, (maybe the only thing I'm really good in), I think it will brush out fine, I even used a brush to cover larger areas for gluing, and even with the cotton fibre mixed in it would brush out at the layer thickness I wanted.
Besides, I have read here onthe forum that epoxy can be painted over directly with a normal Alkyd paint, which would be good cost wise (I have a good addres for paint as well)

This whole project is a shoestring operation for the reason that I am dirt poor, (to give you an idea I might have to stop working on it for a week or two to be able to by a € 100 worth of epoxy) But above all a challenge to build something good for as little money as possible.

I would have to add up all the cash receipts, but I think that at this stage I sunk about € 1000 in it that is material and all the nessecary tools.

BTW I will cross plank the complete hull in Picea Abies 3 layers of 8.5 mm all epoxy glued.

Glassing the bottom is I think a good idea, what would you recomend, glass or dynell and what quality?

I expect to get a 10 year use out of it maximum, because I think as a rental boat the poor thing will not have an easy and pampered life.

Thanks for your advice,

Cheers

yes i would just stop with the fill coat and then paint it. 6 OZ fiberglass cloth will be fine. epoxy the inside as well. ten years is a good number, i am sure you can get ten years out of a rental. it just means you will have to fix things now and then. its a work boat and as a rental it needs to be able to be touched up so it looks good all the time. give your self a good base for paint and prime the hull with epoxy primer paint it and be done.

its a work boat dynell is a waste.
good luck. lots of folks have strong opinions about boats and how to construct them. me ive been in boat made from almost everything that would hold water out and am pretty happy if its dry inside and i dont have to fix something everyday.
