Hello all:

I am looking for find plans to build a heavy duty trailer - for my sailboat.

Capacity needs to be +/- 10,000 lbs, fin keel. It is to be used for my Catalina 27 . . . and possibly a future (slightly larger/heavier) boat in a few years.

I have already sourced the running gear (axles, wheels, hitch, brakes, etc.).

There seems to be a lot of plans available for a small or medium size "regular" boat trailer, but as we know, trailering a deep fin keel boat is a different matter.

Any ideas or suggestions out there, fellow sail-netters? Where can I find welding plans for something like this?



thx,

P

On the small side find and look at J24 trailers on the big side look at J105 trailers or anything TRIAD

You can also look at TRIADs web sight as they have hundreds of GOOD pictures

It is common to see the J24, J80 and J105 trailers which is why I bring then up

Hello all:

Here's a good source. Boat Trailor Plans | Glen-L Boat Plans

I used the Glen-L book to build a custom trailer for a 19 footer with a heavy full keel. I used the book to solve some design questions as I did this in 1998 and there was not much available on the internet back then. I never saw a real example of a sailboat trailer and needed some coaching for sure. My trailer turned out great and has saved me once an active hurricane season. I have a 20 foot square tubing hitch extension and lets me sink my trailer real deep at the ramp and my truck is bone dry.

I built a rolling A-frame trailer and fitted temporary bunks at the boatyard to haul the boat home. I then made custom curved bunks to support the hull properly and even made them removable so I can do bottom paint in my driveway, doing one side at a time. Its a lot of work though. Have you considered searching for a used trailer? I tried that at first and struck out so I welded my own as a last resort.

Good luck w the project, and don't use the cheapest (thin gauge) steel you can find. Get some heavy duty stuff and it will last forever.

thanks for your comments and suggestions.

Yes, I have searched and searched for a used trailer. I have been only able to find small trailers (undersized), or cobbled homebuilt, or very expensive custom built trailers.

Looking for a good/safe/cost effective way to solve this problem. :confused:

My son is a good welder, so I've got that covered. The plans have been my stumbling block. I'd like to use a design that is proven or engineered to safely carry the load.

One thought I had was to "borrow" one of our fellow cruisers trailers (a good heavy factory built model) and just "copy" all of the measurements, sizes, angles, lengths, etc. and a ton of pictures. :eek:

I guess the whole MT limits your trailer viewing :) as around here I see them everyday


So anyway how far and how much AIR clearance do you have as my 4.5 draft Cal just barely clears all the tree branches off main roads

Traffic lights and such are no problem


and that is with the keel 12" above the road :)

Did you try talking to Catalina? They closed their plant here in Woodland Hills, but it's just possilbe... They still have a keel mold sitting in the yard on the west side of the building, and who knows what they have inside. They've leased out their east lot for trucking storage, but I haven't seen any movement on dispostion of the property.

I'll tell you one thing you should NOT do. You should not buy the book "Trailers: How to Design and Build, Volume 1" by M.M. Smith. It is a complete waste of time and money. It is so high-level as to be useless.

Do I really need to buy a book to explain to me that a trailer's electrical system should include brake lights and turn signals? Seriously. The book spends about three pages, rambling on and on, and in the end tells you nothing more than that.

Or that the springs are intended to protect the cargo from bumps and potholes in the road? Given its title, I thought it might include some details on how to calculate spring loads, or determine their best location. But no, it went into no more detail than to explain that most trailers have springs, and they are to protect the cargo. Well, DUH!

Volume 2 might be useful. I don't know. Fool me once, shame on you; fool me twice, shame on me. As completely useless as Volume 1 was, I was not going to throw my money away on Volume 2 (which, by the way, costs more than Volume 1).

Personally, I would agree with the recommendation to go to the Glen-L site. Good luck.

suggestion.. build a cradle that will hold the boat well.. get a used flat bed trailer.. cheaper to find used then building new. Bolt the cradle to the trailer and you have a trailer to use for other things when the boat isn't on it!

This is a great idea! As long as you have plenty of truck to haul the extra weight of all the extra steel involved. You could even incorporate lift eyes on the cradle and have the boatyard crane or forklift lift your boat in the cradle and launch it. It also gives you the ability to position the cradle on the flatbed to adjust trailer tongue weight as needed. Have you thought about how will will raise/lower your mast?

I know of at least 2 people that have done that. It works out well!

I think Denise has the right idea. Two things to consider are width and whether you can legally travel over the roads and weight. Lots of trailers, even tandems are not rated high enough for a sailboat. Check the tonnage rating of whatever trailer you are looking at. You can get some house trailer axles fairly cheap sometimes but remember that you need brakes to make it legal. Making a boat trailer is not all that easy and you may find the cost of steel nowadays makes it marginally worthwhile to expend the effort.

A little anecdote, demonstrating the weight of sailboats: A fellow at the boatyard where I have kept my boat decided to make a trailer for his 48' sailboat, bought all the heavy steel I beams and channel iron, axles, etc. and welded it all up only to have it collapse about a mile down the road! The last time I was over that way the twisted trailer remained as a roadside eyesore at the edge of a cow pasture:)

I'm glad that it turned out so effectively and I hope it will continue in the future because it is so worthwhile and meaningful to the community. afkfdededgkcbeed
