Re: modified malahini

Thanks guys. Bryan, I have been following and admiring your build. So, just to make sure I understand this properly, I could use 3/8(or metric equivalent) plywood in the aft portion of the bottom and 1/4(or metric equivalent) plywood plus veneer, to make up the difference in thickness, on the forwar...

Re: modified malahini

Returning briefly to the water line discussion, can an okoume plywood bottom be stained to match the mahogany veneer side planking at the bow between the chine and the water line or will I need to veneer that portion of the bottom as well? I prefer not to bring the bottom paint all the way to the ch...

Re: Geronimo's motorbox

Bob, I am building a Malahini but have been boating in a 18.5 ft Sea Ray bowrider with a 115 hp 4 stroke Mercury for 12 years. It has a 20 gallon tank. It depends on what kind of boating you are planning but 10 - 15 gallons of fuel has always met my needs, usually a full day of tubing, skiing, and c...

Malahini side planking question

I have a big weekend planned. The framework is faired. Side panels have been rough cut, joined, and dry fitted. Stem to transition joint properly trimmed and fitted. Today I purchased a small can of extra slow hardener(West 209). All that is left is to glue and screw. I really don't want to screw th...

Re: malahini stem question

I am using 6mm(~1/4 inch) Okoume. It took the side transom curve well so I think it will clamp into place on the stem. Love the batten idea. Thanks for the info and advice PeterG!

malahini stem question

I fabricated my stem according to the plans. The plans show a bit of concavity to the leading edge of the stem between the chine and the sheer. I didn't think much about this other than to notice it makes a nice visual line. However, now that I am dry fitting my side planking, the planking doesn't n...

Malahini sheer clamp blunder

I didn't glue or clamp sheer/transom frame junction while other while other sheer/frame junctions dried because I wasn't ready for transom frame to be permanently mounted yet. Therefore, the aft portion of sheer was not pulled in creating the proper bowing of the sheer line. Long story short, sheer ...

Re: Building a Malahini

See table saw jig on page 95 of Glen-L's book, "Boat Building With Plywood". This approach worked beautifully for me. Definitely attach transom frame to plywood before cutting bevel. I used steel screws initially and waited on the bronze and epoxy until later so I could still tweak transom...

Malahini transom questions

Is there any reason why the transom motor board cannot be made with lumber instead of plywood? I have a 10 inch wide sapele plank that I think will work and it would match the transom frame width so the knee would not require any additional shaving/fabrication. Also, what should the size of the tran...

Re: Monroe Mahalini

If building up your sheers and/or chines in laminations, scarf joints not necessary and butt joints adequate as adjacent laminations serve as butt blocks. I am doing my chines in triple laminations. The individual laminations are very easy to handle and bend effortlessly with no steam or boiling wat...

Re: Monroe Mahalini

I used 2 screws per gusset and the rest nails. This allowed me to dry fit the gusset and predrill for the nails. I used steel screws for the dry fit. When it came time to glue, I could align the screws and be confident my predrilled nail holes were therefore aligned. Just remember not to place screw...

Malahini chine /sheer questions

I opted for triple laminations for my chine. I am using sapele and read where others had some difficulty bending the sapele. The laminations bend and conform with wonderful ease. I have 2 questions for those experienced with laminations. 1. Is it better to glue and screw the first lamination to the ...

Re: Malahini in West Virginia

I have been admiring your mahogany veneer work. I was interested to know if you ended up using the clear contact paper approach per Bob Smith, the tie down ratchet straps for clamping vs some other clamping technique, and how you ended up lining off your hull. Beautiful work! Bob

Re: Lowe's Lumber Question

I have used the okoume ply from Berlin G Myers for my Malahini. Beautiful, wonderful to work with and worth the cost. My sapele lumber I ordered from the store in Michigan that Roberta reccomended, I think Johnson's. Also wonderful to work with and beautiful under epoxy. Cheaper to ship from Michiga...
