3 inch block letters meet all boating regulations for size and shape. Visit the page below for complete details on the these letters and numbers.

These numbers are designed to be ironed onto inflatable boats.
They work with all thread-based brands, such as Zodiac, Bombard, Avon, Achilles, the SV series Sevylor boats, etc.
They will not work with the lighter duty Sevylor boats or on cordura fabric.

The letters are only available in the 3 inch block format. This material can't be ordered in sheets and alternative fonts are not available. The iron-on letters are designed for just one purpose and will only work on the above mentioned inflatable boat fabric.

NOTE: You will need to put the text for the desired registration or boat name in the Special Instructions field during checkout or we can't send the letters. We're good, but we can't read minds.

Be sure to order the correct number of letters; e.g. for 2 sets of this registration number: NY 1234 AB, you will need to purchase 16 letters. We will correct your order to match the text you submit if the count doesn't match.

PLEASE SPECIFY BLACK or WHITE IN THE SPECIAL INSTRUCTIONS, TOO. (otherwise, your order will be delayed while we email you to find the answer) Most states require a contrasting color for your registration. You shouldn't put white numbers on a white boat.

Be sure to order the adhesive backing sheets as well. One for each side.
